+\section{Introduction}
+Probably every chemist using \LaTeXe\ is aware of the great \paket{mhchem}
+package by Martin Hensel. There have always been some difficulties
+intertwining it with \chemmacros, though. Also, some other minor points in
+\paket{mhchem} always bothered me, but they hardly seemed enough for a new
+package. They weren't even enough for a feature request to the \paket{mhchem}
+author. The challenge and the fun of creating a new package and the wish for
+a highly customizable alternative led to \chemformula\ after all.
+
+\chemformula\ works very similar to \paket{mhchem} but is more strict as to how
+compounds, stoichiometric factors and arrows are input. In the same time
+\chemformula\ offers \emph{many} possibilities to customize the output.
+
+\sinceversion{4.0}Since version 4.0, the \chemformula\ package can be used
+independently from \chemmacros. This means that if you say
+\begin{beispiel}[code only]
+ \usepackage{chemformula}
+\end{beispiel}
+then \chemmacros\ will not be loaded. The \chemmacros\ package, however,
+\emph{will} load \chemformula.
+
+\section{Licence and Requirements}
+Permission is granted to copy, distribute and/or modify this software under
+the terms of the \LaTeX\ project public license (lppl) version 1.3 or later
+(\url{http://www.latex-project.org/lppl.txt}). The package has the status
+``maintained.''
+
+The \chemformula\ package needs and thus loads the packages \paket*{expl3}
+(from the \paket*{l3kernel}\footnote{\CTANurl{l3kernel}}), \paket*{xparse},
+\paket*{l3keys2e} and \paket*{xfrac} (from the
+\paket*{l3packages}\footnote{\CTANurl{l3packages}}),
+\paket*{tikz}\footnote{\CTANurl[graphics]{pgf}}, \paket{amsmath},
+\paket*{nicefrac} and \paket*{scrlfile} (from the
+\KOMAScript\footnote{\CTANurl{koma-script}} bundle).
+
+\section{Setup}
+All of \chemformula's options belong to \chemmacros' module
+\textcolor{module}{\code{chemformula}}. This means they can be setup with
+\begin{beispiel}[code only]
+ \chemsetup[chemformula]{<options>} or
+ \chemsetup{chemformula/<option1>,chemformula/<option2>}
+\end{beispiel}
+However, if you're using \chemformula\ as a standalone package the command
+\cmd{chemsetup} is not available. This is why \chemformula\ also has its own
+setup command:
+\begin{beispiel}[code only]
+ \setchemformula{<options>}
+\end{beispiel}
+
+\section{The Basic Principle}
+\chemformula\ offers one main command.
+\begin{beschreibung}
+ \Befehl{ch}[<options>]{<input>}
+\end{beschreibung}
+The usage will seem very familiar to you if you're familiar with \paket{mhchem}:
+\begin{beispiel}
+ \ch{H2O} \\
+ \ch{Sb2O3} \\
+ \ch{H+} \\
+ \ch{CrO4^2-} \\
+ \ch{AgCl2-} \\
+ \ch{[AgCl2]-} \\
+ \ch{Y^{99}+} \\
+ \ch{Y^{99+}} \\
+ \ch{H2_{(aq)}} \\
+ \ch{NO3-} \\
+ \ch{(NH4)2S} \\
+ \ch{^{227}_{90}Th+} \\
+ $V_{\ch{H2O}}$ \\
+ \ch{Ce^{IV}} \\
+ \ch{KCr(SO4)2 * 12 H2O}
+\end{beispiel}
+
+However, there are differences. The most notable one: \chemformula\
+distinguishes between different types of input. These different parts
+\emph{have} to be separated with blanks:
+\begin{beschreibung}
+ \Befehl{ch}{part1 part2 part3 part4}
+\end{beschreibung}
+A blank in the input \emph{never} is a blank in the output. This role of the
+blank strictly holds and disregarding it can have unexpected results and even
+lead to errors.
+
+Another notable difference: \chemformula\ tries to avoid math mode whenever
+possible:
+\begin{beispiel}
+ \ch{A + B ->[a] C} \\
+ \ce{A + B ->[a] C}
+\end{beispiel}
+
+This means that \cmd{ch}{2H2O} is recognized as a \emph{single} part, which in
+this case is recognized as a compound.
+\begin{beispiel}
+ \ch{2H2O} \\
+ \ch{2 H2O}
+\end{beispiel}
+This also means, that a part cannot contain a blank since this will
+automatically divide it into two parts. If you need an extra blank in the
+output you need to use \lstinline+~+. However, since commands in most cases
+gobble a space after them a input like \cmd{ch}{\textbackslash command ABC}
+will be treated as a single part. If you want or need to divide them you need
+to add an empty group: \cmd{ch}{\textbackslash command\{\} ABC}. The
+different input types are described in the following sections.
+
+% TODO: Module überdenken, Beschreibung anpassen
+There are some options to customize the output of the \cmd{ch} command. They
+can either be applied locally using the optional argument or can be set
+globally using the setup command. All options of \chemformula\ belong to the
+module \textcolor{module}{\code{chemformula}} and can be set in different
+ways:
+\begin{beschreibung}
+ \Befehl{chemsetup}[chemformula]{<options>} (when loaded via \chemmacros)
+ \Befehl{chemsetup}{chemformula/<options>} (when loaded via \chemmacros)
+ \Befehl{setchemformula}{<options>} (independent from \chemmacros)
+\end{beschreibung}
+
+\section{Stoichiometric Factors}\secidx{Stoichiometric Factors}
+A stoichiometric factor may only contain of numbers and the signs
+\lstinline+.,_/()+
+\begin{beispiel}
+ \ch{2} \\
+ \ch{12}
+
+ % decimals:
+ \ch{.5} \\
+ \ch{5,75}
+
+ % fractions:
+ \ch{3/2} \\
+ \ch{1_1/2}
+
+ % ``iupac'':
+ \ch{(1/2)}
+\end{beispiel}
+
+As you can see if you input decimal numbers a missing leading zero is added.
+
+You have to be a little bit careful with the right syntax but I believe it is
+rather intuitive.
+\begin{beispiel}[code only]
+ this won't work but will result in an error: \ch{1/1_1}
+\end{beispiel}
+
+If stoichiometric factors are enclosed with parentheses the fractions are not
+recognized and missing leading zeros are not added. What's inside the
+parentheses is typeset as is.
+\begin{beispiel}
+ \ch{(1/2) H2O} \ch{1/2 H2O} \ch{0.5 H2O}
+\end{beispiel}
+You can find many examples like the following for stoichiometric factors in
+parentheses in the \acs{iupac} Green Book~\cite{iupac:greenbook}:
+\begin{reaction*}
+ (1/5) K "\ox*{7,Mn}" O4 + (8/5) HCl == (1/5) "\ox*{2,Mn}" Cl2 + (1/2) Cl2 + (1/5) KCl + (4/5) H2O
+\end{reaction*}
+
+There are a few possibilities to customize the output.
+\begin{beschreibung}
+ \Option{decimal-marker}{<marker>}\Default{.}
+ The symbol to indicate the decimal.
+ \Option{frac-style}{math|xfrac|nicefrac}\Default{math}
+ Determines how fractions are displayed.
+ \Option{stoich-space}{<skip>}\Default{.1667em plus .0333em minus .0117em}
+ The space that is placed after the stoichiometric factor. A rubber
+ length.
+ \Option{stoich-paren-parse}{\default{true}|false}\Default{false}
+ If set to true stoichiometric factors enclosed by parentheses also are
+ parsed.
+\end{beschreibung}
+\begin{beispiel}
+ \ch[decimal-marker={,}]{3.5} \ch[decimal-marker={$\cdot$}]{3,5}
+\end{beispiel}
+
+The option \key{frac-style}{xfrac} uses the \lstinline+\sfrac+ command of the
+\paket{xfrac} package. The output strongly depends on the font you
+use.\secidx[xfrac]{Stoichiometric Factors}
+\begin{beispiel}
+ \ch[frac-style=xfrac]{3/2} \ch[frac-style=xfrac]{1_1/2}
+\end{beispiel}
+\chemformula\ defines the instance \lstinline=formula-text-frac= which you can
+redefine to your needs. See the \paket{xfrac} documentation for further
+information. The default definition is this:
+\begin{beispiel}[code only]
+ \DeclareInstance{xfrac}{chemformula-text-frac}{text}
+ {
+ slash-left-kern = -.15em ,
+ slash-right-kern = -.15em
+ }
+\end{beispiel}
+This document uses the font Linux Libertine~O and the following definition:
+\begin{beispiel}[code only]
+ \DeclareInstance{xfrac}{chemformula-text-frac}{text}
+ {
+ scale-factor = 1 ,
+ denominator-bot-sep = -.2ex ,
+ denominator-format = \scriptsize #1 ,
+ numerator-top-sep = -.2ex ,
+ numerator-format = \scriptsize #1 ,
+ slash-right-kern = .05em ,
+ slash-left-kern = .05em
+ }
+\end{beispiel}
+
+The option \key{frac-style}{nicefrac} uses the \lstinline+\nicefrac+ command
+of the \paket{nicefrac} package.\secidx[nicefrac]{Stoichiometric Factors}
+\begin{beispiel}
+ \ch[frac-style=nicefrac]{3/2} \ch[frac-style=nicefrac]{1_1/2}
+\end{beispiel}
+
+The option \key{stoich-space} allows you to customize the space between
+stoichiometric factor and the group following after
+it.\secidx[space]{Stoichiometric Factors}
+\begin{beispiel}
+ \ch{2 H2O} \\
+ \ch[stoich-space=.3em]{2 H2O}
+\end{beispiel}
+\secidx*{Stoichiometric Factors}
+
+\section{Compounds}\label{ssec:compounds}\secidx{Compounds}
+\chemformula\ determines compounds as the type that ``doesn't fit in anywhere
+else.'' This point will become more clear when you know what the other types
+are.
+\begin{beispiel}
+ \ch{H2SO4} \\
+ \ch{[Cu(NH3)4]^2+}
+\end{beispiel}
+
+\subsection{Adducts}\secidx[adducts]{Compounds}
+\chemformula\ has two identifiers which will create adducts.
+\begin{beschreibung}
+ \Befehl{ch}{A.B}\newline \ch{A.B}
+ \Befehl{ch}{A*B}\newline \ch{A*B}
+\end{beschreibung}
+\begin{beispiel}
+ \ch{CaSO4.H2O} \\
+ \ch{CaSO4*H2O}
+\end{beispiel}
+Since numbers in a compound always are treated as subscripts (see
+section~\ref{ssec:subscripts}) you sometimes need to introduce stoichiometric
+factors for the right output:
+\begin{beispiel}
+ \ch{Na3PO4*12H2O} \\
+ \ch{Na3PO4* 12 H2O} \\
+ \ch{Na3PO4 * 12 H2O}
+\end{beispiel}
+
+\subsection{Subscripts}\label{ssec:subscripts}\secidx[subscripts]{Compounds}
+\emph{All} numbers in a compound are treated as subscripts.
+\begin{beispiel}
+ \ch{H2SO4}
+\end{beispiel}
+If you want a letter to be a subscript you can use the math syntax:
+\begin{beispiel}
+ \ch{A_nB_m}
+\end{beispiel}
+The subscript recognizes groups. You can also use math inside it.
+\begin{beispiel}
+ \ch{A_{$n$}B_{$m$}} \\
+ \ch{NaCl_{(aq)}}
+\end{beispiel}
+
+\subsection{Commands}\secidx[commands]{Compounds}
+Commands are allowed in a compound:
+\begin{beispiel}
+ \ch{\textbf{A2}B3} \ch{A2\color{red}B3}
+\end{beispiel}
+
+However, if the commands demand numbers as argument, \eg, space commands or
+\chemmacros' \lstinline+\ox+ command the direct use will fail. This is
+because the numbers are treated as subscripts \emph{before} the command
+expands.
+\begin{beispiel}[code only]
+ \ch{A\hspace{2mm}B} will raise an error because \hspace sees something like
+ this: \hspace{$_2$mm}. Actually not at all like it but equally bad\ldots
+\end{beispiel}
+See section~\ref{ssec:text} for a way around this.
+
+\subsection{Charges and Other Superscripts}\secidx[charges]{Compounds}\secidx[superscripts]{Compounds}
+\paragraph{Basics}
+If a compound \emph{ends} with a plus or minus sign it will be treated as
+charge sign and typeset as superscript. In other places a plus is treated as
+a triple bond and a dash will be used as a single bond, see
+section~\ref{ssec:bonds}.
+\begin{beispiel}
+ \ch{A+B} \ch{AB+} \\
+ \ch{A-B} \ch{AB-}
+\end{beispiel}
+
+For longer charge groups or other superscripts you can use the math syntax.
+It recognizes groups and you can use math inside them. Inside these groups
+neither \code{+} nor \code{-} are treated as bonds. If a dot \code{.} is
+inside a superscript it is treated as indicator for a radical. A \code{*}
+gives the excited state.
+\begin{beispiel}
+ \ch{A^{x-}} \\
+ \ch{A^x-} \\
+ \ch{A^{x}-} \\
+ \ch{A^{$x-$}} \\
+ \ch{RNO2^{-.}} \\
+ \ch{^31H} \\
+ \ch{^{14}6C} \\
+ \ch{^{58}_{26}Fe} \\
+ \ch{NO^*}
+\end{beispiel}
+
+Ions and ion composites with more than one charge can be typeset quite as
+easy:
+\begin{beispiel}
+ \ch{SO4^2-} \ch{Ca^2+ SO4^2-}
+\end{beispiel}
+
+\paragraph{Charge Commands}\secidx[superscripts!charge commands]{Compounds}
+You don't need to use \cmd{mch} and related commands inside \cmd{ch}. Indeed,
+you \emph{shouldn't} use them as they might mess with the subscript and
+superscript alignment. The \chemmacros\ option \code{circled} is obeyed by
+\cmd{ch}.
+\begin{beispiel}
+ \chemsetup[option]{circled=all}
+ \ch{H+ + OH- <=> H2O}
+\end{beispiel}
+
+\paragraph{Behaviour}\secidx[superscripts!behaviour]{Compounds}
+The supercripts behave differently depending on their position in a compound,
+if there are super- and subscripts following each other directly.
+\begin{beispiel}
+ \ch{^33B} \ch{{}^33B} \ch{3^3B} \ch{B^3} \ch{B3^3} \\
+ \ch{^{23}_{123}B} \ch{{}^{23}_{123}B} \ch{_{123}^{23}B} \ch{B^{23}} \ch{B_{123}^{23}} \\
+ \ch{^{123}_{23}B} \ch{{}^{123}_{23}B} \ch{_{23}^{123}B} \ch{B^{123}} \ch{B23^{123}}
+\end{beispiel}
+\begin{itemize}
+\item If a compound \emph{starts} with a sub- or superscript both sub- and
+ superscript are aligned to the \emph{right} else to the \emph{left}.
+\item If a compound \emph{does not start} with a sub- or superscript and there
+ is both a sub- and a superscript, the superscript is shifted additionally by
+ a length determined from the option \key{charge-hshift}{<dim>}, also see
+ page~\pageref{desc:charge-hshift}f.
+\end{itemize}
+The second point follows \ac{iupac}'s recommendations:
+\begin{zitat}[{\acs{iupac} Green Book {\cite[][p.\,51]{iupac:greenbook}}}]
+ In writing the formula for a complex ion, spacing for charge number can be
+ added (staggered arrangement), as well as parentheses:
+ \ch[charge-hshift=full]{SO4^2-}, \ch{(SO4)^2-} The staggered arrangement is
+ now recommended.
+\end{zitat}
+
+\subsection{Bonds}\label{ssec:bonds}\secidx[bonds]{Compounds}
+\subsubsection{Native Bonds}
+There are three kinds of what I will call ``native bonds'':
+\begin{beispiel}
+ single: \ch{CH3-CH3} \\
+ double: \ch{CH2=CH2} \\
+ triple: \ch{CH+CH}
+\end{beispiel}
+
+\subsubsection{Flexible Bonds}
+\paragraph{Predefined Bonds}
+In addition to the three native bonds there are a few more which can be called
+by
+\begin{beschreibung}
+ \Befehl{bond}{<bond name>}
+\end{beschreibung}
+The predefined bond types are shown in table~\ref{tab:bond_types}.
+
+\begin{table}
+ \centering
+ \caption{Bonds available with \protect\cmd{bond}.}
+ \label{tab:bond_types}
+ \begin{tabular}{lcl}
+ \toprule
+ \bfseries name & \bfseries appearance & \bfseries aliases \\
+ \midrule
+ \code{single} & \bond{single} & \code{normal}, \code{sb} \\
+ \code{double} & \bond{double} & \code{db} \\
+ \code{triple} & \bond{triple} & \code{tp} \\
+ \code{dotted} & \bond{dotted} & \code{semisingle} \\
+ \code{deloc} & \bond{deloc} & \code{semidouble} \\
+ \code{tdeloc} & \bond{tdeloc} & \code{semitriple} \\
+ \code{co>} & \bond{co>} & \code{coordright} \\
+ \code{<co} & \bond{<co} & \code{coordleft} \\
+ \bottomrule
+ \end{tabular}
+\end{table}
+
+\begin{beispiel}
+ \ch{C\bond{sb}C\bond{db}C\bond{tp}C\bond{deloc}C\bond{tdeloc}C\bond{co>}C\bond{<co}C}
+\end{beispiel}
+
+\paragraph{Own Bonds}
+\chemformula\ offers commands to define own bond types:
+\begin{beschreibung}
+ \Befehl{DeclareChemBond}{<name>}\ma{<code>}
+ \Befehl{RenewChemBond}{<name>}\ma{<code>}
+ \Befehl{DeclareChemBondAlias}{<new name>}\ma{<old name>}
+ \Befehl{ShowChemBond}{<name>}
+\end{beschreibung}
+The usage is best described with an example. So let's see how the
+\code{single} bond and the \code{co>} bond are defined:
+\begin{beispiel}[code only]
+ \DeclareChemBond{single}
+ { \draw[chembond] (chemformula-bond-start) -- (chemformula-bond-end) ; }
+ \DeclareChemBond{coordright}
+ { \draw[chembond,butt cap->] (chemformula-bond-start) -- (chemformula-bond-end) ; }
+ \DeclareChemBondAlias{co>}{coordright}
+\end{beispiel}
+Two points are important: the names of the starting and the ending
+coordinates, \code{chemformula-bond-start} and \code{chemformula-bond-end},
+and the \TikZ style of the bonds \code{chembond}.
+
+So, let's say you want to define a special kind of dashed bond. You could do
+this:
+\begin{beispiel}
+ \usetikzlibrary{decorations.pathreplacing}
+ \makeatletter
+ \DeclareChemBond{dashed}
+ {
+ \draw[
+ chembond,
+ decorate,
+ decoration={ticks,segment length=\chemformula@bondlength/10,amplitude=1.5pt}]
+ (chemformula-bond-start) -- (chemformula-bond-end) ;
+ }
+ \makeatother
+ \chemsetup[chemformula]{bond-length=2ex}
+ \ch{C\bond{dashed}C}
+\end{beispiel}
+
+The last example showed you another macro:
+\makeatletter\cmd{chemformula@bondlength}\makeatother. It only exists so you
+can use it to access the bond length as set with \key{bond-length}
+directly.
+
+\subsection{Customization}\secidx[customization]{Compounds}\label{ssec:compounds:customization}
+These options allow you to customize the ouptut of the compounds:
+\begin{beschreibung}
+ \Option{subscript-vshift}{<dim>}\Default{0pt}
+ Extra vertical shift of the subscripts.
+ \Option{subscript-style}{text|math}\Default{text}
+ Style that is used to typeset the subscripts.
+ \Option{charge-hshift}{<dim>}\Default{.25em}
+ Shift of superscripts when following a subscript.\label{desc:charge-hshift}
+ \Option{charge-vshift}{<dim>}\Default{0pt}
+ Extra vertical shift of the superscripts.
+ \Option{charge-style}{text|math}\Default{text}
+ Style that is used to typeset the superscripts.
+ \Option{adduct-space}{<dim>}\Default{.1333em}
+ Space to the left and the right of the adduct point.
+ \Option{bond-length}{<dim>}\Default{.5833em}
+ The length of the bonds.
+ \Option{bond-offset}{<dim>}\Default{.07em}
+ Space between bond and atoms.
+ \Option{bond-style}{<tikz>}\Default{}
+ \TikZ\ options for the bonds.
+ \Option{radical-style}{<tikz>}\Default{}
+ \TikZ\ options for the radical point.
+ \Option{radical-radius}{<dim>}\Default{.2ex}
+ The radius of the radical point.
+ \Option{radical-hshift}{<dim>}\Default{.15em}
+ Horizontal shift before the radical point is drawn.
+ \Option{radical-vshift}{<dim>}\Default{.5ex}
+ Vertical shift relative to the current baseline.
+ \Option{radical-space}{<dim>}\Default{.15em}
+ Horizontal shift after the radical point is drawn.
+\end{beschreibung}
+
+Maybe you have noticed that charges of certain ions are shifted to the
+right.\secidx[charges!shift]{Compounds}
+\begin{beispiel}
+ \ch{SO4^2-} \ch{NH4+} \ch{Na+}
+\end{beispiel}
+They are shifted if they \emph{follow} a subscript which follows \ac{iupac}
+recommendations~\cite[][p.\,51]{iupac:greenbook}. The amount of the shift can
+be set with the option \key{charge-hshift}.
+\begin{beispiel}
+ \ch{SO4^2-} \ch{NH4+} \ch{Na+} \\
+ \chemsetup[chemformula]{charge-hshift=.5ex}
+ \ch{SO4^2-} \ch{NH4+} \ch{Na+} \\
+ \chemsetup[chemformula]{charge-hshift=.5pt}
+ \ch{SO4^2-} \ch{NH4+} \ch{Na+}
+\end{beispiel}
+
+Despite \ac{iupac}'s recommendation \chemformula\ does not make fully staggered
+arrangements in the default setting as I find it hard to read in some cases
+and ugly in others. Since this is a subjective decision \chemformula\ not only
+let's you define the absolute amount of the shift but also provides a
+possibility for full staggered arrangements. For this you have to use
+\key{charge-hshift}{full}.
+\begin{beispiel}
+ \ch[charge-hshift=0pt]{C5H11+} \ch[charge-hshift=0pt]{SO4^2-} \\
+ \ch{C5H11+} \ch{SO4^2-} \\
+ \ch[charge-hshift=1ex]{C5H11+} \ch[charge-hshift=1ex]{SO4^2-} \\
+ \ch[charge-hshift=full]{C5H11+} \ch[charge-hshift=full]{SO4^2-}
+\end{beispiel}
+
+If you don't want the charges to be typeset in text mode you can switch to
+math mode:
+\begin{beispiel}
+ \ch{M^x+} \ch{SO4^2-} \\
+ \chemsetup[chemformula]{charge-style = math}
+ \ch{M^x+} \ch{SO4^2-}
+\end{beispiel}
+
+The option \key{subscript-vshift} can be used to adjust the vertical shift of
+the subscripts:\secidx[subscripts!shift]{Compounds}
+\begin{beispiel}
+ \ch{H2SO4} \ch{Na3PO4} \\
+ \chemsetup[chemformula]{subscript-vshift=.5ex}
+ \ch{H2SO4} \ch{Na3PO4} \\
+ \chemsetup[chemformula]{subscript-vshift=-.2ex}
+ \ch{H2SO4} \ch{Na3PO4}
+\end{beispiel}
+
+You can choose the mode subscripts are typeset in the same way as it is
+possible for the charges:
+\begin{beispiel}
+ \ch{A_nB_m} \ch{H2SO4} \\
+ \chemsetup[chemformula]{subscript-style = math}
+ \ch{A_nB_m} \ch{H2SO4}
+\end{beispiel}
+
+The option \key{adduct-space} sets the space left and right to the adduct
+symbol $\cdot$.
+\begin{beispiel}
+ \ch{Na3PO3*H2O} \\
+ \chemsetup[chemformula]{adduct-space=.2em}
+ \ch{Na3PO3*H2O}
+\end{beispiel}
+
+Changing the length of the bonds:\secidx[bonds!length]{Compounds}
+\begin{beispiel}
+ \chemsetup[chemformula]{bond-length=4mm}%
+ single: \ch{CH3-CH3} \\
+ double: \ch{CH2=CH2} \\
+ triple: \ch{CH+CH}
+\end{beispiel}
+
+You can change the distance between bond and atom, too:
+\begin{beispiel}
+ \ch{H-H + N+N + O=O} \\
+ \ch[bond-offset=1pt]{H-H + N+N + O=O}
+\end{beispiel}
+
+\subsection{Standalone Formulae}\secidx[standalone]{Compounds}
+\noindent\sinceversion{4.0}\chemformula\ offers a command that \emph{only
+ accepts} the \enquote{compound} input type:
+\begin{beschreibung}
+ \Befehl{chcpd}[<options>]{<compound>}
+\end{beschreibung}
+\secidx*{Compounds}
+
+\section{Special Input Types}\secidx{Special Types}
+There are some \enquote{special type} input groups.
+
+\subsection{Single Token Groups}\secidx[single token groups]{Special Types}
+The first kind are groups which consist of only one token, namely of the
+following ones:
+\begin{beschreibung}
+ \Befehl{ch}{ + } \ch{ + }\newline
+ Creates the plus sign between compounds with space around it:\\
+ \cmd{ch}{2 Na + Cl2} \ch{2 Na + Cl2}
+ \Befehl{ch}{ v } \ch{ v }\newline
+ Sign for precipitate: \cmd{ch}{BaSO4 v} \ch{BaSO4 v}
+ \Befehl{ch}{ \lstinline+^+ } \ch{ ^ }\newline
+ Sign for escaping gas\footnotemark: \cmd{ch}{\lstinline=H2 ^=}
+ \ch{H2 ^}
+\end{beschreibung}
+\footnotetext{Is this the correct English term? Please correct me if it isn't.}
+
+The space left and right of the plus sign can be set with this option:
+\begin{beschreibung}
+ \Option{plus-space}{<skip>}\Default{.3em plus .1em minus .1em}
+ A rubber length.
+\end{beschreibung}
+\begin{beispiel}
+ \ch{A + B}\\
+ \ch[plus-space=4pt]{A + B}
+\end{beispiel}
+
+\subsection{Option Input}\secidx[option input]{Special Types}
+Sometimes you might want to apply an option only to a part of a, say,
+reaction. Of course you have the possibility to use \cmd{ch} several times.
+\begin{beispiel}
+ \ch{H2O +}\textcolor{red}{\ch{H2SO4}}\ch{-> H3O+ + HSO4-} \\
+ \ch{H2O +}\ch[subscript-vshift=2pt]{H2SO4}\ch{-> H3O+ + HSO4-}
+\end{beispiel}
+This, however, interrupts the input in your source and \emph{may} mess with
+the spacing. That's why there is an alternative:
+\begin{beschreibung}\makeatletter
+ \Befehl{ch}{ @\{<options>\} }\newline
+ The options specified this way will be valid \emph{only} until the next
+ compound is set.
+\end{beschreibung}
+\begin{beispiel}
+ \ch{H2O +}\textcolor{red}{\ch{H2SO4}}\ch{-> H3O+ + HSO4-} \\
+ \ch{H2O + @{format=\color{red}} H2SO4 -> H3O+ + HSO4-} \\
+ or of course:\\
+ \ch{H2O + \textcolor{red}{H2SO4} -> H3O+ + HSO4-}\\[1em]
+ \ch{H2O +}\ch[subscript-vshift=2pt]{H2SO4}\ch{-> H3O+ + HSO4-} \\
+ \ch{H2O + @{subscript-vshift=2pt} H2SO4 -> H3O+ + HSO4-}
+\end{beispiel}
+\secidx*{Special Types}
+
+\section{Escaped Input}\secidx{Escaped Input}
+In some cases it may be desirable to prevent \chemformula\ from parsing the
+input. This can be done in two ways.
+
+\subsection{Text}\label{ssec:text}\secidx[text]{Escaped Input}
+If you put something between \lstinline+" "+ or \lstinline+' '+ then the input
+will be treated as normal text, except that spaces are not allowed and have to
+be input with \lstinline+~+.
+\begin{beschreibung}
+ \Befehl{ch}{ "<escaped text>" }
+ \Befehl{ch}{ '<escaped text>' }
+\end{beschreibung}
+\begin{beispiel}
+ \ch{"\ox{2,Ca}" O} \\
+ \ch{"\ldots\," Na + "\ldots\," Cl2 -> "\ldots\," NaCl} \\
+ \ch{'A~->~B'}
+\end{beispiel}
+In many cases you won't need to escape the input. But when you get into
+trouble when using a command inside \cmd{ch} try hiding it.
+
+\subsection{Math}\secidx[math]{Escaped Input}
+If you especially want to input math you just enclose it with \lstinline+$ $+.
+This output is different from the escaped text as it is followed by a space.
+The reasoning behind this is that I assume math will mostly be used to replace
+stoichiometric factors.
+\begin{beschreibung}
+ \Befehl{ch}{ \string$<escaped math>\string$ }
+ \Befehl{ch}{ \string\(<escaped math>\string\) }
+\end{beschreibung}
+\begin{beispiel}
+ escaped text: \ch{"$x$" H2O} \\
+ escaped math: \ch{$x$ H2O} \\
+ also escaped math: \ch{\(x\) H2O} \\
+ \ch{$2n$ Na + $n$ Cl2 -> $2n$ NaCl}
+\end{beispiel}
+
+The space that is inserted after a math group can be edited:
+\begin{beschreibung}
+ \Option{math-space}{<skip>}\Default{.1667em plus .0333em minus .0117em}
+ A rubber length.
+\end{beschreibung}
+\begin{beispiel}
+ \ch{$2n$ Na + $n$ Cl2 -> $2n$ NaCl} \\
+ \chemsetup[chemformula]{math-space=.25em}
+ \ch{$2n$ Na + $n$ Cl2 -> $2n$ NaCl} \\
+ \ch{$A->B$}
+\end{beispiel}
+\secidx*{Escaped Input}
+
+\section{Arrows}\label{sec:arrows}\secidx{Arrows}
+\subsection{Arrow types}\secidx[types]{Arrows}
+Arrows are input in the same intuitive way they are with \paket{mhchem}.
+There are various different types:
+\begin{beschreibung}
+ \Befehl{ch}{ -> } \ch{->}\newline
+ standard right arrow
+ \Befehl{ch}{ <- } \ch{<-}\newline
+ standard left arrow
+ \Befehl{ch}{ -/> } \ch{-/>}\newline
+ does not react (right)
+ \Befehl{ch}{ </- } \ch{}</-\newline
+ does not react (left)
+ \Befehl{ch}{ <-> } \ch{<->}\newline
+ resonance arrow
+ \Befehl{ch}{ <> } \ch{<>}\newline
+ reaction in both directions
+ \Befehl{ch}{ == } \ch{==}\newline
+ stoichiometric equation
+ \Befehl{ch}{ <=> } \ch{<=>}\newline
+ equilibrium arrow
+ \Befehl{ch}{ \lstinline+<=>>+ } \ch{<=>>}\newline
+ unbalanced equilibrium arrow to the right
+ \Befehl{ch}{ \lstinline+<<=>+ } \ch{<<=>}\newline
+ unbalanced equilibrium arrow to the left
+ \Befehl{ch}{ <o> } \ch{<o>}\newline
+ isolobal arrow
+\end{beschreibung}
+All these arrows are drawn with \TikZ.
+\begin{beispiel}
+ \ch{H2 + Cl2 -> 2 HCl} \\
+ \ch{H2O + CO3^2- <=> OH- + HCO3-} \\
+ \ch{A <- B} \\
+ \ch{\{[CH2=CH-CH2]- <-> [CH2-CH=CH2]- \}} \\
+ \ch{A <> B} \\
+ \ch{H+ + OH- <=>> H2O} \\
+ \ch{2 NO2 <<=> N2O4}
+\end{beispiel}
+
+% TODO: add description for \charrow
+
+\subsection{Labels}\secidx[labels]{Arrows}
+The arrows take two optional arguments to label them.
+\begin{beschreibung}
+ \Befehl{ch}{ ->[<above>][<below>] }
+\end{beschreibung}
+\begin{beispiel}
+ \ch{A ->[a] B} \\
+ \ch{A ->[a][b] B} \\
+ \ch{A ->[\SI{100}{\celsius}] B}
+\end{beispiel}
+The label text can be parsed seperately from the arrow. The recipe is easy:
+leave blanks.
+\begin{beispiel}
+ \ch{A ->[H2O] B} \\
+ \ch{A ->[ H2O ] B} \\
+ \ch{A ->[ "\ox{2,Ca}" F2 ] B} \\
+ \ch{A ->[$\Delta$,~ \[H+ \]] B}
+\end{beispiel}
+% TODO: correct info about []
+
+If you leave the blanks \chemformula\ treats the groups inside the square
+brackets as seperated input types. The arrow reads its arguments
+\emph{afterwards}. As you can see the arrows \enquote{grow} with the length
+of the labels. What stays constant is the part that protrudes the labels. As
+you also can see in the last example square brackets inside the arrow
+arguments should be produced using \cmd{[} and \cmd{]}. They keep their usual
+meaning outside \cmd{ch}. These commands are necessary since the usual
+grouping (\ie hiding the brackets inside curly brackets) doesn't work due to
+the way \cmd{ch} reads its argument.
+\begin{beispiel}
+ \ch{A ->[a] B} \\
+ \ch{A ->[ab] B} \\
+ \ch{A ->[abc] B} \\
+ \ch{A ->[abc~abc] B} \\
+ % needs the `chemfig' package:
+ \setatomsep{15pt}
+ \ch{A ->[ "\chemfig{-[:30]-[:-30]OH}" ] B} \\
+ \ch{A ->[[]] B} vs. \ch{A ->[\[\]] B}
+\end{beispiel}
+
+\subsection{Customization}\secidx[customization]{Arrows}
+These are the options which enable you to customize the arrows:
+\begin{beschreibung}
+ \Option{arrow-offset}{<dim>}\Default{.75em}
+ This is the length that an arrow protrudes a label on both sides. This
+ means an empty arrow's length is two times \code{arrow-offset}.
+ \Option{arrow-min-length}{<dim>}\Default{0pt}
+ The minimal length an error must have unless two times \key{arrow-offset}
+ plus the width of the label is larger.
+ \Option{arrow-yshift}{<dim>}\Default{0pt}
+ Shifts an arrow up (positive value) or down (negative value).
+ \Option{arrow-ratio}{<factor>}\Default{.6}
+ The ratio of the arrow lengths of the unbalanced equilibrium. \code{.4}
+ would mean that the length of the shorter arrow is $0.4\times$ the length
+ of the longer arrow.
+ \Option{compound-sep}{<dim>}\Default{.5em}
+ The space between compounds and the arrows.
+ \Option{label-offset}{<dim>}\Default{2pt}
+ The space between the labels and the arrows.
+ \Option{label-style}{<font command>}\Default{\cmd*{footnotesize}}
+ The relative font size of the labels.
+\end{beschreibung}
+
+The following code shows the effect of the different options on the \lstinline+<=>>+
+arrow:
+\begin{beispiel}
+ standard: \ch{A <=>>[x][y] B} \\
+ longer: \ch[arrow-offset=12pt]{A <=>>[x][y] B} \\
+ higher: \ch[arrow-yshift=2pt]{A <=>>[x][y] B} \\
+ more balanced: \ch[arrow-ratio=.8]{A <=>>[x][y] B} \\
+ labels further away: \ch[label-offset=4pt]{A <=>>[x][y] B} \\
+ larger distance to compounds: \ch[compound-sep=2ex]{A <=>>[x][y] B} \\
+ smaller labels: \ch[label-style=\tiny]{A <=>[x][y] B}
+\end{beispiel}
+
+\subsection{Modify Arrow Types}\label{sec:arrows_modify}\secidx[types!modify]{Arrows}
+The arrows are defined with the command
+\begin{beschreibung}
+ \Befehl{DeclareChemArrow}{<tokens>}\ma{<tikz>}
+\end{beschreibung}
+\ma{<tokens>} is the sequence of tokens that is replaced with the actual arrow
+code. For example the basic arrow is defined via
+\begin{beispiel}[code only]
+ \DeclareChemArrow{->}{\draw[-cf] (cf_arrow_start) -- (cf_arrow_end) ;}
+\end{beispiel}
+In order to define arrows yourself you need to know the basics of
+\TikZ\footnote{Please see the \textsf{pgfmanual} for details.}. There are
+some predefined coordinates you can and should use:
+\begin{description}
+ \item[\code{(cf\_arrow\_start)}] The beginning of the arrow.
+ \item[\code{(cf\_arrow\_end)}] The end of the arrow.
+ \item[\code{(cf\_arrow\_mid)}] The mid of the arrow.
+ \item[\code{(cf\_arrow\_mid\_start)}] The beginning of the shorter arrow in
+ types like \lstinline+<=>>+.
+ \item[\code{(cf\_arrow\_mid\_end)}] The end of the shorter arrow in types like
+ \lstinline+<=>>+.
+ \item[\code{cf}, \code{left cf}, \code{right cf}] \chemformula's own arrow
+ heads.
+\end{description}
+\begin{beispiel}
+ \DeclareChemArrow{.>}{\draw[-cf,dotted,red] (cf_arrow_start) -- (cf_arrow_end);}
+ \DeclareChemArrow{n>}{\draw[-cf] (cf_arrow_start) .. controls ([yshift=3ex]cf_arrow_mid) .. (cf_arrow_end);}
+ \ch{A .> B} \ch{A .>[a][b] B} \ch{A n> B}
+\end{beispiel}
+If you want to redefine an existing arrow there are two commands you can use:
+\begin{beschreibung}
+ \Befehl{RenewChemArrow}{<tokens>}\ma{<tikz>}
+ \Befehl{ShowChemArrow}{<tokens>}
+\end{beschreibung}
+The second one gives the current definition, the first one redefines an existing
+arrow.
+\begin{beispiel}
+ \texttt{\ShowChemArrow{->}} \\
+ \RenewChemArrow{->}{\draw[->,red] (cf_arrow_start) -- (cf_arrow_end) ;}
+ \texttt{\ShowChemArrow{->}} \\
+ \ch{A -> B}
+\end{beispiel}
+
+\subsection{Standalone Arrows}\secidx[standalone]{Arrows}
+\noindent\sinceversion{4.0}\chemformula\ offers a command that \emph{only
+ accepts} the \enquote{arrow} input type:
+\begin{beschreibung}
+ \Befehl{charrow}{<arrow>}\oa{<above>}\oa{<below>}
+\end{beschreibung}
+\secidx*{Arrows}
+
+\section{Names}\secidx{Names}
+\subsection{Syntax}\secidx[syntax]{Names}
+\chemformula\ has a built-in syntax to write text under a compound. In a way
+it works very similar to the arrows.
+\begin{beschreibung}
+ \Befehl{ch}{ !(<name>)( <formula> ) }
+\end{beschreibung}
+If an exclamation mark is followed by a pair of parentheses \chemformula\ will
+parse it this way:
+\begin{beispiel}
+ \ch{!(ethanol)( CH2CH2OH )}
+\end{beispiel}
+The same what's true for the arrows arguments holds for these arguments: if
+you leave blanks the different parts will be treated according to their input
+type before the text is set below the formula.
+\begin{beispiel}
+ \ch{!(water)(H2O)} \quad
+ \ch{!( "\textcolor{blue}{water}" )( H2O )} \quad
+ \ch{!( $2n-1$ )( H2O )} \quad
+ \ch{!( H2O )( H2O )} \quad
+ \ch{!(oxonium)( H3O+ )}
+\end{beispiel}
+If for some reason you want to insert an exclamation mark \emph{without} it
+creating a name you only have to make sure it isn't followed by parentheses.
+\begin{beispiel}
+ \ch{H2O~(!)} \\
+ \ch{A!{}()}
+\end{beispiel}
+
+% TODO add description of \chname command
+
+\subsection{Customization}\secidx[customization]{Names}
+\chemformula\ provides two options to customize the output of the names:
+\begin{beschreibung}
+ \Option{name-format}{<commands>}\Default{\cmd*{scriptsize}\cmd*{centering}}
+ The format of the name. This can be arbitrary input.
+ \Option{name-width}{<dim>|auto}\Default{auto}
+ The width of the box where the label is put into. \code{auto} will detect
+ the width of the name and set the box to this width.
+\end{beschreibung}
+\begin{beispiel}
+ \ch{!(acid)( H2SO4 ) -> B} \\
+ \ch[name-format=\sffamily\small]{!(acid)( H2SO4 ) -> B} \\
+ \ch[name-format=\scriptsize N:~]{!(acid)( H2SO4 ) -> B} \\
+ \ch[name-width=3em,name-format=\scriptsize\raggedright]{!(acid)( H2SO4 ) -> B}
+\end{beispiel}
+
+\subsection{Standalone Names}\secidx[standalone]{Names}
+\noindent\sinceversion{4.0}\chemformula\ offers a command that allows the
+usage of the \enquote{name} syntax in normal text. This is the command that
+a bang is replaced with in \chemformula's formulas, actually. Both arguments
+are mandatory.
+\begin{beschreibung}
+ \Befehl{chname}\da{<under>}\da{<text>}
+\end{beschreibung}
+\secidx*{Names}
+
+\section{Format and Font}\secidx{Format and Font}\label{sec:format}
+In the standard setting \chemformula\ doesn't make any default changes to the
+font of the formula output. Let's take a look at a nonsense input which shows
+all features:
+\begin{beispiel}
+ \newcommand*\sample{%
+ \ch{H2C-C+C-CH=CH+ + CrO4^2-
+ <=>[x][y]
+ 2.5 Cl^{-.} + 3_1/2 Na*OH_{(aq)} + !(name)( A^n ) "\LaTeXe"}
+ }
+ \sample
+\end{beispiel}
+\newcommand*\sample{%
+ \ch{H2C-C+C-CH=CH+ + CrO4^2-
+ <=>[x][y]
+ 2.5 Cl^{-.} + 3_1/2 Na*OH_{(aq)} + !(name)( A^n ) "\LaTeXe"}
+}
+
+Now we're going to change different aspects of the font a look what happens:
+\begin{beispiel}[below]
+ \sffamily Hallo \sample \\
+ \ttfamily Hallo \sample \normalfont \\
+ \bfseries Hallo \sample \normalfont \\
+ \itshape Hallo \sample
+\end{beispiel}
+As you can see most features adapt to the surrounding font.
+
+If you want to change the default format you need to use this option:
+\begin{beschreibung}
+ \Option{format}{<anything>}\Default{}
+ Adds arbitrary code before the output of \cmd{ch}.
+\end{beschreibung}
+\begin{beispiel}
+ \definecolor{newblue}{rgb}{.1,.1,.5}
+ \chemsetup[chemformula]{format=\color{newblue}\sffamily}
+ \sffamily Hallo \sample \\
+ \ttfamily Hallo \sample \normalfont \\
+ \bfseries Hallo \sample \normalfont \\
+ \itshape Hallo \sample
+\end{beispiel}
+
+You can also specifically change the fontfamily, fontseries and fontshape of
+the output.
+\begin{beschreibung}
+ \Option{font-family}{<family>}\Default{}
+ Changes the fontfamily of the output with
+ \lstinline+\fontfamily{<family>}\selectfont+.
+ \Option{font-series}{<series>}\Default{}
+ Changes the fontseries of the output with
+ \lstinline+\fontseries{<series>}\selectfont+.
+ \Option{font-shape}{<shape>}\Default{}
+ Changes the fontshape of the output with
+ \lstinline+\fontshape{<shape>}\selectfont+.
+\end{beschreibung}
+\begin{beispiel}
+ \chemsetup[chemformula]{font-series=bx}
+ Hallo \sample \\
+ \sffamily Hallo \sample \normalfont \\
+ \chemsetup[chemformula]{font-family=lmr,font-series=m} Hallo \sample \normalfont \\
+ \itshape Hallo \sample
+\end{beispiel}
+
+If you're using \XeLaTeX\ or \LuaLaTeX\ and have loaded \paket{fontspec} you
+have the possibilty to set the font with it:
+\begin{beschreibung}
+ \Option{font-spec}{\{<font>\}}\Default{}
+ or with options
+ \Option{font-spec}{\{[<options>]<font>\}}
+\end{beschreibung}
+\begin{beispiel}
+ \chemsetup[chemformula]{font-spec={Linux Biolinum O}} \sample \\
+ \chemsetup[chemformula]{font-spec={Augie}} \sample \\
+ \chemsetup[chemformula]{font-spec={Latin Modern Sans}} \sample \\
+ \bfseries \sample \normalfont
+\end{beispiel}
+\secidx*{Format and Font}
+
+\section{Usage In Math Equations}\secidx{Math Environments}
+The \cmd{ch} command can be used inside math equations. It recognizes
+\lstinline+\\+ and \lstinline+&+ and passes them on. However, you can't use
+the optional arguments of \lstinline+\\+ inside \cmd{ch}.
+\begin{beispiel}
+ \begin{align}
+ \ch{
+ H2O & ->[a] H2SO4 \\
+ Cl2 & ->[x][y] CH4
+ }
+ \end{align}
+ \begin{align*}
+ \ch{
+ RNO2 &<=>[ + e- ] RNO2^{-.} \\
+ RNO2^{-.} &<=>[ + e- ] RNO2^2-
+ }
+ \end{align*}
+\end{beispiel}
+\secidx*{Math Environments}
+
+\section{Further Examples}
+This section presents some examples of a possible usage.
+

+ 2 MeLi + CuI &-> !(\cstack{Dimethylcuprat\\(Gilmann-Cuprat)})( Me2CuLi ) + Li
+ \end{reactions*}
+\end{beispiel}
+
+\begin{beispiel}
+ % needs `chemfig'
+ \begin{reactions*}
+ H3C-CH3 + Cl2 &->[$\Delta$][$h\nu$] H3CCH2Cl + HCl & &"\Enthalpy{-27.1}" \\

+ \end{reactions*}
+\end{beispiel}
+
+The following example shows how the cancelling of compounds could be done%
+\footnote{Inspired by a question on TeX.SE: \url{http://tex.stackexchange.com/q/30118/5049}}.
+\begin{beispiel}

+\section{Introduction}
+The \chemgreek\ package is an auxiliary package for other chemistry packages
+such as \chemmacros. In chemistry there is often the need for upright greek
+letters. The \chemgreek\ package provides an interface to various other
+packages that provide upright greek letters. One could mention
+\paket{textgreek}, \paket{upgreek}, \paket[fonts]{newtx} or
+\paket[fonts]{kpfonts}. All of these packages provide upright greek letters,
+some a whole alphabet some only the upright variants of the standard italic
+symbols for which macros are defined in base \LaTeX.
+
+\chemgreek\ offers a possibility to map those different interfaces to a
+unified set of macros for usage in a chemistry package.
+
+\section{Licence and Requirements}
+Permission is granted to copy, distribute and/or modify this software under
+the terms of the \LaTeX\ project public license (lppl) version 1.3 or later
+(\url{http://www.latex-project.org/lppl.txt}). The package has the status
+``maintained.''
+
+\chemgreek\ loads the following packages:
+\paket*{expl3}\footnote{\CTANurl{l3kernel}} and
+\paket*{xparse}\footnote{\CTANurl{l3packages}}.
+
+\section{Define Mappings}
+
+\chemgreek's main commands are:
+\begin{beschreibung}
+ \Befehl{newchemgreekmapping}{<name>}\ma{<mapping list>}\newline
+ Add a new mapping to \chemgreek. Issue an error if it already exists.
+ \Befehl{renewchemgreekmapping}{<name>}\ma{<mapping list>}\newline
+ Renew a \chemgreek\ mapping. Issue an error if it doesn't exist yet.
+ \Befehl{newchemgreekmapping}{<name>}\ma{<mapping list>}\newline
+ Declare a new mapping to \chemgreek. If the mapping already exists it
+ will be overwritten.
+\end{beschreibung}
+
+The command \cmd{newchemgreekmapping} needs to get a comma separated list of
+24 pairs divided by a slash. The first entry is the lowercase version und the
+second the uppercase version for the corresponding greek letter at the current
+position. This will become clearer if you look at how the \code{default}
+mapping is defined:
+
+\begin{beispiel}[code only]
+\newchemgreekmapping{default}
+ {
+ \ensuremath{\alpha} / \ensuremath{\mathrm{A}} , % 1: alpha
+ \ensuremath{\beta} / \ensuremath{\mathrm{B}} , % 2: beta
+ \ensuremath{\gamma} / \ensuremath{\Gamma} , % 3: gamma
+ \ensuremath{\delta} / \ensuremath{\Delta} , % 4: delta
+ \ensuremath{\epsilon} / \ensuremath{\mathrm{E}} , % 5: epsilon
+ \ensuremath{\zeta} / \ensuremath{\mathrm{Z}} , % 6: zeta
+ \ensuremath{\eta} / \ensuremath{\mathrm{H}} , % 7: eta
+ \ensuremath{\theta} / \ensuremath{\Theta} , % 8: theta
+ \ensuremath{\iota} / \ensuremath{\mathrm{I}} , % 9: iota
+ \ensuremath{\kappa} / \ensuremath{\mathrm{K}} , % 10: kappa
+ \ensuremath{\lambda} / \ensuremath{\Lambda} , % 11: lambda
+ \ensuremath{\mu} / \ensuremath{\mathrm{M}} , % 12: mu
+ \ensuremath{\nu} / \ensuremath{\mathrm{N}} , % 13: nu
+ \ensuremath{\xi} / \ensuremath{\Xi} , % 14: xi
+ \ensuremath{o} / \ensuremath{\mathrm{O}} , % 15: omikron
+ \ensuremath{\pi} / \ensuremath{\Pi} , % 16: pi
+ \ensuremath{\rho} / \ensuremath{\mathrm{P}} , % 17: rho
+ \ensuremath{\sigma} / \ensuremath{\Sigma} , % 18: sigma
+ \ensuremath{\tau} / \ensuremath{\mathrm{T}} , % 19: tau
+ \ensuremath{\upsilon} / \ensuremath{\Upsilon} , % 20: upsilon
+ \ensuremath{\phi} / \ensuremath{\Phi} , % 21: phi
+ \ensuremath{\psi} / \ensuremath{\Psi} , % 22: psi
+ \ensuremath{\chi} / \ensuremath{\mathrm{X}} , % 23: chi
+ \ensuremath{\omega} / \ensuremath{\Omega} % 24: omega
+ }
+\end{beispiel}
+
+There \emph{must} be 24 pairs of entries, i.e., a complete mapping! Those
+entries are the ones that will be used by the interface macros. For each
+letter a pair \cmd{Chemalpha}/\cmd{ChemAlpha} is defined that uses the entries
+of the currently active mapping. That means there are 48 (robust) macros
+defined each beginning with \cmd*{Chem...} followed by the lowercase or
+uppercase name of the Greek letter.
+
+The default mapping is -- as you can probably see -- \emph{not an upright
+ one}. This is because \chemgreek\ will not make any choice for a specific
+package but let's the user (or another package) choose. The \chemmacros\
+package for example provides a package option that selects one of the
+available mappings.
+
+\begin{beispiel}
+ Default mapping: \Chemphi\ and \ChemPhi, $\phi$ and $\Phi$
+\end{beispiel}
+
+\section{Predefined Mappings and Selection of a Mapping}
+\chemgreek\ predefines some mappings. Some of the mappings require additional
+packages to be loaded. The mapping names and the required packages are listed
+in table~\ref{tab:mappings}.
+
+\begin{table}[hbp]
+ \centering
+ \begin{tabular}{>{\ttfamily}ll}
+ \toprule
+ \tablehead{mapping} & \tablehead{package} \\
+ \midrule
+ default & --- \\
+ var-default & --- \\
+ textgreek & \paket*{textgreek} \\
+ upgreek & \paket*{upgreek} \\
+ newtx & \paket*{newtxmath} \\
+ kpfonts & \paket*{kpfonts} \\
+ \bottomrule
+ \end{tabular}
+ \caption{Predefined mappings.}
+ \label{tab:mappings}
+\end{table}
+
+A mapping is selected and activated with one of the following commands:
+\begin{beschreibung}
+ \Befehl{activatechemgreekmapping}*[<options>]{<name>}\newline
+ This commands selects and activates the mapping \code{<name>}. If the
+ star variant is used also the package \code{<name>} is loaded with options
+ \code{<options>}. This obviously only makes sense if the package name is
+ the same as the mapping name. The command can only be used in the
+ document preamble.
+ \Befehl{selectchemgreekmapping}{<name>}
+ This commands selects and activates the mapping \code{<name>}. A required
+ package has to be loaded additionally the usual way via \cmd*{usepackage}
+ or \cmd*{RequirePackage}. The command can be used throughout the
+ document.
+\end{beschreibung}
+
+\begin{beispiel}
+ % requires the `newtxmath' package to be loaded:
+ \Chemphi\ and \ChemPhi, $\phi$ and $\Phi$\par
+ \selectchemgreekmapping{newtx}
+ \Chemphi\ and \ChemPhi, $\upphi$ and $\upPhi$
+\end{beispiel}
+
+\section{Changing a Specific Symbol in an Existing Mapping}
+If you should want to change a specifig entry of a specific mapping it would
+be rather tedious to redefine the whole mapping. That is why \chemgreek\
+provides a command for that purpose:
+\begin{beschreibung}
+ \Befehl{changechemgreeksymbol}{<mapping name>}\ma{upper|lower}\ma{<entry
+ name>}\ma{<entry>}\newline
+ Changes the \code{upper}- or \code{lower}case entry \code{<entry name>} in
+ the mapping \code{<mapping name>}.
+\end{beschreibung}
+
+In order to activate the change you need the (re-) activate the affected
+mapping afterwards:
+\begin{beispiel}
+ \changechemgreeksymbol{default}{lower}{alpha}{xxx}
+ \selectchemgreekmapping{default}
+ \Chemalpha
+\end{beispiel}
+

-\section{Lizenz, Voraussetzungen und README}
-Das \chemmacros-Bundle steht unter der \LaTeX\ Project Public License (LPPL) Version
-1.3 oder später (\url{http://www.latex-project.org/lppl.txt}) und hat den Status
-„maintained“.
-
-Das \chemmacros-Bundle benötigt aktuelle Versionen der \paket{l3kernel}- und
-\paket{l3packages}-Bundles. Außerdem werden die Pakete \paket{siunitx},
-\paket{mathtools}, \paket{bm}, \paket{nicefrac} und \paket{environ} sowie
-\paket*{tikz}\footnote{CTAN: \href{http://www.ctan.org/pkg/pgf/}{pgf}} und die
-\TikZ libraries \code{calc} und \code{arrows} benötigt.
-
-Die Paketoption \key{bpchem} (Abschnitt \ref{sec:optionen}) benötigt \paket{bpchem},
-die Paketoption \key{xspace} benötigt \paket{xspace} und die Paketoption
-\key{method}{mhchem} benötigt \paket{mhchem}.
-
-Mit v3.0 wurde das \chemmacros-Paket mit den neuen Paketen \chemformula und \ghsystem
-gebündelt. \chemformula ist eine Alternative zu \paket{mhchem}. Das führte zu
-einigen internen Änderungen bei \chemmacros. Gleichzeitig wurde die Dokumentation
-komplett überarbeitet.
-
-Vielleicht erinnern Sie Sich, dass \chemmacros' Optionen alle verschiedenen Modulen
-angehören, siehe Abschnitt \ref{sec:setup} für weitere Informationen. Sie werden
-in den linken Rand geschrieben, wenn die Option das erste Mal erwähnt wird. Abschnitt
-\ref{sec:overview} listet alle Optionen von \chemmacros und ihre Module auf. In
-diesem Dokument werden Optionen \textcolor{key}{\code{grün}} und Module
-\textcolor{module}{\code{rot}} dargestellt.
-
-Das Paket \ghsystem benötigt die Pakete \chemmacros, \paket{tabu}, \paket{longtable},
-\paket{ifpdf} und \paket{graphicx}.
-
-\achtung{Es gibt einige veraltete Befehle und Optionen, die in dieser Dokumentation
-nicht mehr beschrieben werden. Um Kompatibilität mit älteren Dokumenten zu
-gewährleisten, sind sie immer noch definiert. Diese Befehle geben eine Warnung aus.
-In Zukunft könnten sie nicht mehr definiert sein.}
-
-\section{Motivation und Hintergrund}
-\chemmacros entstand vor einigen Jahren als wachsende Liste von Makros, die ich
-häufig verwendete. Ich kann mich nicht mehr genau erinnern, wann und warum ich
-entschied, sie als Paket zu veröffentlichen. Nun \textendash\ hier ist es und ich
-hoffe, Sie werden das eine oder andere ebenfalls nützlich finden.
-
-Die Makros und ihre Funktionsweise haben sich im Laufe der Zeit leicht verändert.
-Es sind außerdem eine ganze Reihe hinzugekommen. Insgesamt hat sich mit der Zeit
-vieles vereinheitlicht und es sind viele Anpassungsmöglichkeiten hinzugekommen.
-
-Wohl fast jeder Chemiker, der \LaTeX\ für seine Dokumente verwendet, dürfte das
-großartige Paket \paket{mhchem} von Martin Hensel kennen. Es gab immer ein paar
-Schwierigkeiten, \paket{mhchem} und \chemmacros zur Zusammenarbeit zu bewegen.
-Ein paar Kleinigkeiten in \paket{mhchem} haben mich zudem immer gestört, aber sie
-schienen nicht genug für ein neues Paket. Noch nicht einmal genug, um ein
-\enquote{feature request} an den Autoren von \paket{mhchem} zu senden. Die
-Herausforderung und der Spaß, ein neues Paket zu erschaffen, sowie der Wunsch nach
-größtmöglicher Flexibilität führten so doch noch zu \chemformula.
-
-\chemformula funktioniert sehr ähnlich wie \paket{mhchem}, ist aber strenger was
-das Eingeben von Verbindungen, stöchiometrischen Faktoren und Pfeilen angeht.
-Gleichzeitig bietet \chemformula ein paar Möglichkeiten, den Output anzupassen,
-die \paket{mhchem} nicht bietet. Da \chemformula als Alternative zu \paket{mhchem}
-gedacht ist, bietet \chemmacros eine Option, mit der Sie zwischen \paket{mhchem}
-und \chemformula wählen können.
-
-Als Chemiker wissen Sie vermutlich, dass die \acl{UN} das \ac{ghs} als weltweiten
-Ersatz für die zahlreichen ähnlichen aber doch verschiedenen Systeme der einzelnen
-Länder entwickelt haben. Obwohl es noch nicht in allen Ländern umgesetzt
-wurde~\cite{unece:ghsystem_implementation}, ist das nur eine Frage der Zeit.
-Das Paket \ghsystem gibt Ihnen nun die Möglichkeit, alle \enquote{hazard and
-precautionary statements} auf einfache Weise einzugeben und aufzurufen. Die Sätze
-wurden der EU-Verordnung 1272/2008 entnommen~\cite{eu:ghsystem_regulation}.
-
-Ich hoffe, folgende vier Punkte in diesem Bundle umgesetzt zu haben:
-\begin{itemize}
- \item intuitive Verwendung, vor allem im Hinblick auf die Syntax der Befehle
- \item die Befehle sollen nicht nur das Schreiben erleichtern sondern auch den
- Quelltext besser lesbar machen, indem er semantisch logischer wird
- (\lstinline=\ortho-dichlorobenzene= kann man leichter lesen und verstehen als
- \lstinline=\textsl{o}-dichlorobenzene=)
- \item so große Flexibilität und so viele Anpassungsmöglichkeiten wie möglich,
- damit jeder Anwender die Befehle nach eigenen Bedürfnissen anpassen kann.
- \item mit \ac{iupac} konforme Voreinstellungen
-\end{itemize}
-Vor allem der letzte Punkt benötigte zwar einige Schubser von Anwendern\footnote{%
-Vielen Dank an Dr.~Paul~King!}, um die richtigen Einstellungen an vielen Stellen
-zu bekommen. Wenn Ihnen etwas auf\-fällt, das nicht der \ac{iupac}-Empfehlung
-entspricht\footnote{Das gilt nicht für den \cmd{ox}-Befehl. Die \ac{iupac}-Fassung dazu
-ist \cmd[oxa]{ox*}.}, würde ich mich über eine E-Mail sehr freuen!
-
-Bei einem Paket dieser Größe mit alten und neuen Teilen (die man noch als in der
-Beta-Phase befindlich betrachten muss) ist es unvermeidbar, dass es Fehler und Bugs
-gibt. Ich bin sehr daran interessiert, dieses Paket zu korrigieren und verbessern,
-daher eine Bitte: wenn Ihnen etwas auf{}fällt, das Sie stört, egal wie geringfügig
-es erscheint, senden Sie mir bitte eine E-Mail und ich werde sehen, was ich tun
-kann. Besonders interessiert bin ich an Feedback zu \chemformula (siehe
-Teil~\ref{part:chemformula}) und \ghsystem (siehe Teil~\ref{part:ghsystem}), freue
-mich aber natürlich auch über Feedback zu jedem anderen Teil des Bundles.
-
-\section{Installation und Laden des Bundles}\secidx{Laden des Bundles}\secidx{Installation}
-Das Bundle enthält drei Style-Dateien\footnote{Die mit der Endung \code{sty}.},
-einem Ordner namens \code{language/}, der die Sprach-De\-fi\-ni\-tions-Dateien für
-\ac{ghs} enthält (Endung \code{def}) und einem Ordner \code{pictures/}, der \code{eps}-,
-\code{jpg}-, \code{pdf} und \code{png}-Dateien enthält (die \ac{ghs} Piktogramme).
-Wenn Sie das Bundle von Hand installieren, \emph{bitte achten Sie darauf, die Ordner
-\code{language/} und \code{pictures/} in den \emph{gleichen} Ordner wie die
-Style-Dateien zu kopieren}.
-
-Das Laden von \chemmacros via
-\begin{beispiel}[code only]
- \usepackage{chemmacros} % `chemmacros', `chemformula' and `ghsystem' are loaded
-\end{beispiel}
-wird ebenso \chemformula und \ghsystem laden. Sie können jedoch \chemmacros davon
-abhalten, \ghsystem zu laden:
-\begin{beispiel}[code only]
- \usepackage[ghsystem=false]{chemmacros} % `chemmacros' and `chemformula' are loaded
-\end{beispiel}
-Das Laden von \chemformula kann nicht verhindert werden, da \chemmacros und
-\chemformula miteinander interagieren.
-
-Das explizite Laden von \chemformula \bzw\ \ghsystem ist möglich und wird
-\chemmacros in jedem Fall laden, falls das noch nicht geschehen ist. Dadurch
-laden sie sich implizit gegenseitig.
-\begin{beispiel}[code only]

-\section{Paketoptionen}\label{sec:optionen}\secidx{Paketoptionen}
-\chemmacros hat einige Optionen. Sie alle folgen einen Schlüssel/Wert-Prinzip:
-\begin{beispiel}[code only]
- \usepackage[option1 = <value1>, option2 = <value2>]{chemmacros}
-\end{beispiel}
-Die meisten können auch ohne Wert verwendet werden
-(\lstinline+\usepackage[option]{chemmacros}+). Sie verwenden dann den
-\default{unter\-stri\-che\-nen} Wert.
-
-Sowohl \chemformula als auch \ghsystem haben keine eigenen Paketoptionen. Wenn Sie
-sie explizit laden, verpuffen alle als Paketoptionen gegebenen Optionen. Sie können
-dann nur mit dem Setup-Befehl gesetzt werden.
-\begin{beschreibung}
- % bpchem
- \option[option]{bpchem}{\default{true}|false} Diese Option lädt \paket{bpchem}
- und passt das Layout von \cmd{NMR} den \paket{bpchem}-Befehlen \lstinline+\HNMR+
- und \lstinline+\CNMR+ an. Default = \code{false}
- % circled
- \option[option]{circled}{\default{formal}|all|none} \chemmacros unterscheidet
- zwischen zwei Typen von Ladungen\footnote{Vielen Dank an Christoph Schäfer,
- der mich darauf aufmerksam machte, dass v1.1 die Ladungen zu nachlässig behandelte!}:
- reale ($+/-$) und formale (\fplus/\fminus) Ladungen. Die Option \code{formal}
- unterscheidet zwischen ihnen, \code{none} stellt alle ohne Umkreisung dar,
- \code{all} umkreist alle. Default = \code{formal}
- % circletype
- \option[option]{circletype}{\default{chem}|math} Diese Option schaltet zwischen
- zwei Darstellungsmöglichkeiten für formale Ladungen hin und her: \cmd{fplus}
- \fplus\ und \lstinline+$\oplus$+ $\oplus$. Default = \code{chem}
- % cmversion
- \option[option]{cmversion}{1|2|bundle} Diese Option stellt die Definition einiger
- Befehle wieder her, so dass Dokumente, die mit v1.* gesetzt wurden, Korrekt
- kompilieren. Default = \code{bundle}. Eigentlich sind \code{2} und \code{bundle}
- Aliase. Diese Option kann nur in der Präambel gesetzt werden.
- % ghsystem
- \option[option]{ghsystem}{\default{true}|false} Das Paket \ghsystem abschalten.
- Die Einstellung \key{ghs}{false} wird das Laden von \ghsystem unterbinden.
- Default = \code{true}
- % greek
- \option[option]{greek}{auto|math|textgreek|\default{upgreek}} Diese Option bestimmt,
- wie die Buchstaben \cmd{Chemalpha} und seine Verwandten dargestellt werden.
- Siehe Seite~\pageref{desc:upgreek} für weitere Informationen. Diese Option
- kann nur in der Präambel gesetzt werden. Bitte beachten Sie, dass diese
- Option weder \paket{upgreek} noch \paket{textgreek} lädt! Sie bestimmt
- lediglich welches verwendet wird, falls es geladen wurde. Wenn Sie beispielsweise
- \code{upgreek} wählen, müssen Sie auch das entsprechende Paket laden.
- Default = \code{auto}
- % iupac
- \option[option]{iupac}{auto|restricted|strict} Einstellen, wie die Nomenklatur-Befehle
- definiert werden. Siehe Seite~\pageref{desc:iupac}. Default = \code{auto}
- % language
- \option[option]{language}{american|british|english|french|german|italian|ngerman}
- Sprachspezifische Einstellungen laden. \code{english}, \code{american} und
- \code{british} sind Aliase, ebenso \code{german} und \code{ngerman}. Diese
- Option kann nur in der Präambel gesetzt werden. Default = \code{english}
- % method
- \option[option]{method}{\default{chemformula}|mhchem} Sie können wählen, ob
- \chemmacros \paket{mhchem} oder \chemformula für die Reaktionsumgebungen
- (siehe Abschnitt~\ref{sec:reactions}) und die Teilchen (siehe
- Abschnitt~\ref{sec:teilchen}) verwendet. Default = \code{chemformula}. Diese
- Option kann nur in der Präambel gesetzt werden.
- % Nu
- \option[option]{Nu}{\default{chemmacros}|mathspec} Das Paket \paket{mathspec}
- definiert ebenfalls ein Makro \cmd{Nu}. Diese Option entscheidet, welche
- Definition gilt, siehe Seite~\pageref{Nu}. Default = \code{chemmacros}. Diese
- Option kann nur in der Präambel gesetzt werden.
- % strict
- \option[option]{strict}{\default{true}|false} Die Einstellung \key{strict}{true}
- wird alle Warnungen in Fehlermeldungen ändern. Default = \code{false}
- % synchronize
- \option[option]{synchronize}{\default{true}|false} Mit der Einstellung \code{true}
- wird \chemmacros die Schrifteinstellungen von \chemformula übernehmen, falls
- \chemformula als Methode gewählt wurde. Default = \code{false}. Um diese Option
- zu demonstrieren, wurde dieses Dokument mit \key{synchronize}{true} und der
- \chemformula Einstellung
- \lstinline+\chemsetup[chemformula]{font-spec={[Color=darkgray]Latin Modern Sans}}+
- gesetzt.
- % xspace
- \option[option]{xspace}{\default{true}|false} Mit dieser Option werden die
- meisten Makros mit einem \lstinline+\xspace+ definiert. Default = \code{true}

-\section{Setup}\label{sec:setup}\secidx{Setup}
-Zahlreiche der Befehle von \chemmacros, \chemformula und \ghsystem haben
-Schlüssel/Wert-Paare als Optionen, mit denen sie angepasst werden können. Meistens
-können sie als (optionales) Argument des entsprechenden Befehls verwendet werden.
-Meistens können Sie auch mit dem \cmd{chemsetup} Befehl verwendet werden.
-\begin{beschreibung}
- \Befehl{chemsetup}[<module>]{<key> = <value>} oder
- \Befehl{chemsetup}{<module>/<key> = <value>}
-\end{beschreibung}
-Die Optionen gehören alle zu einem Modul, das anzeigt, auf welchen Befehl sie
-sich auswirken. Wenn eine Option vorgestellt wird, wird das dazugehörige Modul
-in den linken Rand geschrieben. Sie können die Optionen mit \cmd{chemsetup} auf
-zwei Weisen verwenden, wie oben dargestellt.
-
-Die Paketoptionen können ebenfalls als Optionen betrachtet werden, die zum Modul
-\textcolor{module}{\ttfamily option} gehören. Das bedeutet, sie können auch mit
-\cmd{chemsetup} aufgerufen werden.
-\begin{beispiel}
- \chemsetup[option]{circled=none}\mch\ \pch\ \fmch\ \fpch\ \el\ \prt \\
- \chemsetup[option]{circled=formal}\mch\ \pch\ \fmch\ \fpch\ \el\ \prt \\
- \chemsetup[option]{circletype=math}\mch\ \pch\ \fmch\ \fpch\ \el\ \prt \\
- \chemsetup{option/circletype=chem,option/circled=all}\mch\ \pch\ \fmch\ \fpch\ \el\ \prt \\
- \chemsetup{option/circletype=math}\mch\ \pch\ \fmch\ \fpch\ \el\ \prt
-\end{beispiel}
-Optionen, die \emph{keinem} Modul angehören, können \emph{nicht} mit
-\cmd{chemsetup} verwendet werden!
-
-Alle Optionen von \chemformula gehören dem Modul \textcolor{module}{\code{chemformula}}
-an und alle Optionen von \ghsystem gehören dem Modul \textcolor{module}{\code{ghs}}
-an.

-\section{Teilchen, Ionen und Symbole}\label{sec:teilchen}\secidx{Teilchen, Ionen und Symbole}
-\subsection{Vordefiniert}\secidx[vordefiniert]{Teilchen, Ionen und Symbole}
-\chemmacros definiert einige einfache Makros, um häufig verwendete Teilchen und
-Symbole darzustellen. Bitte beachten Sie, dass sie unterschiedlich dargestellt
-werden, je nach dem, welche Paketoptionen Sie verwenden. Diese Befehle können
-auch im Mathematikmodus eingesetzt werden.
-\begin{beschreibung}
- \befehl{Hpl} \Hpl (Proton)
- \befehl{Hyd} \Hyd (Hydroxid)
- \befehl{HtO} \HtO (Oxoniumion) (\textbf{H} \textbf{t}hree \textbf{O})
- \befehl{water} \water
- \befehl{el} \el (Elektron)
- \befehl{prt} \prt (Proton)
- \befehl{ntr} \ntr (Neutron)
- \befehl{Nu} \Nu (Nukleophil). Das Paket \paket{mathspec} definiert ebenfalls
- ein Makro \cmd{Nu}. Wenn Sie die Paketoption \key[option]{Nu}{mathspec} wählen,
- definiert \chemmacros stattdessen \cmd{Nuc}\label{Nu}.
- \befehl{El} \El (Elektrophil)
- \befehl{ba} \ba (Base)
- \befehl{fplus} \fplus
- \befehl{fminus} \fminus
- \befehl{transitionstatesymbol} \transitionstatesymbol
- \befehl{standardstate} \standardstate. Dieses Symbol wird nur dann von \chemmacros
- bereitgestellt, wenn das Paket \paket{chemstyle} nicht geladen wurde. Die Idee
- ist von dort ausgeliehen\footnote{Vielen Dank an den Paketautoren
- \href{http://www.texdev.net/}{Joseph Wright}.}.
- \befehl{Chemalpha} \Chemalpha
- \befehl{Chembeta} \Chembeta
- \befehl{Chemgamma} \Chemgamma
- \befehl{Chemdelta} \Chemdelta
- \befehl{Chemepsilon} \Chemepsilon
- \befehl{Chemeta} \Chemeta
- \befehl{Chemkappa} \Chemkappa
- \befehl{Chemmu} \Chemmu
- \befehl{Chemnu} \Chemnu
- \befehl{Chemrho} \Chemrho
- \befehl{Chempi} \Chempi
- \befehl{Chemsigma} \Chemsigma
- \befehl{Chemomega} \Chemomega
- \befehl{ChemDelta} \ChemDelta
-\end{beschreibung}
-
-\achtung{Der Befehl \cmd{Rad} wird nicht mehr bereitgestellt!}
-
-Die beiden Teilchen \cmd{Nu} und \cmd{ba} können angepasst werden. Dafür verwenden
-Sie die Option
-\begin{beschreibung}
- \Option[particle]{elpair}{false|\default{dots}|dash}
-\end{beschreibung}
-Sie hat nur dann Auswirkungen, wenn das Paket \paket{chemfig} geladen wurde, da
-sie dessen Befehl \lstinline+\Lewis+ verwendet.
-\begin{beispiel}
- % needs package `chemfig'
- \ba[elpair] \Nu[elpair=dash]
-
- \chemsetup[particle]{elpair}
- \ba \Nu
-\end{beispiel}
-
-\label{desc:upgreek}Die griechischen Buchstaben sind keine neu definierten Zeichen
-sondern werden abhängig von den Paketen, die sie geladen haben, definiert. Die
-Default-Version entspricht den entsprechenden kursiven „Mathematik“-Buchstaben.
-Wenn Sie das Paket \paket{textgreek} geladen haben, werden dessen Buchstaben verwendet.
-Wenn Sie das Paket \paket{upgreek} geladen haben, werden dessen Buchstaben verwendet.
-Diese Dokumentation verwendet \paket{upgreek}. Haben Sie sowohl \paket{textgreek}
-als auch \paket{upgreek} geladen haben, wird \paket{upgreek} verwendet.
-
-Wenn Sie nicht wollen, dass \chemmacros automatisch wählt, sondern selbst entscheiden
-wollen, verwenden Sie die Paketoption \key[option]{greek}. Tabelle~\ref{tab:upgreek_mode}
-zeigt die verschiedenen Varianten einiger Buchstaben.
-
-\begin{table}[h]
- \centering
- \begin{tabular}{lccc}\toprule
- & math & upgreek & textgreek \\\midrule
- \cmd{Chemalpha} & $\alpha$ & $\upalpha$ & \textalpha \\
- \cmd{Chembeta} & $\beta$ & $\upbeta$ & \textbeta \\
- \cmd{ChemDelta} & $\Delta$ & $\Updelta$ & \textDelta \\ \bottomrule
- \end{tabular}
- \caption{Die griechischen Buchstaben}\label{tab:upgreek_mode}
-\end{table}
-
-Der Grund dafür, dass \chemmacros diese Makros überhaupt definiert, ist \ac{iupac}-Konformität.
-\ac{iupac} empfiehlt, aufrechte griechische Buchstaben in der Nomenklatur verwenden.
-
-\begin{zitat}[{\ac{iupac} Green Book {\cite[][p.\,9]{iupac:greenbook}}}]
- Greek letters are used in systematic organic, inorganic, macromolecular and
- biochemical nomenclature. These should be roman (upright), since they are not
- symbols for physical quantities.
-\end{zitat}
-
-\chemmacros verwendet diese Befehle nun, um Nomenklatur-Befehle zu definieren, siehe
-Seite~\pageref{par:greek_letters}.
-
-\subsection{Eigene Teilchen definieren}\secidx[eigene]{Teilchen, Ionen und Symbole}
-Manchmal kann es sicherlich nützlich sein, andere Teilchen als Makro zur Verfügung
-zu haben, etwa \lstinline+\positron+ oder \lstinline+\photon+. Mit diesem Befehl
-kann das einfach erreicht werden:
-\begin{beschreibung}
- \Befehl{DeclareChemParticle}{<cmd>}\ma{<definition>}
- \Befehl{RenewChemParticle}{<cmd>}\ma{<definition>}
-\end{beschreibung}
-Abhängig von der \key{method}, die Sie als Option gewählt haben, wird die
-\code{<definition>} entweder mit \paket{mhchem} oder mit \chemformula erfolgen.
-Das Teilchen verhält sich wie die vordefinierten mit einer Ausnahme: das Teilchen,
-das auf diese Weise definiert wurde, gehorcht der Option \key{circled} nur, wenn
-Sie \key{method}{chemformula} gewählt haben. Wenn Sie mit \key{method}{mhchem}
-formale Ladungen wollen, müssen Sie \chemmacros' Befehle (siehe
-Abschnitt~\ref{sec:ladungen}) explizit einsetzen.
-\begin{beispiel}
- % uses the `upgreek' package
- \DeclareChemParticle{\positron}{$\upbeta$+}
- \DeclareChemParticle{\photon}{$\upgamma$}
- \RenewChemParticle{\el}{$\upbeta$-}
- \positron\ \photon\ \el
-\end{beispiel}
-\cmd{DeclareChemParticle} definiert das Teilchen nur dann, wenn \code{<cmd>} noch
-nicht existiert. Andernfalls wird \chemmacros entweder eine Warnung oder einen
-Fehler ausgeben, abhängig von der Option \key{strict}. \cmd{RenewChemParticle}
-definiert ein Teilchen \emph{nur}, wenn \code{<cmd>} schon existiert und gibt
-andernfalls eine Warnung/einen Fehler.

-\section{Nomenklatur, Stereodeskriptoren und lateinische Ausdrücke}\label{sec:stereo}
-\subsection{IUPAC-Namen}\secidx{IUPAC-Namen}
-Ähnlich wie das Paket \paket{bpchem} stellt \chemmacros einen Befehl\footnote{Die
-Idee und die Umsetzung stammt aus dem Paket \paket*{bpchem} von Bjørn Pedersen.}
-bereit, um \ac{iupac}-Namen zu setzen. Wieso ist das nützlich? \ac{iupac}-Namen können
-sehr lang werden. So lang, dass sie auch mal über mehr als zwei Zeilen gehen können,
-vor allem in zweispaltigen Dokumenten. Das bedeutet, sie müssen sich mehr als
-einmal umbrechen dürfen. Dabei hilft folgender Befehl:
-\begin{beschreibung}
- \befehl{iupac}{<IUPAC name>} Innerhalb dieses Befehls werden {\catcode`\|=11\cmd{|}}
- und \cmd{-} verwendet, um Umbruchstellen oder einen umbrechenden Bindestrich
- anzugeben. {\catcode`\^=11\cmd{^}} kann als Abkürzung für\\
- \lstinline=\textsuperscript= eingesetzt werden.
-\end{beschreibung}
-\begin{beispiel}
- \begin{minipage}{.4\linewidth}
- \iupac{Tetra\|cyclo[2.2.2.1\^{1,4}]\-un\|decane-2\-dodecyl\-5\-(hepta\|decyl\|iso\|dodecyl\|thio\|ester)}
- \end{minipage}
-\end{beispiel}
-Der Befehl \cmd{iupac} ist dennoch mehr ein semantischer Befehl. Meistens kann man
-(beinahe) dasselbe erreichen, indem man \cmd{-} anstelle von {\catcode`\|=11\cmd{|}}
-verwendet, \code{-} anstelle von \cmd{-} und \lstinline=\textsuperscript= anstelle
-von {\catcode`\^=11\cmd{^}}.
-
-Es gibt subtile Unterschiede: \cmd{-} fügt einen kleinen Leerraum vor dem Bindestrich
-ein und entfernt etwas Raum danach. Der Befehl {\catcode`\|=11\cmd{|}} verhindert
-nicht nur Ligaturen, sondern fügt ebenfalls einen kleinen Leerraum ein.
-\begin{beispiel}
- \huge\iupac{2,4\-Di\|chlor\|pentan} \\
- 2,4-Dichlorpentan
-\end{beispiel}
-
-Die eingefügten Leerräume können angepasst werden:
-\begin{beschreibung}
- \option[iupac]{hyphen-pre-space}{<dim>} Default = \code{.01em}
- \option[iupac]{hyphen-post-space}{<dim>} Default = \code{-.03em}
- \option[iupac]{break-space}{<dim>} Default = \code{.01em}
-\end{beschreibung}
-
-Der Befehl \cmd{iupac} dient noch einem anderen Zweck. Unabhängig von der
-Paketoption \key[option]{iupac} sind alle Befehle, die in diesem Abschnitt
-vorgestellt werden, \emph{innerhalb} von \cmd{iupac} immer definiert. Eine ganze
-Reihe der Nomenklatur-Befehle haben sehr allgemeine Namen: \cmd{meta}, \cmd{D},
-\cmd{E}, \cmd{L}, \cmd{R}, \cmd{S}, \cmd{trans} und so weiter. Das bedeutet,
-dass sie entweder schon definiert sind (\cmd{L} \L) oder leicht von anderen
-Paketen oder Klassen definiert werden (das Paket \paket{cool} definiert zum
-Beispiel sowohl \cmd{D} als auch \cmd{E}). Um Ihnen Kontrolle darüber zu geben,
-welche Befehle wie definiert sind, gibt es die Paketoption
-\key[option]{iupac}\label{desc:iupac}. Sie hat drei Modi:
-\begin{itemize}
- \item \key{iupac}{auto}: wenn der Befehl \emph{nicht} von einem Paket oder einer
- Klasse, die sie verwenden, definiert wird, ist er generell verfügbar, sonst nur
- \emph{innerhalb} von \cmd{iupac}.
- \item \key{iupac}{restricted}: alle Nomenklatur-Befehle sind \emph{nur} innerhalb
- von \cmd{iupac} definiert. Wenn sie von einem anderen Paket definiert sind, sind
- sie natürlich außerhalb verfügbar. Ansonsten sind sie außerhalb nicht definiert.
- \item \key{iupac}{strict}: \chemmacros überschreibt jede bestehende Definition und
- macht die Befehle im ganzen Dokument verfügbar. Sie können natürlich (nur nach
- \lstinline=\begin{document}=) umdefiniert werden. Sie behalten dann die
- Nomenklatur-Bedeutung innerhalb von \cmd{iupac}.
-\end{itemize}
-Tabelle~\ref{tab:iupac_modes} demonstriert die verschiedenen Modi.
-
-\begin{table}[h]

-\subsubsection{Eigene Nomenklatur-Befehle}\secidx[eigene]{IUPAC-Namen}
-Wenn Ihnen Befehle fehlen sollten, können Sie neue definieren.
-\begin{beschreibung}
- \Befehl{DeclareChemIUPAC}{<cmd>}\ma{<declaration>}
- \Befehl{RenewChemIUPAC}{<cmd>}\ma{<declaration>}
-\end{beschreibung}
-Ein Befehl, der in dieser Weise definiert wurde, gehorcht der Option \key[option]{iupac}.
-Das bedeutet, dass bestehende Befehle nur überschrieben werden, wenn Sie die
-Paketoption \key{iupac}{strict} verwenden. \cmd{DeclareChemIUPAC} wird jedoch die
-Definition eines bestehenden Nomenklatur-Befehls \emph{nicht} überschreiben,
-sondern eine Warnung/einen Fehler melden (abhängig von der Paketoption \key{strict}).
-\begin{beispiel}
- \DeclareChemIUPAC\endo{\textit{endo}}
- \RenewChemIUPAC\anti{\textit{anti}}
- \iupac{(2\-\endo,7\-\anti)\-2\-bromo\-7\-fluoro\|bicyclo[2.2.1]heptane}
-\end{beispiel}
-
-\cmd{RenewChemIUPAC} erlaubt Ihnen, die vordefinierten Befehle umzudefinieren.

-\subsection{Lateinische Ausdrücke}\secidx{Lateinische Ausdrücke}[Lateinische Ausdruecke]
-Das Paket \paket{chemstyle} stellt den Befehl \cmd{latin} bereit, um gebräuchliche
-lateinische Ausdrücke konsistent darzustellen. \chemmacros definiert ein ähnliches
-\cmd{latin}, aber nur, wenn \paket{chemstyle} \emph{nicht} geladen wurde, und
-stellt zusätzlich diese Befehle bereit:
-\begin{beschreibung}
- \befehl{insitu} \insitu
- \befehl{abinitio} \abinitio
- \befehl{invacuo} \invacuo
-\end{beschreibung}
-
-Falls das Paket \paket{chemstyle} geladen wurde, wurden sie mit \paket{chemstyle}s
-Befehl \lstinline+\latin+ definiert. Das bedeutet, dass ihr Erscheinungsbild von

-\paket{siunitx} stellt den Befehl \lstinline+\DeclareSIUnit{<command>}{<unit>}+
-zur Verfügung, um beliebige Einheiten zu definieren. \chemmacros verwendet diesen
-Befehl, um die unten gelisteten Einheiten zu definieren. Wie alle
-\paket{siunitx}-Einheiten sind sie nur innerhalb von \lstinline+\SI{<num>}{<unit>}+
-und \lstinline+\si{<unit>}+ gültig.
-\begin{beschreibung}

- \befehl{atm} \si{\atm}
- \befehl{calory} \si{\calory}
- \befehl{cal} \si{\cal}
- \befehl{cmc} \si{\cmc} Die Einheiten \cmd{cmc}, \cmd{molar} und \cmd{Molar} werden
- durch das Paket \paket{chemstyle} ebenfalls definiert. \chemmacros definiert
- sie nur, wenn \paket{chemstyle} nicht geladen wurde.
- \befehl{molar} \si{\molar}

-\section{Oxidationszahlen, reale und formale Ladungen}\label{sec:ladungen}
-\chemmacros unterscheidet zwischen realen ($+$/$-$) und formalen (\fplus/\fminus)
-Ladungssymbolen, siehe auch Abschnitt \ref{sec:optionen}. Alle Befehle, die
-formale Ladungen ausgeben, starten mit einem \code{f}.
-
-\subsection{Ionenladungen}\label{ssec:ionen}\secidx{Ionenladungen}
-Einfache Verwendung von (realen) Ladungen. Man sollte anmerken, dass diese
-Befehle aus der Zeit stammen, als \chemmacros sich stark bemühte, mit
-\paket{mhchem} kompatibel zu sein, und es \Chemformula noch nicht gab. Sie
-werden weiterhin zur Verfügung gestellt, aber meine Empfehlung wäre, \cmd{ch}
-(siehe~\ref{part:chemformula}) zu verwenden und diese Befehle zu vergessen:
-\begin{beschreibung}
- \befehl{pch}[<number>] positive Ladung (\textbf{p}lus + \textbf{ch}arge)
- \befehl{mch}[<number>] negative Ladung (\textbf{m}inus + \textbf{ch}arge)
-\end{beschreibung}
-
-\begin{beispiel}
- \pch, Na\pch, Ca\pch[2]\\
- \mch, F\mch, S\mch[2]
-\end{beispiel}
-
-Das gleiche für formale Ladungen:
-\begin{beschreibung}
- \befehl{fpch}[<number>] positive Ladung
- \befehl{fmch}[<number>] negative Ladung
-\end{beschreibung}
-
-\begin{beispiel}
- \fpch\ \fmch\ \fpch[3] \fmch[3]
-\end{beispiel}
-
-Es gibt eine Option, die das Verhalten der Ladungen beeinflusst:
-\begin{beschreibung}
- \option[charges]{append}{\default{true}|false} Wenn auf \code{true} gesetzt,
- wird die Ladung mit einer leeren Gruppe angehängt. Default = \code{false}
-\end{beschreibung}
-
-Das hat folgende Auswirkungen:
-\begin{beispiel}
- % uses package `mhchem'
- \chemsetup{charges/append=false,phases/pos=sub}
- \ce{H\pch\aq} \ce{H\aq\pch}
-
- \chemsetup[charges]{append=true}
- \ce{H\pch\aq} \ce{H\aq\pch}
-\end{beispiel}
-
-In den meisten Fällen wird das Verhalten unerwünscht sein, es kann jedoch
-Gelegenheiten geben, wo es nützlich sein kann:
-\begin{beispiel}
- \chemsetup{charges/append=false,phases/pos=sub}
- \ce{\ox{1,H}\pch\aq}
-
- \chemsetup[charges]{append=true}
- \ce{\ox{1,H}\pch\aq}
-\end{beispiel}

-\subsection{Oxidationszahlen}\label{ssec:oxidationszahlen}\secidx{Oxidationszahlen}
-Eingabe von Oxidationszahlen:
-\begin{beschreibung}
- \befehl{ox}[<options>]{<number>,<atom>} setzt \code{<number>} über \code{<atom>};
- \code{<number>} muss eine (rationale) Zahl sein!
-\end{beschreibung}
-
-\begin{beispiel}
- \ox{+1,Na}, \ox{2,Ca}, \ox{-2,S}, \ox{-1,F}
-\end{beispiel}
-
-Es gibt eine Reihe von Optionen, mit denen \cmd{ox} angepasst werden kann.
-\begin{beschreibung}
- \option[ox]{parse}{\default{true}|false} Wenn \code{false}, dann kann ein beliebiger
- Eintrag für \code{<number>} gemacht werden. Default = \code{true}
- \option[ox]{roman}{\default{true}|false} schaltet von römischen auf arabische
- Ziffern um. Default = \code{true}
- \option[ox]{pos}{top|super|side}; \code{top} setzt \code{<number>} über \code{<atom>},
- \code{super} rechts oben als Hochstellung und \code{side} rechts daneben in
- Klammern. Default = \code{top}
- \option[ox]{explicit-sign}{\default{true}|false} gibt $+$ für positive Zahlen
- und $\pm$ für die $0$ aus. Default = \code{false}
- \option[ox]{decimal-marker}{comma|point} Wahl des Dezimalzeichens für
- Oxidationszahlen wie \ox{1.2,X}. Default = \code{point}
- \option[ox]{align}{center|right} Die Oxidationszahl über dem Atom zentrieren oder
- es mit diesem rechts ausrichten. Default = \code{center}
-\end{beschreibung}
-
-\begin{beispiel}
- \ox[roman=false]{2,Ca} \ox{2,Ca} \\
- \ox[pos=super]{3,Fe}-Oxid \\
- \ox[pos=side]{3,Fe}-Oxid \\
- \ox[parse=false]{?,Mn} \\
- \ox[align=right]{2,Ca}
-\end{beispiel}
-
-Die \key[ox]{pos}{super}-Variante kann auch mit dem Shortcut \cmd[oxa]{ox*} erzeugt
-werden:
-\begin{beispiel}
- \ox{3,Fe} \ox*{3,Fe}
-\end{beispiel}
-
-Die Verwenden von \key[ox]{explicit-sign} wird immer das Vorzeichen der Oxidationszahl
-zeigen:
-\begin{beispiel}
- \chemsetup[ox]{explicit-sign = true}
- \ox{+1,Na}, \ox{2,Ca}, \ox{-2,S}, \ch{"\ox{0,F}" {}2}
-\end{beispiel}
-
-\begin{beispiel}
- Vergleichen Sie \ox{-1,\ch{O2^2-}} mit \ch{"\ox{-1,O}" {}2^2-}
-\end{beispiel}
-
-Manchmal muss man formale Oxidationszahlen wie \num{.5} oder $\frac{1}{3}$ verwenden:
-\begin{beispiel}
- \ox{.5,\ch{Br2}} \ch{"\ox{1/3,I}" {}3+}
-\end{beispiel}
-
-Der Bruch verwendet den \lstinline+\sfrac+-Befehl des \paket{xfrac}-Pakets. Zu
-diesem Zweck wurde die Instanz \lstinline+chemmacros-ox-frac+ definiert.
-\begin{beispiel}[code only]
-\DeclareInstance{xfrac}{chemmacros-ox-frac}{text}
- {
- scale-factor = 1.2 ,
- denominator-bot-sep = -.5ex ,
- numerator-top-sep = -.3ex ,
- slash-left-kern = -.2em ,
- slash-right-kern = -.2em ,
- slash-symbol-font = lmr
- }

-\cmd{OX} setzt \code{<atom>} in einen Knoten (eine \enquote{Node}) mit dem Namen
-\code{<name>}. Wenn Sie zwei \cmd{OX} verwendet haben, dann können sie mit
-\cmd{redox} verbunden werden. Die Namen der zu verbindenden Knoten werden in runde
-Klammern geschrieben. Da \cmd{redox} ein Tikzpicture mit den Optionen \code{remember
-picture,overlay} erstellt, muss das Dokument \emph{wenigstens zwei mal} kompiliert
-werden.
-\begin{beispiel}[dist]
- \OX{a,Na} $\rightarrow$ \OX{b,Na}\pch\redox(a,b){oxidation}
-\end{beispiel}

-\begin{beispiel}[dist]
- \OX{a,Na} $\rightarrow$ \OX{b,Na}\pch\redox(a,b)[->,red]{ox}
-\end{beispiel}
-
-Mit dem Argument \oa{<num>} kann die Länge der vertikalen Linien angepasst werden.
-Die Voreinstellung beträgt \code{.6em}. Diese Länge wird mit \code{<num>}
-multipliziert. Ein negativer Wert wird die Linie \emph{unter} den Text setzen.
-\begin{beispiel}[dist]
- \OX{a,Na} $\rightarrow$ \OX{b,Na}\pch
- \redox(a,b)[->,red]{ox}
- \redox(a,b)[<-,blue][-1]{red}

-\begin{beschreibung}
- \Befehl{Enthalpy}[<options>]\da{<subscript>}\ma{<value>}
- \Befehl{Entropy}[<options>]\da{<subscript>}\ma{<value>}
- \Befehl{Gibbs}[<options>]\da{<subscript>}\ma{<value>}
-\end{beschreibung}
-
-Ihre Verwendung ist ziemlich selbsterklärend:
-\begin{beispiel}
- \Enthalpy{123} \\
- \Entropy{123} \\
- \Gibbs{123}
-\end{beispiel}
-Das Argument \da{<subscript>} Fügt eine Tiefstellung zur Spezifizierung hinzu:
-\cmd{Enthalpy}(r){123} \Enthalpy(r){123}.
-
-Die Befehle können mit mehreren Optionen angepasst werden:
-\begin{beschreibung}
- \Option*{exponent}{<anything>}
- \Option*{delta}{<anything>|false}
- \Option*{subscript}{left|right}
- \Option*{unit}{<unit>}
-\end{beschreibung}
-
-Die Voreinstellung hängt vom jeweiligen Befehl ab:
-\begin{beispiel}
- \Enthalpy[unit=\kilo\joule]{-285} \\
- \Gibbs[delta=false]{0} \\
- \Entropy[delta=\Delta,exponent=]{56.7}
-\end{beispiel}
-
-Die Zahl und die Einheit werden entsprechend der Regeln für \paket{siunitx} gesetzt
-und hängen von dessen Einstellungen ab:
-\begin{beispiel}
- \Enthalpy{-1234.56e3} \\
- \sisetup{per-mode=symbol,exponent-product=\cdot,output-decimal-marker={,},group-four-digits=true}
- \Enthalpy{-1234.56e3}

-\subsubsection{Neue Größen definieren}
-Mit dem Befehl
-\begin{beschreibung}
- \Befehl{DeclareChemState}[<options>]{<name>}\ma{<symbol>}\ma{<unit>}
-\end{beschreibung}
-können neue Größen definiert werden.
-\begin{beispiel}
- \DeclareChemState{Helmholtz}{A}{\kilo\joule\per\mole}
- \DeclareChemState[subscript-left=false,exponent=]{ElPot}{E}{\volt}
- \Helmholtz{123.4} \\
- \ElPot{-1.1} \\
- \ElPot[exponent=0]($\ch{Sn}|\ch{Sn^2+}||\ch{Pb^2+}|\ch{Pb}$){0.01}
-\end{beispiel}
-
-Dieser Befehl hat fast die gleichen Optionen, wie die Größen selbst, mit denen die
-Voreinstellung für die neue Größe festgelegt werden können.
-\begin{beschreibung}
- \Option*{exponent}{<anything>}
- \Option*{delta}{<anything>|false}
- \Option*{subscript-left}{\default{true}|false}
- \Option*{subscript}{<anything>}
-\end{beschreibung}
-
-\subsubsection{Größen umdefinieren}
-Mit
-\begin{beschreibung}
- \Befehl{RenewChemState}[<options>]{<name>}\ma{<symbol>}\ma{<unit>}
-\end{beschreibung}
-kann man bestehende Größen umdefinieren:
-
-\begin{beispiel}
- \RenewChemState{Enthalpy}{h}{\joule}
- \Enthalpy(f){12.5}
-\end{beispiel}
-Der Befehl ist analog zu \cmd{DeclareChemState}, \dh er hat dieselben Optionen.
-
-Man könnte also \textendash\ um thermodynamischen Konventionen zu folgen \textendash\
-eine molare und eine absolute Größe definieren:
-\begin{beispiel}
- \DeclareChemState[exponent=]{enthalpy}{h}{\kilo\joule\per\mole}% molar
- \RenewChemState[exponent=]{Enthalpy}{H}{\kilo\joule}% absolute
- \enthalpy{-12.3} \Enthalpy{-12.3}
-\end{beispiel}
-
-\subsection{Zustandsgrößen}\label{ssec:state}

-\begin{beschreibung}
- \Befehl{State}[<options>]{<symbol>}\ma{<subscript>}
-\end{beschreibung}
-Er kann verwendet werden, um die Größen ohne Wert und Einheit zu schreiben.

-\section{Spektroskopie und Messdaten}\label{sec:spektroskopie}\secidx{Spektroskopie}
-\subsection{Der \code{\textbackslash\textcolor{code}{NMR}}-Befehl}
-Wenn Substanzen darauf untersucht werden, ob sie sind, was sie sein sollen, wird
-oft die NMR Spektroskopie eingesetzt. Die Messergebnisse werden dann etwa so
-aufgeschrieben:
-\begin{center}
- \NMR(400)[CDCl3] = \num{1.59}
-\end{center}
-\chemmacros stellt einen Befehl zur Verfügung, der das vereinfacht (verwendet
-\paket{siunitx}).
-
-\begin{beschreibung}
- \Befehl{NMR}{<num>,<elem>}\da{<num>,<unit>}\oa{<solvent>}
- \Befehl{NMR*}{<num>,<elem>}\da{<num>,<unit>}\oa{<solvent>}
-\end{beschreibung}
-
-\emph{Alle} Argumente sind optional! Ohne Argumente\footnote{Alle Argumente können
-beliebig kombiniert werden.Der Befehl kann auch im Mathematik-Modus eingesetzt
-werden.} erhalten wir:
-\begin{beispiel}
- \NMR \\
- \NMR*
-\end{beispiel}
-
-Das erste Argument spezifiziert die Art der NMR:
-\begin{beispiel}
- \NMR{13,C}
-\end{beispiel}
-
-Mit dem zweiten Argument kann die verwendete Frequenz (in \si{\mega\hertz})
-angegeben werden:
-\begin{beispiel}
- \NMR(400)
-\end{beispiel}
-Auch mit Einheit:
-\begin{beispiel}
- \NMR(4e8,\hertz)
-\end{beispiel}
-Bitte beachten Sie, dass das Setup von \paket{siunitx} sich auch auf diesen
-Befehl auswirkt:
-\begin{beispiel}
- \sisetup{exponent-product=\cdot}\NMR(4e8,\hertz)
-\end{beispiel}
-
-Mit dem dritten Befehl schließlich kann das Lösungsmittel angegeben werden:
-\begin{beispiel}
- \NMR[CDCl3]
-\end{beispiel}
-
-\subsection{Abkürzungen}
-Da man verschiedene Kerne in einem Dokument eventuell häufiger benötigt, bietet
-\chemmacros eine Möglichkeit, Abkürzungen zu definieren.
-\begin{beschreibung}
- \Befehl{DeclareChemNMR}{<csname>}\ma{<num>,<atom>}
- \Befehl{RenewChemNMR}{<csname>}\ma{<num>,<atom>}
-\end{beschreibung}
-Das definiert einen Befehl mit denselben Argumenten wie \cmd{NMR}, \emph{außer} \ma{<num>,<atom>}.
-\begin{beispiel}
- \DeclareChemNMR\HNMR{1,H}%
- \DeclareChemNMR\CNMR{13,C}%
- \CNMR*(100) \\
- \HNMR*(400)
-\end{beispiel}
-
-\subsection{Eine Umgebung, um Messergebnisse darzustellen}
-Um ein bequemes Eingeben von Messergebnissen zu ermöglichen, bietet \chemmacros
-eine Umgebung.
-\begin{beschreibung}\catcode`\#=11
- \umg{experimental}{Daten} Umgebung für die Ausgabe von Ex\-pe\-ri\-men\-tal-Daten.
- Innerhalb dieser Umgebung sind die folgenden Befehle definiert.
- \Befehl{data}{<Typ>}\oa{<Spezifikation>} \cnpkgdocarrow\ Typ der Daten, \zB\ IR,
- MS\ldots\ In das optionale Argument können weitere Spezifikationen eingegeben
- werden, die in runden Klammern ausgegeben werden.
- \Befehl{data*}{<Typ>}\oa{<Spezifikation>} \cnpkgdocarrow\ Wie \cmd{data}, gibt
- aber anstelle des \code{=} ein \code{:} mit aus, wenn \key{use-equal}{true}
- eingestellt ist.
- \Befehl{NMR}{<num>,<elem>\oa{<coupling core>}}\da{<num>,<unit>}\oa{<solvent>}
- \cnpkgdocarrow\ der Befehl bekommt ein weiteres Argument:
- \cmd{NMR}{13,C[\textasciicircum 1H]} \NMR{13,C[^1H]}
- \Befehl{J}\da{<bonds>;<nuclei>}\oa{<unit>}\ma{<list of nums>} \cnpkgdocarrow\
- Kopplungskonstante, Werte werden mit \code{;} getrennt eingegeben. Für NMR.
- Das Argument \da{<bonds>;<nuclei>} ist optional und ermöglicht die Angabe von
- genaueren Spezifikationen der Kopplung.
- \befehl{#}{<num>} Anzahl der Kerne. Für NMR.
- \befehl{pos}{<num>} Position/Nummer des Kerns. Für NMR.
- \befehl{val}{<num>} Zahlenwert, ein Alias für \paket*{siunitx}'
- \lstinline+\num{<num>}+
- \befehl{val}{<num1>-{}-<num2>} Ein Alias für \paket*{siunitx}'
- \lstinline+\numrange{<num1>}{<num2>}+
-\end{beschreibung}
-
-\begin{beispiel}
- \begin{experimental}
- \data{Typ1} Daten.
- \data{Typ2}[Spezifikationen] noch mehr Daten.
- \data*{Typ3} weitere Daten.
- \end{experimental}
-\end{beispiel}
-
-\subsection{Anpassung}
-Die Ausgabe der Umgebung und der NMR-Befehle kann mir einer Reihe Optionen angepasst
-werden. Aus historischen Gründen gehören sie dem Modul \textcolor{module}{\code{nmr}}
-an.
-\begin{beschreibung}
- \option[nmr]{unit}{<unit>} Default = \lstinline=\mega\hertz=
- \option[nmr]{nucleus}{\{<num>,<atom>\}} Default = \ma{1,H}
- \option[nmr]{format}{<commands>} zum Beispiel \lstinline=\bfseries=
- \option[nmr]{pos-number}{side|sub} Position der Zahl neben dem Atom. Default =
- \code{side}
- \option[nmr]{coupling-unit}{<unit>} Eine \paket{siunitx} Einheit. Default =
- \lstinline=\hertz=
- \option[nmr]{parse}{\default{true}|false} Das Lösungsmittel als \paket{mhchem}/\chemformula-Formel
- behandeln oder nicht. Default = \code{true}
- \option[nmr]{delta}{<tokens>} Die \code{<tokens>} werden nach $\delta$ eingefügt.
- \option[nmr]{list}{\default{true}|false} Die Umgebung \env{nmr}[<optionen>]{} wird als
- Liste formatiert. Default = \code{false}
- \option[nmr]{list-setup}{<setup>} Setup der Liste. Default = siehe unten.
- \option[nmr]{use-equal}{\default{true}|false} Istgleich-Zeichen nach \cmd{NMR}
- und \cmd{data} einsetzen. Default = \code{false}
-\end{beschreibung}
-
-Das Default-Setup der Liste:
-\begin{beispiel}[code only]
- \topsep\z@skip \partopsep\z@skip
- \itemsep\z@ \parsep\z@ \itemindent\z@
- \leftmargin\z@
-\end{beispiel}
-
-\begin{beispiel}
- \begin{experimental}[format=\bfseries]
- \data{Typ1} Daten.
- \data{Typ2}[Spezifikationen] noch mehr Daten.
- \data*{Typ3} weitere Daten.
- \end{experimental}
-\end{beispiel}
-
-Der Befehl \cmd{NMR} und alle mit \cmd{DeclareChemNMR} definierten Befehle können
-anstelle von \cmd{data} für NMR-Daten eingesetzt werden.
-
-\begin{beispiel}
- \begin{experimental}[format=\bfseries,use-equal]
- \data{Typ1} Daten.
- \data{Typ2}[Spezifikationen] noch mehr Daten.
- \NMR weitere Daten.
- \end{experimental}
-\end{beispiel}

-\section{Reaktionsumgebungen}\label{sec:reactions}\secidx{Reaktionsumgebungen}
-\subsection{Durch \chemmacros definiert}
-Es stehen folgende Umgebungen für nummerierte\ldots
-\begin{beschreibung}
- \Umg{reaction}{<formula or mhchem code>}
- \Umg{reactions}{<formula or mhchem code>}
-\end{beschreibung}
-
-\ldots und ihre gesternten Versionen für unnummerierte Reaktionen zur Verfügung.
-\begin{beschreibung}
- \Umg{reaction*}{<formula or mhchem code>}
- \Umg{reactions*}{<formula or mhchem code>}
-\end{beschreibung}
-Damit können Sie (un-) nummerierte Reaktionsgleichungen erstellen ähnlich den
-mathematischen Gleichungen.
-
-Die Umgebungen \code{reaction}/\code{reaction*} verwenden intern \code{equation}/\code{equation*}
-Umgebungen und die Umgebungen \code{reactions}/\code{reactions*} verwenden die
-\code{align}/\code{align*} Umgebungen, um die Reaktionen darzustellen.
-
-\begin{beispiel}
- Reaktion mit Z\"ahler:
- \begin{reaction}
- A -> B
- \end{reaction}
-\end{beispiel}
-
-\begin{beispiel}
- Reaktion ohne Z\"ahler:
- \begin{reaction*}
- C -> D
- \end{reaction*}
-\end{beispiel}
-
-\begin{beispiel}
- mehrere ausgerichtete Reaktionen mit Z\"ahler:
- \begin{reactions}
- A &-> B + C \\
- D + E &-> F
- \end{reactions}
-\end{beispiel}
-
-\begin{beispiel}
- mehrere ausgerichtete Reaktionen ohne Z\"ahler:
- \begin{reactions*}
- G &-> H + I \\
- J + K &-> L
- \end{reactions*}
-\end{beispiel}
-
-Wenn Sie das Layout der Zähler-Tags ändern wollen, verwenden Sie
-\begin{beschreibung}
- \Befehl{renewtagform}{<tagname>}\oa{<format>}\ma{<right delim>}\ma{<left delim>}%
- \footnote{Durch das \paket*{mathtools} Paket zur Verfügung gestellt.}.
-\end{beschreibung}
-
-\begin{beispiel}
- \renewtagform{reaction}[R \textbf]{[}{]}
- \begin{reaction}
- H2O + CO2 <<=> H2CO3
- \end{reaction}
-\end{beispiel}
-
-Seit Version 3.3 funktionieren Querverweise und \AmS maths \cmd{intertext} wie
-erwartet:
-\begin{beispiel}
- \begin{reactions}
- A + 2 B &-> 3 C + D \label{rxn:test}
- \intertext{Etwas Text zwischen ausgerichteten Reaktionen.}
- 3 E + F &<=> G + 1/2 H
- \end{reactions}
- Siehe Reaktion \ref{rxn:test}.
-\end{beispiel}
-
-\achtung{In der Standardeinstellung, \dh mit \key{method}{chemformula}, sollten
-Sie \cmd{mch} und die verwandten Befehle innerhalb der \code{reaction} Umgebungen
-nicht verwenden. Sie bringen in den meisten Fällen die korrekte Ausrichtung
-durcheinander. In der Standardeinstellung erkennen Ladungen in den Umgebungen
-die Einstellung der Option \key{circled} automatisch, so dass die Befehle auch
-nicht benötigt werden.}
-
-\subsection{Eigene Reaktionen}
-Sie können mit dem Befehl
-\begin{beschreibung}
- \Befehl{DeclareChemReaction}[<options>]{<name>}\ma{<math name>}
-\end{beschreibung}
-weitere Reaktionsumgebungen erstellen.
-
-\code{<name>} wird der Name der neuen Umgebung sein. \code{<math name>} ist die
-verwendete Mathematikumgebung.
-
-Der Befehl hat zwei Optionen.
-\begin{beschreibung}
- \Option*{star}{\default{true}|false}
- \Option*{arg}{\default{true}|false}
-\end{beschreibung}
-Zum einen \key*{star}, die auch die gesternte Variante definiert, vorausgesetzt,
-die entsprechende Mathematikumgebung existiert. Falls nicht, wird es einen Fehler
-geben.
-
-Dann gibt es \key*{arg}, die verwendet wird, um eine Umgebung mit einem obligatorischen
-Argument zu erstellen. Auch das funktioniert natürlich nur, wenn die entsprechende
-Mathematikumgebung ebenfalls ein obligatorisches Argument besitzt.
-
-Die vordefinierten Umgebungen wurden durch
-\begin{beschreibung}
- \Befehl{DeclareChemReaction}[star]{reaction}\ma{equation} und
- \Befehl{DeclareChemReaction}[star]{reactions}\ma{align}.
-\end{beschreibung}
-definiert.
-
-Nehmen wir an, Sie wollen eine Umgebung mit dem Verhalten der \code{alignat} Umgebung
-für \chemformula-/\paket{mhchem}-Reaktionen. Sie könnten folgendes tun:
-\begin{beispiel}[code only]
- \DeclareChemReaction[star,arg]{reactionsat}{alignat}
-\end{beispiel}
-
-Damit ist die \code{reactionsat}-Umgebung definiert.
-\begin{beispiel}
- \DeclareChemReaction[star,arg]{reactionsat}{alignat}
- \begin{reactionsat}{3}
- A &-> B &&-> C &&-> D \\
- aaaaa &-> bbbbb &&-> ccccc &&-> ddddd
- \end{reactionsat}
- \begin{reactionsat*}{2}
- A &-> B & C &-> D \\
- aaaaa &-> bbbbb &\quad{} ccccc &-> ddddd
- \end{reactionsat*}
-\end{beispiel}
-
-\subsection{Liste der Reaktionen}
-\chemmacros stellt ebenso einen Befehl zur Verfügung, mit dem man eine Liste der
-Reaktionen ausgeben kann, die mit den Reaktionsumgebungen eingegeben wurden.
-\begin{beschreibung}
- \Befehl{listofreactions}
-\end{beschreibung}
-\begin{beispiel}[below]
- \listofreactions
-\end{beispiel}
-
-Der Output kann mit den folgenden Optionen angepasst werden:
-\begin{beschreibung}
- \option[reaction]{list-name}{<name of the list>} Setzen der Listenüberschrift.
- Default = \code{Reaktionsverzeichnis}
- \option[reaction]{list-entry}{<prefix to each entry>} Präfix zu jedem Eintrag.
- Default = \code{Reaktion}
-\end{beschreibung}
-Beide Default-Werte reagieren auf die Option \key[option]{german}.
-
-Statt die Option \key{list-name} zu verwenden, könnten Sie auch \cmd{reactionlistname}
-umdefinieren.
-
-Im Verzeichnis werden alle Reaktionen mit Zählen gelistet und alle anderen nicht
-aufgenommen. Alle Reaktionsumgebungen ohne Stern haben ein optionales Argument,
-mit dem man eine Beschreibung für die Liste hinzufügen kann.
-\begin{beispiel}
- \begin{reaction}[Autoprotolyse]
- 2 H2O <<=> H3O+ + OH-
- \end{reaction}
-\end{beispiel}
-Wenn Sie die \code{reactions} Umgebung verwenden, wird das allerdings nicht
-funktionieren. In diesem Fall können Sie
-\begin{beschreibung}
- \Befehl{AddRxnDesc}{<description>}
-\end{beschreibung}
-verwenden.
-\begin{beispiel}
- \begin{reactions}
- Cl "\Lewis{0.,\vphantom{Cl}}" + CH4 &-> HCl + "\Lewis{4.,\vphantom{CH}}" CH3 \AddRxnDesc{first~step~of~chain} \\
- "\Lewis{4.,\vphantom{CH}}" CH3 + Cl2 &-> CH3Cl + Cl "\Lewis{0.,\vphantom{Cl}}" \AddRxnDesc{second~step~of~chain}
- \end{reactions}
-\end{beispiel}
-Nebenbei: Sie müssen die Phantom-Befehle nicht verwenden, wenn Sie das Format der
-Atome nicht geändert haben, siehe Abschnitt~\ref{sec:format} an Seite~\pageref{sec:format}.
-\secidx*{Reaktionsumgebungen}

-\section{Phasen}\label{sec:phasen}\secidx{Phasen}
-\subsection{Grundlagen}\secidx[Grundlagen]{Phasen}
-Diese Befehle sollen helfen, die Phase einer Substanz anzuzeigen.
-\begin{beschreibung}
- \befehl{sld} \sld
- \befehl{lqd} \lqd
- \befehl{gas} \gas
- \befehl{aq} \aq
-\end{beschreibung}
-
-\achtung{Das Default-Verhalten der Phasen-Befehle hat sich geändert, um der
-\ac{iupac}-Empfehlung zu folgen. Sowohl \cmd{sld} als auch \cmd{lqd} haben kein
-optionales Argument mehr.}
-
-\begin{beispiel}
- \ch{C\sld{} + 2 H2O\lqd{} -> CO2\gas{} + 2 H2\gas}\\
- der Vollst\"andigkeit halber: NaCl\aq.
-\end{beispiel}
-
-Mit der Paketoption \key{language}{english} (siehe Abschnitt~\ref{sec:optionen})
-erhalten Sie die englischen Versionen.
-
-Die \ac{iupac}-Empfehlung\footnote{Vielen Dank an Paul King für den Hinweis.} um einen
-Aggregatszustand anzuzeigen ist es, sie in Klammern nach der Formel zu
-schreiben~\cite{iupac:greenbook}. Es ist jedoch ebenfalls verbreitet, sie als
-Tiefstellung zu setzen.
-
-\begin{zitat}[{\ac{iupac} Green Book {\cite[][p.\,54]{iupac:greenbook}}}]
- The \textelp{} symbols are used to represent the states of aggregation of chemical
- species. The letters are appended to the formula in parentheses and should be
- printed in Roman (upright) type without a full stop (period).
-\end{zitat}
-
-Es gibt zwei Optionen, um den Output anzupassen:
-\begin{beschreibung}
- \option[phases]{pos}{side|sub} Umschalten der Position des Phasen-Anzeigers.
- Default = \code{side}
- \option[phases]{space}{<dim>} Ändern des Zwischenraums zwischen Formel und dem
- Phasen-Anzeiger bei \key{pos}{side}. Eine \TeX-Dimension. Default = \code{.1333em}
-\end{beschreibung}
-\begin{beispiel}
- \chemsetup[phases]{pos=sub}

-\end{beispiel}
-
-\subsection{Eigene Phasen definieren}\secidx[eigene]{Phasen}
-Abhängig vom Thema ihres Dokuments müssen Sie unter Umständen andere Aggregatszustände
-anzeigen. Sie können Sie einfach definieren.
-\begin{beschreibung}
- \Befehl{DeclareChemPhase}{<cmd>}\oa{<german>}\ma{<english>}
- \Befehl{RenewChemPhase}{<cmd>}\oa{<german>}\ma{<english>}
- \befehl{phase}{<phase>} Wenn Sie die Phase nur ein- oder zweimal verwenden müssen.
-\end{beschreibung}
-\cmd{DeclareChemPhase} definiert die Phase nur dann, wenn \code{<cmd>} noch nicht
-existiert. Andernfalls wird \chemmacros entweder eine Warnung oder einen Fehler
-ausgeben, abhängig vob der Option \key{strict}. \cmd{RenewChemParticle} definiert
-eine Phase \emph{nur}, wenn \code{<cmd>} schon existiert und gibt andernfalls eine
-Warnung/einen Fehler.
-\begin{beispiel}
- \DeclareChemPhase{\aqi}{aq,$\infty$}% aqueous solution at infinite dilution
- \DeclareChemPhase{\cd}{cd}% condensed phase
- \RenewChemPhase{\lqd}{lc}% liquid crystal
- NaOH\aqi\ \ch{H2O\cd} U\phase{cr} A\lqd \\

-\section{Newman-Projektionen}\label{sec:newman}\secidx{Newman-Projektionen}
-\chemmacros stellt den Befehl
-\begin{beschreibung}
- \Befehl{newman}[<options>]\da{<angle>}\ma{<1>,<2>,<3>,<4>,<5>,<6>}
-\end{beschreibung}
-zur Verfügung, der Ihnen erlaubt, Newman-Projektionen zu erstellen (verwendet \TikZ).
-Das Argument \da{<angle>} dreht die hinteren Atome gegen den Uhrzeigersinn bezüglich
-der vorderen Atome.
-\begin{beispiel}
- \newman{} \newman(170){}
- \newman{1,2,3,4,5,6} \newman{1,2,3} \newman{,,,4,5,6}
-\end{beispiel}
-
-Es gibt einige Optionen, um den Befehl anzupassen:
-\begin{beschreibung}
- \option[newman]{angle}{<angle>} Voreingestellter Winkel. Default = \code{0}
- \option[newman]{scale}{<factor>} Skaliert die ganze Projektion. Default = \code{1}
- \option[newman]{ring}{<tikz>} Aussehen des Rings mit \TikZ-Keys anpassen.
- \option[newman]{atoms}{<tikz>} Aussehen der Knoten, in die die Atome geschrieben
- werden, mit \TikZ-Keys anpassen.
- \option[newman]{back-atoms}{<tikz>} Nur die hinteren Atome anpassen.

-\section{s, p und Hybrid-Orbitale}\label{sec:orbitale}\secidx{Orbitale}
-\chemmacros stellt einen Befehl bereit, mit dem Orbitale visualisiert werden können:
-\begin{beschreibung}
- \Befehl{orbital}[<options>]{<type}
-\end{beschreibung}
-
-Dabei stehen folgende Typen für \ma{<type>} zur Verfügung:
-\begin{description}
- \item \code{s}
- \item \code{p}
- \item \code{sp}
- \item \code{sp2}
- \item \code{sp3}
-\end{description}
-
-\begin{beispiel}
- \orbital{s} \orbital{p} \orbital{sp} \orbital{sp2} \orbital{sp3}
-\end{beispiel}
-
-Abhängig vom Typ stehen verschiedene Optionen zur Modifikation zur Auswahl:
-\begin{beschreibung}
- \option[orbital]{phase}{\default{+}|-} Ändern der Phase des Orbitals (alle Typen).
- \option[orbital]{scale}{<factor>} Ändern der Größe des Orbitals (alle Typen).
- \option[orbital]{color}{<color>} Ändern der Farbe des Orbitale (alle Typen).
- \option[orbital]{angle}{<angle>} Rotiert die Orbitale mit einem p-Anteil gegen
- den Uhrzeigersinn (alle Typen außer \code{s}).
- \option[orbital]{half}{\default{true}|false} stellt nur ein halbes Orbital dar
- (nur \code{p}).
-\end{beschreibung}
-
-\begin{beispiel}
- \orbital{s} \orbital[phase=-]{s}
- \orbital{p} \orbital[phase=-]{p}
- \orbital{sp3} \orbital[phase=-]{sp3}
-
- \orbital[angle=0]{p} \orbital[color=red!50]{p} \orbital[angle=135,scale=1.5]{p} \orbital[half]{p}
-\end{beispiel}
-
-Zusätzlich gibt es zwei Optionen, mit denen das \TikZ-Verhalten beeinflusst werden
-kann:
-\begin{beschreibung}
- \option[orbital]{overlay}{\default{true}|false} Das Orbital „braucht keinen Platz”;
- es wird mit dem \TikZ-Key \code{overlay} gezeichnet.
- \option[orbital]{opacity}{<num>} Das Orbital wird durchsichtig; \code{<value>}
- kann Werte zwischen \code{1} (undurchsichtig) bis \code{0} (unsichtbar) annehmen.

-}
-\section{Setup}
-Alle Optionen von \chemformula gehören dem Modul \textcolor{module}{\code{chemformula}}
-an. Das bedeutet, sie können via
-\begin{beispiel}[code only]
- \chemsetup[chemformula]{<options>} oder
- \chemsetup{chemformula/<option1>,chemformula/<option2>}
-\end{beispiel}
-eingestellt werden.
-
-Sie können außerdem direkt als Option an den Befehl \cmd{ch} weitergegeben werden.
-
-\section{Das Grundprinzip}
-\chemformula hat einen Hauptbefehl.
-\begin{beschreibung}
- \Befehl{ch}[<options>]{<input>}
-\end{beschreibung}
-
-Die Verwendung wird Ihnen sehr vertraut vorkommen, wenn Ihnen \paket{mhchem}
-geläufig ist:
-\begin{beispiel}
- \ch{H2O} \\
- \ch{Sb2O3} \\
- \ch{H+} \\
- \ch{CrO4^2-} \\
- \ch{AgCl2-} \\
- \ch{[AgCl2]-} \\
- \ch{Y^{99}+} \\
- \ch{Y^{99+}} \\
- \ch{H2_{(aq)}} \\
- \ch{NO3-} \\
- \ch{(NH4)2S} \\
- \ch{^{227}_{90}Th+} \\
- $V_{\ch{H2O}}$ \\
- \ch{Ce^{IV}} \\
- \ch{KCr(SO4)2 * 12 H2O}
-\end{beispiel}
-
-Es gibt jedoch Unterschiede. Der wichtigste: \chemformula unterscheidet zwischen
-verschiedenen Input-Typen. Diese verschiedenen Typen \emph{müssen} durch Leerzeichen
-getrennt eingegeben werden:
-\begin{beschreibung}
- \Befehl{ch}{type1 type2 type3 type4}
-\end{beschreibung}
-
-Ein Leerzeichen im Input ist \emph{niemals} ein Leerzeichen im Output. Die Rolle
-des Leerzeichens gilt strikt und kann zu Fehlern oder fehlerhaften Output führen,
-wenn sie nicht beachtet wird.
-
-Ein weiterer wichtiger Unterschied: \chemformula versucht, den Mathematikmodus
-weitestgehend zu vermeiden:
-\begin{beispiel}
- \ch{A + B ->[a] C} \\
- \ce{A + B ->[a] C}
-\end{beispiel}
-
-Der erste Punkt bedeutet, dass \cmd{ch}{2H2O} als \emph{ein} Teil behandelt wird,
-in diesem Fall als Summenformel.
-\begin{beispiel}
- \ch{2H2O} \\
- \ch{2 H2O}
-\end{beispiel}
-Das bedeutet außerdem, dass ein Teil kein Leerzeichen enthalten kann, da ein
-Leerzeichen ihn automatisch in zwei Teile teilen würde. Wenn Sie ein Leerzeichen
-im Output benötigen, müssen sie ein \lstinline+~+ eingeben. Da die meisten Makros
-ein folgendes Leerzeichen schlucken, wird jedoch ein Input wie \cmd{ch}{\textbackslash
-command ABC} als einzelner Teil behandelt. Wenn Sie einen solchen Input teilen wollen,
-müssen Sie eine leere Gruppe eingeben: \cmd{ch}{\textbackslash command\{\} ABC}.
-Die verschiedenen Input-Typen werden in den folgenden Abschnitten einzeln behandelt.
-
-Der \cmd{ch}-Befehl hat einige Optionen, mit denen der Output verändert werden kann.
-Sie können entweder lokal als optionales Argument oder global mit dem Befehl
-\begin{beschreibung}
- \Befehl{chemsetup}[chemformula]{<options>}
-\end{beschreibung}
-gesetzt werden. Alle Optionen von \chemformula gehören dem Modul
-\textcolor{module}{\code{chemformula}} an.
-
-\section{Stöchiometrische Faktoren}\secidx{Stöchiometrische Faktoren}[Stoechiometrische Faktoren]
-Ein stöchiometrischer Faktor darf nur aus Ziffern und den Zeichen \lstinline+.,_/()+
-bestehen.
-\begin{beispiel}
- \ch{2} \\
- \ch{12}
-
- % decimals:
- \ch{.5} \\
- \ch{5,75}
-
- % fractions:
- \ch{3/2} \\
- \ch{1_1/2}
-
- % ``iupac'':
- \ch{(1/2)}
-\end{beispiel}
-
-Wie Sie sehen können, wird bei Dezimalbrüchen eine führende Null ergänzt, wenn
-sie in der Eingabe fehlt.
-
-Sie müssen bei dem Input ein wenig auf die richtige Syntax achten, aber ich denke,
-sie ist recht intuitiv.
-\begin{beispiel}[code only]
- das wird nicht funktionieren sondern einen Fehler geben: \ch{1/1_1}
-\end{beispiel}
-
-Wenn die stöchiometrischen Faktoren in Klammern geschrieben werden, werden die Brüche
-nicht umgewandelt und führende Nullen nicht ergänzt. Was in den Klammern steht,
-wird genauso geschrieben.
-\begin{beispiel}
- \ch{(1/2) H2O} \ch{1/2 H2O} \ch{0.5 H2O}
-\end{beispiel}
-Viele Beispiele wie das folgende für die Verwendung von Klammern um stöchiometrische
-Faktoren finden Sie \zB im „\ac{iupac} Green Book“ \cite{iupac:greenbook}:
-\begin{reaction*}
- (1/5) K "\ox*{7,Mn}" O4 + (8/5) HCl == (1/5) "\ox*{2,Mn}" Cl2 + (1/2) Cl2 + (1/5) KCl + (4/5) H2O
-\end{reaction*}
-
-Der Output kann mit diesen Optionen angepasst werden:
-\begin{beschreibung}
- \option{decimal-marker}{<marker>} Das Symbol, das als Dezimalzeichen verwendet
- wird. Default = \code{.}
- \option{frac-style}{math|xfrac|nicefrac} Bestimmt, wie Brüche dargestellt werden.
- Default = \code{math}
- \option{stoich-space}{<skip>} Der Leerraum nach einem stöchiometrischen Faktor.
- Eine elastische Länge. Default = \code{.1667em plus .0333em minus .0117em}
- \option{stoich-paren-parse}{\default{true}|false} Wenn die Option auf
- \code{true} gesetzt ist, werden auch stöchiometrische Faktoren, die in Klammern
- stehen, verarbeitet, d.h. Brüche umgewandelt und führende Nullen ergänzt.
- Default = \code{false}
-\end{beschreibung}
-\begin{beispiel}
- \ch[decimal-marker={,}]{3.5} \ch[decimal-marker={$\cdot$}]{3,5}
-\end{beispiel}
-
-Die Option \key{frac-style}{xfrac} verwendet den Befehl \lstinline+\sfrac+ des
-\paket{xfrac}-Pakets. Der Output kann sehr von der gewählten Schrift abhängen.
-\secidx[xfrac]{Stöchiometrische Faktoren}[Stoechiometrische Faktoren]
-\begin{beispiel}
- \ch[frac-style=xfrac]{3/2} \ch[frac-style=xfrac]{1_1/2}
-\end{beispiel}
-
-\chemformula definiert die Instanz \lstinline=formula-text-frac=, die nach dem
-eigenen Bedarf umdefiniert werden kann. Default ist folgendes:
-\begin{beispiel}[code only]
- \DeclareInstance{xfrac}{chemformula-text-frac}{text}
- {
- slash-left-kern = -.15em ,
- slash-right-kern = -.15em
- }
-\end{beispiel}
-Dieses Dokument verwendet den Font Linux Libertine~O und folgende Definition:
-\begin{beispiel}[code only]
- \DeclareInstance{xfrac}{chemformula-text-frac}{text}
- {
- scale-factor = 1 ,
- denominator-bot-sep = -.2ex ,
- denominator-format = \scriptsize #1 ,
- numerator-top-sep = -.2ex ,
- numerator-format = \scriptsize #1 ,
- slash-right-kern = .05em ,
- slash-left-kern = .05em
- }
-\end{beispiel}
-
-Die Option \key{frac-style}{nicefrac} verwendet den Befehl \lstinline+\nicefrac+
-des \paket{nicefrac}-Pakets.\secidx[nicefrac]{Stöchiometrische Faktoren}[Stoechiometrische Faktoren]
-\begin{beispiel}
- \ch[frac-style=nicefrac]{3/2} \ch[frac-style=nicefrac]{1_1/2}
-\end{beispiel}
-
-Die Option \key{stoich-space} erlaubt Ihnen, den Leerraum zwischen stöchiometrischem
-Faktor und Summenformel einzustellen.\secidx[space]{Stöchiometrische Faktoren}[Stoechiometrische Faktoren]
-\begin{beispiel}
- \ch{2 H2O} \\

-\section{Summenformeln}\label{ssec:compounds}\secidx{Summenformeln}
-\chemformula bestimmt Summenformeln als den Typ, der \enquote{nirgendwo sonst
-hineinpasst}. Das wird klarer werden, wenn Sie die anderen Typen kennen.
-\begin{beispiel}
- \ch{H2SO4} \\
- \ch{[Cu(NH3)4]^2+}
-\end{beispiel}
-
-\subsection{Addukte}\secidx[Addukte]{Summenformeln}
-\chemformula hat zwei Identifier, die Addukte erzeugen.
-\begin{beschreibung}
- \befehl{ch}{A.B} \ch{A.B}
- \befehl{ch}{A*B} \ch{A*B}
-\end{beschreibung}
-\begin{beispiel}
- \ch{CaSO4.H2O} \\
- \ch{CaSO4*H2O}
-\end{beispiel}
-Da Ziffern in einer Summenformel immer als Tiefstellung betrachtet werden (siehe
-Abschnitt~\ref{ssec:subscripts}), müssen Sie manchmal einen Leerraum lassen, damit
-der stöchiometrische Faktor korrekt erkannt wird:
-\begin{beispiel}
- \ch{Na3PO4*12H2O} \\
- \ch{Na3PO4* 12 H2O} \\
- \ch{Na3PO4 * 12 H2O}
-\end{beispiel}
-
-\subsection{Tiefstellungen}\label{ssec:subscripts}\secidx[Tiefstellungen]{Summenformeln}
-\emph{Alle} Ziffern in einer Substanz werden als Tiefstellung behandelt.
-\begin{beispiel}
- \ch{H2SO4}
-\end{beispiel}
-Wenn Sie einen Buchstaben als Tiefstellung möchten, verwenden Sie die Mathematik-Syntax:
-\begin{beispiel}
- \ch{A_nB_m}
-\end{beispiel}
-
-Die Tiefstellung erkennt Gruppen. Sie können darin auch Mathematikmodus verwenden.
-\begin{beispiel}
- \ch{A_{$n$}B_{$m$}} \\
- \ch{NaCl_{(aq)}}
-\end{beispiel}
-
-\subsection{Befehle}\secidx[Befehle]{Summenformeln}
-Befehle sind in einer Summenformel erlaubt:
-\begin{beispiel}
- \ch{\textbf{A2}B3} \ch{A2\color{red}B3}
-\end{beispiel}
-Wenn jedoch ein Befehl eine Ziffer als Argument benötigt, wie \zB Leerraum-Befehle
-oder der \lstinline+\ox+-Befehl, wird die direkte Verwendung schiefgehen. Das liegt
-daran, dass die Ziffern als Tiefstellung behandelt werden, \emph{bevor} der Befehl
-expandiert.
-\begin{beispiel}[code only]
- \ch{A\hspace{2mm}B} wird einen Fehler geben, da \hspace in etwa so etwas sieht: \hspace{$_2$mm}.
-\end{beispiel}

-\subsection{Ladungen und andere Hochstellungen}\secidx[Ladungen]{Summenformeln}\secidx[Hochstellungen]{Summenformeln}
-\paragraph{Grundlagen}
-Wenn eine Summenformel mit einem Plus- oder Minus-Zeichen \emph{endet}, wird es als
-Ladungssymbol interpretiert und hochgestellt. An anderen Stellen repräsentiert ein
-Plus eine Dreifachbindung und ein Dash eine Einfachbindung, siehe Abschnitt~\ref{ssec:bonds}.
-\begin{beispiel}
- \ch{A+B} \ch{AB+} \\
- \ch{A-B} \ch{AB-}
-\end{beispiel}
-
-Für längere Ladungsgruppen oder andere Hochstellungen können Sie die Mathematik-Syntax
-verwenden. Sie beachtet Gruppen und erlaubt Mathematik in ihnen. Innerhalb dieser
-Gruppen werden weder \code{+} noch \code{-} als Bindungen interpretiert. Wenn sich
-ein Punkt \code{.} in einer Hochstellung befindet, zeigt er kein Addukt an sondern
-ein Radikal. Ein \code{*} gibt den angeregten Zustand.
-\begin{beispiel}
- \ch{A^{x-}} \\
- \ch{A^x-} \\
- \ch{A^{x}-} \\
- \ch{A^{$x-$}} \\
- \ch{RNO2^{-.}} \\
- \ch{^31H} \\
- \ch{^{14}6C} \\
- \ch{^{58}_{26}Fe} \\
- \ch{NO^*}
-\end{beispiel}
-
-Ionen und Ionenverbindungen mit mehr als einer Ladung werden genauso eingegeben:
-\begin{beispiel}
- \ch{SO4^2-} \ch{Ca^2+ SO4^2-}
-\end{beispiel}
-
-\paragraph{Ladungsbefehle}\secidx[Hochstellungen!Ladungsbefehle]{Summenformeln}
-Man benötigt kein \cmd{mch} und ähnliche Befehle innerhalb von \cmd{ch}. Tatsächlich
-\emph{sollte man sie vermeiden}, da sie die Ausrichtung der Hoch- und Tiefstellungen
-durcheinander bringen können. Die \chemmacros-Option \code{circled} wird von \cmd{ch}
-beachtet.
-\begin{beispiel}
- \chemsetup[option]{circled=all}
- \ch{H+ + OH- <=> H2O}
-\end{beispiel}
-
-\paragraph{Verhalten}\secidx[Hochstellungen!Verhalten]{Summenformeln}
-Die Hochstellungen verhalten sich unterschiedlich abhängig von ihrer Position in
-einer Summenformel, falls Hoch- und Tiefstellung direkt aufeinander folgen.
-\begin{beispiel}
- \ch{^33B} \ch{{}^33B} \ch{3^3B} \ch{B^3} \ch{B3^3} \\
- \ch{^{23}_{123}B} \ch{{}^{23}_{123}B} \ch{_{123}^{23}B} \ch{B^{23}} \ch{B_{123}^{23}} \\
- \ch{^{123}_{23}B} \ch{{}^{123}_{23}B} \ch{_{23}^{123}B} \ch{B^{123}} \ch{B23^{123}}
-\end{beispiel}
-\begin{itemize}
- \item Wenn eine Formel mit einer Hochstellung \emph{startet}, werden Hoch- und
- Tiefstellung \emph{rechts} ausgerichtet, ansonsten \emph{links}.
- \item Wenn eine Hochstellung einer Tiefstellung \emph{folgt}, wird sie zusätzlich
- um eine Länge verschoben, die durch die Option \key{charge-hshift}{<dim>} bestimmt
- wird, siehe auch Seite~\pageref{desc:charge-hshift}f.
-\end{itemize}
-
-Der zweite Punkt folgt der \ac{iupac}-Empfehlung:
-\begin{zitat}[{\ac{iupac} Green Book {\cite[][p.\,51]{iupac:greenbook}}}]
- In writing the formula for a complex ion, spacing for charge number can be added
- (staggered arrangement), as well as parentheses: \ch[charge-hshift=1ex]{SO4^2-},
- \ch{(SO4)^2-} The staggered arrangement is now recommended.
-\end{zitat}

-\subsection{Bindungen}\label{ssec:bonds}\secidx[Bindungen]{Summenformeln}
-\subsubsection{Natürliche Bindungen}
-\chemformula kennt drei Sorten Bindungen, die ich \enquote{natürliche Bindungen}
-nennen werde:
-\begin{beispiel}
- einfach: \ch{CH3-CH3} \\
- doppel: \ch{CH2=CH2} \\
- dreifach: \ch{CH+CH}
-\end{beispiel}
-
-\subsubsection{Flexible Bindungen}
-\paragraph{Predefined Bindungen}
-Zusätzlich zu den drei natürlichen Bindungen gibt es ein paar weitere, die mit
-folgendem Befehl aufgerufen werden können:
-\begin{beschreibung}
- \Befehl{bond}{<bond name>}
-\end{beschreibung}
-Die vordefinierten Bindungstypen sind in Tabelle~\ref{tab:bond_types} aufgeführt.
-
-\begin{table}
- \centering
- \caption{Bindungen, die mit \protect\cmd{bond} aufgerufen werden können.}
- \label{tab:bond_types}
- \begin{tabular}{lcl}
- \toprule
- \bfseries Name & \bfseries Aussehen & \bfseries Aliase \\
- \midrule
- \code{single} & \bond{single} & \code{normal}, \code{sb} \\
- \code{double} & \bond{double} & \code{db} \\
- \code{triple} & \bond{triple} & \code{tp} \\
- \code{dotted} & \bond{dotted} & \code{semisingle} \\
- \code{deloc} & \bond{deloc} & \code{semidouble} \\
- \code{tdeloc} & \bond{tdeloc} & \code{semitriple} \\
- \code{co>} & \bond{co>} & \code{coordright} \\
- \code{<co} & \bond{<co} & \code{coordleft} \\
- \bottomrule
- \end{tabular}
-\end{table}
-
-\begin{beispiel}
- \ch{C\bond{sb}C\bond{db}C\bond{tp}C\bond{deloc}C\bond{tdeloc}C\bond{co>}C\bond{<co}C}
-\end{beispiel}
-
-\paragraph{Eigene Bindungen}
-\chemformula stellt Befehle bereit, mit denen eigene Bindungen definiert werden
-können:
-\begin{beschreibung}
- \Befehl{DeclareChemBond}{<name>}\ma{<code>}
- \Befehl{RenewChemBond}{<name>}\ma{<code>}
- \Befehl{DeclareChemBondAlias}{<new name>}\ma{<old name>}
- \Befehl{ShowChemBond}{<name>}
-\end{beschreibung}
-Die Verwendung wird am ehesten durch ein Beispiel beschrieben. Schauen Sie zunächst,
-wie die \code{single} und die \code{co>} Bindung definiert sind:
-\begin{beispiel}[code only]
- \DeclareChemBond{single}
- { \draw[chembond] (chemformula-bond-start) -- (chemformula-bond-end) ; }
- \DeclareChemBond{coordright}
- { \draw[chembond,butt cap->] (chemformula-bond-start) -- (chemformula-bond-end) ; }
- \DeclareChemBondAlias{co>}{coordright}
-\end{beispiel}
-Hier sind zwei Dinge wichtig: die Namen der Anfangs- und der Endkoordinaten,
-\code{chemformula-bond-start} und \code{chemformula-bond-end}, und der \TikZ-Stil
-der Bindungen \code{chembond}.
-
-Sagen wir, Sie wollen eine bestimmte Art von gestrichelter Bindung definieren.
-Sie könnten folgendes tun:
-\begin{beispiel}
- \usetikzlibrary{decorations.pathreplacing}
- \makeatletter
- \DeclareChemBond{dashed}
- {
- \draw[
- chembond,
- decorate,
- decoration={ticks,segment length=\chemformula@bondlength/10,amplitude=1.5pt}]
- (chemformula-bond-start) -- (chemformula-bond-end) ;
- }
- \makeatother
- \chemsetup[chemformula]{bond-length=2ex}
- \ch{C\bond{dashed}C}
-\end{beispiel}
-
-Dieses Beispiel zeigte Ihnen ein weiteres Makro: \makeatletter\cmd{chemformula@bondlength}\makeatother.
-Es existiert nur, damit Sie die Länge der Bindung, wie sie mit \key{bond-length}
-festgelegt wird, direkt verwenden können.% (siehe auch Seite~\pageref{key:bond-length}).
-
-\subsection{Anpassung}\secidx[Anpassung]{Summenformeln}\label{ssec:compounds:customization}
-Diese Optionen ermöglichen Ihnen, den Output anzupassen:
-\begin{beschreibung}
- \option{subscript-vshift}{<dim>} Extra vertikale Verschiebung der Tiefstellungen.
- Default = \code{0pt}
- \option{subscript-style}{text|math} Stil, der für die Tiefstellungen verwendet
- wird. Default = \code{text}
- \option{charge-hshift}{<dim>} Verschiebung von Hochstellungen, wenn sie einer
- Tiefstellung folgen. Default = \code{.25em}\label{desc:charge-hshift}
- \option{charge-style}{text|math} Stil, der für Hochstellungen verwendet wird.
- Default = \code{text}
- \option{adduct-space}{<dim>} Leerraum links und rechts des Addukt-Punktes.
- Default = \code{.1333em}
- \option{bond-length}{<dim>} Die Länge der Bindungen. Default = \code{.5833em}
- \option{bond-offset}{<dim>} Der Abstand zwischen Atom und Bindung. Default =
- \code{.07em}
- \option{bond-style}{<tikz>} \TikZ-Optionen für die Bindungen. Zunächst
- undefiniert.
- \option{radical-style}{<tikz>} \TikZ-Optionen für den Radikalpunkt. Zunächst
- undefiniert.
- \option{radical-radius}{<dim>} Der Radius des Radikalpunktes. Default =
- \code{.2ex}
- \option{radical-hshift}{<dim>} Horizontaler Leerraum vor dem Radikalpunkt.
- Default = \code{.15em}
- \option{radical-vshift}{<dim>} Vertikale Position des Radikalpunktes relativ zur
- aktuellen Grundlinie. Default = \code{.5ex}
- \option{radical-space}{<dim>} Horizontaler Leerraum nach dem Radikalpunkt.
- Default = \code{.15em}
-\end{beschreibung}
-
-Vielleicht ist Ihnen aufgefallen, dass bei manchen Ionen die Ladungen nach rechts
-verschoben sind:\secidx[Ladungen!Verschiebung]{Summenformeln}
-\begin{beispiel}
- \ch{SO4^2-} \ch{NH4+} \ch{Na+}
-\end{beispiel}
-Sie werden verschoben, wenn sie einer Tiefstellung \emph{folgen}, was der
-\ac{iupac}-Empfehlung entspricht \cite[][p.\,51]{iupac:greenbook}. Den Betrag der
-Verschiebung kann man mit der Option \key{charge-hshift} festlegen.
-\begin{beispiel}
- \ch{SO4^2-} \ch{NH4+} \ch{Na+} \\
- \chemsetup[chemformula]{charge-hshift=.5ex}
- \ch{SO4^2-} \ch{NH4+} \ch{Na+} \\
- \chemsetup[chemformula]{charge-hshift=.5pt}
- \ch{SO4^2-} \ch{NH4+} \ch{Na+}
-\end{beispiel}
-
-Ungeachtet der \ac{iupac}-Empfehlung erstellt \chemformula keine voll gestaffelten
-Hochstellungen in der Voreinstellung, da ich die in manchen Fällen schwer zu lesen
-und in anderen Fällen hässlich finde. Da das aber eine subjektive Empfindung ist,
-gibt Ihnen \chemformula nicht nur die Möglichkeit, einen absoluten Wert für die
-Verschiebung festzulegen, sondern stellt auch eine Möglichkeit für voll gestaffelte
-Hochstellungen bereit. Dafür verwenden Sie \key{charge-hshift}{full}.
-\begin{beispiel}
- \ch[charge-hshift=0pt]{C5H11+} \ch[charge-hshift=0pt]{SO4^2-} \\
- \ch{C5H11+} \ch{SO4^2-} \\
- \ch[charge-hshift=1ex]{C5H11+} \ch[charge-hshift=1ex]{SO4^2-} \\
- \ch[charge-hshift=full]{C5H11+} \ch[charge-hshift=full]{SO4^2-}
-\end{beispiel}
-
-Wenn Sie nicht wollen, dass die Ladungen im Textmodus gesetzt werden, können Sie
-zum Mathematikmodus schalten:
-\begin{beispiel}
- \ch{M^x+} \ch{SO4^2-} \\
- \chemsetup[chemformula]{charge-style = math}
- \ch{M^x+} \ch{SO4^2-}
-\end{beispiel}
-
-Die Option \key{subscript-vshift} kann verwendet werden, um die vertikale Verschiebung
-der Tiefstellungen anzupassen.\secidx[Tiefstellungen!Verschiebung]{Summenformeln}
-\begin{beispiel}
- \ch{H2SO4} \ch{Na3PO4} \\
- \chemsetup[chemformula]{subscript-vshift=.5ex}
- \ch{H2SO4} \ch{Na3PO4} \\
- \chemsetup[chemformula]{subscript-vshift=-.2ex}
- \ch{H2SO4} \ch{Na3PO4}
-\end{beispiel}
-
-Sie können außerdem wählen, in welchem Modus die Tiefstellungen gesetzt werden:
-\begin{beispiel}
- \ch{A_nB_m} \ch{H2SO4} \\
- \chemsetup[chemformula]{subscript-style = math}
- \ch{A_nB_m} \ch{H2SO4}
-\end{beispiel}
-
-Mit der Option \key{adduct-space} kann der Leerraum links und rechts des
-Addukt-Zeichens festgesetzt werden.
-\begin{beispiel}
- \ch{Na3PO3*H2O} \\
- \chemsetup[chemformula]{adduct-space=.2em}
- \ch{Na3PO3*H2O}
-\end{beispiel}
-
-Die Länge der Bindungen ändern:\secidx[Bindungen!Laenge@Länge]{Summenformeln}
-\begin{beispiel}
- \chemsetup[chemformula]{bond-length=4mm}%
- single: \ch{CH3-CH3} \\
- double: \ch{CH2=CH2} \\
- triple: \ch{CH+CH}
-\end{beispiel}
-
-Sie können ebenfalls den Abstand zwischen Atom und Bindung einstellen:
-\begin{beispiel}
- \ch{H-H + N+N + O=O} \\
- \ch[bond-offset=1pt]{H-H + N+N + O=O}
-\end{beispiel}

-\section{Spezielle Input-Typen}\secidx{Spezielle Input-Typen}
-Es gibt einige \enquote{spezielle Input-Typen}.
-
-\subsection{Single-Token Input}\secidx[Single-Token Input]{Spezielle Input-Typen}
-Die erste Sorte besteht nur aus einem Token, nämlich einem der folgenden:
-\begin{beschreibung}
- \befehl{ch}{ + } \ch{+} Erstellt ein Plus-Zeichen zwischen Formeln mit Leerraum
- links und rechts:\\
- \cmd{ch}{2 Na + Cl2} \ch{2 Na + Cl2}
- \befehl{ch}{ v } \ch{v} Zeichen für eine Fällung/Niederschlag: \cmd{ch}{BaSO4 v} \ch{BaSO4 v}
- \befehl{ch}{ \lstinline+^+ } \ch{^} Zeichen für entweichendes Gas: \cmd{ch}{\lstinline=H2 ^=} \ch{H2 ^}
-\end{beschreibung}
-
-Der Leerraum links und rechts des Plus kann mit einer Option angepasst werden:
-\begin{beschreibung}
- \option{plus-space}{<skip>} Eine elastische Länge. Default =
- \code{.3em plus .1em minus .1em}
-\end{beschreibung}
-\begin{beispiel}
- \ch{A + B}\\
- \ch[plus-space=4pt]{A + B}
-\end{beispiel}
-
-\subsection{Optionen Input}\secidx[Optionen Input]{Spezielle Input-Typen}
-Manchmal möchte man eine Option nur auf einen Teil einer, sagen wir, Reaktion
-anwenden. Natürlich können Sie \cmd{ch} mehrmals verwenden.
-\begin{beispiel}
- \ch{H2O +}\textcolor{red}{\ch{H2SO4}}\ch{-> H3O+ + HSO4-} \\
- \ch{H2O +}\ch[subscript-vshift=2pt]{H2SO4}\ch{-> H3O+ + HSO4-}
-\end{beispiel}
-Das unterbricht allerdings die Eingabe im Quelltext und \emph{könnte} die Abstände
-beeinflussen. Deshalb gibt es eine Alternative:
-\begin{beschreibung}\makeatletter
- \befehl{ch}{ @\{<options>\} } Die angegebenen Optionen sind \emph{nur} aktiv bis
- nach der \emph{nächsten} Summenformel.
-\end{beschreibung}
-\begin{beispiel}
- \ch{H2O +}\textcolor{red}{\ch{H2SO4}}\ch{-> H3O+ + HSO4-} \\
- \ch{H2O + @{format=\color{red}} H2SO4 -> H3O+ + HSO4-} \\
- oder nat\"urlich:\\
- \ch{H2O + \textcolor{red}{H2SO4} -> H3O+ + HSO4-}\\[1em]
- \ch{H2O +}\ch[subscript-vshift=2pt]{H2SO4}\ch{-> H3O+ + HSO4-} \\
- \ch{H2O + @{subscript-vshift=2pt} H2SO4 -> H3O+ + HSO4-}
-\end{beispiel}
-\achtung{Das ist ein experimentelles Feature und mag in zukünftigen Versionen
-fallen gelassen werden.}
-\secidx*{Spezielle Input-Typen}
-
-\section{Geschützter Input}\secidx{Geschützter Input}[Geschuetzter Input]
-In manchen Fällen kann es wünschenswert sein, \chemformula davon abzuhalten, den
-Input zu verarbeiten. Es gibt zwei Möglichkeiten, das zu tun.
-
-\subsection{Text}\label{ssec:text}\secidx[text]{Geschützter Input}[Geschuetzter Input]
-Wenn Sie etwas zwischen \lstinline+" "+ oder \lstinline+' '+ setzen, dann wird der
-Input als normaler Text behandelt, abgesehen davon, das Leerzeichen nicht erlaubt
-sind und mit \lstinline+~+ eingegeben werden müssen.
-\begin{beschreibung}
- \Befehl{ch}{ "<escaped text>" }
- \Befehl{ch}{ '<escaped text>' }
-\end{beschreibung}
-\begin{beispiel}
- \ch{"\ox{2,Ca}" O} \\
- \ch{"\ldots\," Na + "\ldots\," Cl2 -> "\ldots\," NaCl} \\
- \ch{'A~->~B'}
-\end{beispiel}
-In vielen Fällen wird das nicht nötig sein. Aber wenn Sie Schwierigkeiten haben,
-einen Befehl innerhalb von \cmd{ch} zu verwenden, versuchen Sie die geschützte
-Methode.
-
-\subsection{Mathematik}\secidx[math]{Geschützter Input}[Geschuetzter Input]
-Wenn Sie speziell Mathematik-Input haben, setzen Sie ihn einfach zwischen
-\lstinline+$ $+. Der Output unterscheidet sich vom geschützten Text (abgesehen
-von Mathe-Layout) darin, dass ihm ein Leerraum folgt. Der Grund dafür ist, dass
-ich davon ausgehe, das Mathe-Eingabe vor allem an Stelle von stöchiometrischen
-Faktoren eingesetzt wird.
-\begin{beschreibung}
- \Befehl{ch}{ \string$<escaped math>\string$ }
- \Befehl{ch}{ \string\(<escaped math>\string\) }
-\end{beschreibung}
-\begin{beispiel}
- escaped text: \ch{"$x$" H2O} \\
- escaped math: \ch{$x$ H2O} \\
- also escaped math: \ch{\(x\) H2O} \\
- \ch{$2n$ Na + $n$ Cl2 -> $2n$ NaCl}
-\end{beispiel}
-
-Der Leerraum, der nach dem geschützen Mathe-Input ausgegeben wird, kann angepasst
-werden.
-\begin{beschreibung}
- \option{math-space}{<skip>} Eine elastische Länge. Default =
- \code{.1667em plus .0333em minus .0117em}
-\end{beschreibung}
-\begin{beispiel}
- \ch{$2n$ Na + $n$ Cl2 -> $2n$ NaCl} \\
- \chemsetup[chemformula]{math-space=.25em}
- \ch{$2n$ Na + $n$ Cl2 -> $2n$ NaCl} \\
- \ch{$A->B$}

-\section{Pfeile}\label{sec:arrows}\secidx{Pfeile}
-\subsection{Pfeiltypen}\secidx[Typen]{Pfeile}
-Pfeile werden auf die gleiche intuitive Weise eingegeben wie bei \paket{mhchem}.
-Es gibt eine Reihe verschiedener Typen:
-\begin{beschreibung}
- \befehl{ch}{ -> } \ch{->} Standardpfeil nach rechts
- \befehl{ch}{ <- } \ch{<-} Standardpfeil nach links
- \befehl{ch}{ -/> } \ch{-/>} reagiert nicht (rechts)
- \befehl{ch}{ </- } \ch{</-} reagiert nicht (links)
- \befehl{ch}{ <-> } \ch{<->} Mesomerie-Pfeil
- \befehl{ch}{ <> } \ch{<>} Reaktion in beide Richtungen
- \befehl{ch}{ == } \ch{==} stöchiometrische Gleichung
- \befehl{ch}{ <=> } \ch{<=>} Gleichgewichts-Pfeil
- \befehl{ch}{ \lstinline+<=>>+ } \ch{<=>>} Gleichgewicht liegt rechts
- \befehl{ch}{ \lstinline+<<=>+ } \ch{<<=>} Gleichgewicht liegt links
- \befehl{ch}{ <o> } \ch{<o>} Isolobal-Pfeil
-\end{beschreibung}
-Diese Pfeile werden alle mit \TikZ gezeichnet.
-\begin{beispiel}
- \ch{H2 + Cl2 -> 2 HCl} \\
- \ch{H2O + CO3^2- <=> OH- + HCO3-} \\
- \ch{A <- B} \\
- \ch{\{[CH2=CH-CH2]- <-> [CH2-CH=CH2]- \}} \\
- \ch{A <> B} \\
- \ch{H+ + OH- <=>> H2O} \\
- \ch{2 NO2 <<=> N2O4}
-\end{beispiel}
-
-\subsection{Beschriftung}\secidx[Beschriftung]{Pfeile}
-Die Pfeile haben zwei optionale Argumente für Beschriftungen.
-\begin{beschreibung}
- \Befehl{ch}{ ->[<above>][<below>] }
-\end{beschreibung}
-\begin{beispiel}
- \ch{A ->[a] B} \\
- \ch{A ->[a][b] B} \\
- \ch{A ->[\SI{100}{\celsius}] B}
-\end{beispiel}
-Der Beschriftungstext kann unabhängig vom Pfeil verarbeitet werden. Das Rezept
-ist einfach: verwenden Sie Leerzeichen.
-\begin{beispiel}
- \ch{A ->[H2O] B} \\
- \ch{A ->[ H2O ] B} \\
- \ch{A ->[ "\ox{2,Ca}" F2 ] B} \\
- \ch{A ->[$\Delta$,~ \[H+ \]] B}
-\end{beispiel}
-
-Mit den Leerzeichen verarbeitet \chemformula den Teil zwischen den Klammern als
-normalen Input. Die Pfeile lesen ihre Argumente erst \emph{nach} der Verarbeitung.
-Wie Sie sehen können \enquote{wachsen} die Pfeile mit der Länge der Beschriftungen.
-Konstant bleibt der überstehende Teil. Im letzten Beispiel können Sie außerdem
-sehen, dass eckige Klammern in den Pfeilargumenten durch \cmd{[} und \cmd{]}
-erstellt werden sollten. Außerhalb von \cmd{ch} behalten Sie natürlich ihre
-übliche Bedeutung. Diese Befehle sind nötig da die sonst übliche Methode (Verstecken
-der Klammern in geschweiften Klammern) aufgrund der Art, wie \cmd{ch} sein Argument
-liest, nicht funktioniert.
-\begin{beispiel}
- \ch{A ->[a] B} \\
- \ch{A ->[ab] B} \\
- \ch{A ->[abc] B} \\
- \ch{A ->[abc~abc] B} \\
- % needs the `chemfig' package:
- \setatomsep{15pt}
- \ch{A ->[ "\chemfig{-[:30]-[:-30]OH}" ] B} \\
- \ch{A ->[[]] B} vs. \ch{A ->[\[\]] B}
-\end{beispiel}
-
-\subsection{Anpassung}\secidx[Anpassung]{Pfeile}
-Mit folgenden Optionen können Sie das Erscheinungsbild der Pfeile anpassen:
-\begin{beschreibung}
- \option{arrow-offset}{<dim>} Die Länge, die ein Pfeil links und rechts über die
- Beschriftung hinausragt. Die Länge eines leeren Pfeils beträgt zwei mal
- \code{arrow-offset}. Eine \TeX-Länge. Default = \code{.75em}
- \option{arrow-min-length}{<dim>} Die minimale Länge, die ein Pfeil hat, wenn
- zwei mal \key{arrow-offset} plus die Breite der Beschriftung nicht größer ist.
- Default = \code{0pt}
- \option{arrow-yshift}{<dim>} Verschiebt einen Pfeil nach oben (positiver Wert)
- oder nach unten (negativer Wert). Eine \TeX-Länge. Default = \code{0pt}
- \option{arrow-ratio}{<factor>} Das Verhältnis der Pfeillängen der ver unbalancierten
- Gleichgewichtspfeile. \code{.4} würde bedeuten, dass der kürzere Pfeil $0.4$
- mal so lang ist, wie der längere Pfeil. Default = \code{.6}
- \option{compound-sep}{<dim>} Der Leerraum zwischen Formeln und Pfeilen. Eine
- \TeX-Länge. Default = \code{.5em}
- \option{label-offset}{<dim>} Der Leerraum zwischen Pfeilen und ihrer Beschriftung.
- Eine \TeX-Länge. Default = \code{2pt}
- \option{label-style}{<font command>} Die relative Schriftgröße der Beschriftung.
- Default = \lstinline+\footnotesize+
-\end{beschreibung}
-
-Der folgende Code zeigt die Effekte der verschiedenen Optionen auf den
-\lstinline+<=>>+ Pfeil:
-\begin{beispiel}
- Standard: \ch{A <=>>[x][y] B} \\
- l\"anger: \ch[arrow-offset=12pt]{A <=>>[x][y] B} \\
- h\"oher: \ch[arrow-yshift=2pt]{A <=>>[x][y] B} \\
- ausbalancierter: \ch[arrow-ratio=.8]{A <=>>[x][y] B} \\
- Bschriftung weiter weg: \ch[label-offset=4pt]{A <=>>[x][y] B} \\
- gr\"o\ss erer Abstand zu Formeln: \ch[compound-sep=2ex]{A <=>>[x][y] B} \\
- kleinere Beschriftungen: \ch[label-style=\tiny]{A <=>[x][y] B}
-\end{beispiel}
-
-\subsection{Pfeiltypen bearbeiten}\label{sec:arrows_modify}\secidx[Typen!bearbeiten]{Pfeile}
-Die Pfeile wurden mit dem Befehl
-\begin{beschreibung}
- \Befehl{DeclareChemArrow}{<tokens>}\ma{<tikz>}
-\end{beschreibung}
-definiert. \ma{<tokens>} sind die Zeichen, die ersetzt werden mit dem tatsächlichen
-Pfeilcode. Der Hauptpfeil wurde \zB via
-\begin{beispiel}[code only]
- \DeclareChemArrow{->}{\draw[-cf] (cf_arrow_start) -- (cf_arrow_end) ;}
-\end{beispiel}
-definiert. Wenn Sie selbst Pfeile definieren wollen, benötigen Sie grundlegende
-Kenntnisse von \TikZ\footnote{Bitte lesen Sie dazu das \textsf{pgfmanual}.}.
-
-Es gibt einige vordefinierte Koordinaten, die Sie verwenden können und sollten:
-\begin{description}
- \item[\code{(cf\_arrow\_start)}] Der Pfeilanfang.
- \item[\code{(cf\_arrow\_end)}] Das Pfeilende.
- \item[\code{(cf\_arrow\_mid)}] Die Pfeilmitte.
- \item[\code{(cf\_arrow\_mid\_start)}] Der Anfang des kürzeren Pfeils in Typen
- wie \lstinline+<=>>+.
- \item[\code{(cf\_arrow\_mid\_end)}] Das Ende des kürzeren Pfeils in Typen wie
- \lstinline+<=>>+.
- \item[\code{cf}, \code{left cf}, \code{right cf}] Für \chemformula definierte
- Pfeilspitzen.
-\end{description}
-\begin{beispiel}
- \DeclareChemArrow{.>}{\draw[-cf,dotted,red] (cf_arrow_start) -- (cf_arrow_end);}
- \DeclareChemArrow{n>}{\draw[-cf] (cf_arrow_start) .. controls ([yshift=3ex]cf_arrow_mid) .. (cf_arrow_end);}
- \ch{A .> B} \ch{A .>[a][b] B} \ch{A n> B}
-\end{beispiel}
-Wenn Sie einen existierenden Pfeil umdefinieren möchten, können Sie folgende zwei
-Befehle verwenden:
-\begin{beschreibung}
- \Befehl{RenewChemArrow}{<tokens>}\ma{<tikz>}
- \Befehl{ShowChemArrow}{<tokens>}
-\end{beschreibung}
-Der zweite zeigt Ihnen die bestehende Definition, der erste definiert den bestehenden
-Pfeil neu.
-\begin{beispiel}
- \texttt{\ShowChemArrow{->}} \\
- \RenewChemArrow{->}{\draw[->,red] (cf_arrow_start) -- (cf_arrow_end) ;}
- \texttt{\ShowChemArrow{->}} \\

-\subsection{Syntax}\secidx[syntax]{Text unter Formeln}
-\chemformula hat eine eingebaute Syntax, um Text unter Formeln zu schreiben. Sie
-funktioniert ähnlich wie die optionalen Argumente der Pfeile.
-\begin{beschreibung}
- \Befehl{ch}{ !(<name>)( <formula> ) }
-\end{beschreibung}
-Wenn ein Ausrufezeichen von einem Paar von Klammern gefolgt wird, macht \chemformula folgendes:
-\begin{beispiel}
- \ch{!(ethanol)( CH2CH2OH )}
-\end{beispiel}
-
-Das gleiche, was für die Pfeilbeschriftungen gilt, gilt auch hier: wenn Sie Leerzeichen
-lassen, werden die verschiedenen Teile entsprechend ihres Typs verarbeitet, bevor
-der Text unter die Formel geschrieben wird.
-\begin{beispiel}
- \ch{!(water)(H2O)} \quad
- \ch{!( "\textcolor{blue}{water}" )( H2O )} \quad
- \ch{!( $2n-1$ )( H2O )} \quad
- \ch{!( H2O )( H2O )} \quad
- \ch{!(oxonium)( H3O+ )}
-\end{beispiel}
-
-Wenn Sie aus irgendeinem Grund ein Ausrufezeichen wollen, \emph{ohne} dass es
-einen Text unter eine Formel setzt, müssen Sie lediglich darauf achten, dass ihm
-keine Klammern folgen.
-\begin{beispiel}
- \ch{H2O~(!)} \\
- \ch{A!{}()}
-\end{beispiel}
-
-\subsection{Anpassung}\secidx[Anpassung]{Text unter Formeln}
-\chemformula stellt zwei Optionen bereit, um den Text anzupassen:
-\begin{beschreibung}
- \option{name-format}{<commands>} Das Ausgabeformat des Textes. Das kann beliebiger
- Input sein. Default = \lstinline+\scriptsize\centering+
- \option{name-width}{<dim>|auto} Die Breite der Box, in die der Text geschrieben wird.
- \code{auto} erkennt die Breite der Beschriftung und setzt die Box auf diese Breite.
- Default = \code{auto}
-\end{beschreibung}
-\begin{beispiel}
- \ch{!(S\"aure)( H2SO4 ) -> B} \\
- \ch[name-format=\sffamily\small]{!(S\"aure)( H2SO4 ) -> B} \\
- \ch[name-format=\scriptsize N:~]{!(S\"aure)( H2SO4 ) -> B} \\
- \ch[name-width=3em,name-format=\scriptsize\raggedright]{!(S\"aure)( H2SO4 ) -> B}
-\end{beispiel}

-\section{Format und Schrift}\label{sec:format}\secidx{Format und Schrift}
-Als Standardeinstellung nimmt \chemformula keine Veränderungen am Output der Formeln
-vor. Lassen Sie uns einen Nonsens-Input nehmen, der alle \chemformula-Features zeigt:
-\begin{beispiel}
- \newcommand*\sample{\ch{H2C-C+C-CH=CH+ + CrO4^2- <=>[x][y] 2.5 Cl^{-.} + 3_1/2 Na*OH_{(aq)} + !(name)( A^n ) "\LaTeXe"}}
- \sample
-\end{beispiel}
-\newcommand*\sample{\ch{H2C-C+C-CH=CH+ + CrO4^2- <=>[x][y] 2.5 Cl^{-.} + 3_1/2 Na*OH_{(aq)} + !(name)( A^n ) "\LaTeXe"}}
-Nun ändern wir verschiedene Aspekte der Schrift und sehen, was passiert:
-\begin{beispiel}[below]
- \sffamily Hallo \sample \\
- \ttfamily Hallo \sample \normalfont \\
- \bfseries Hallo \sample \normalfont \\
- \itshape Hallo \sample
-\end{beispiel}
-Wie Sie sehen, adaptieren die meisten Features die Einstellungen des umliegenden Fonts.
-
-Wenn Sie dieses Default-Verhalten oder das Default-Format ändern wollen, können
-Sie diese Option verwenden:
-\begin{beschreibung}
- \option{format}{<anything>} Fügt zu Beginn des \cmd{ch}-Befehls beliebigen Code
- ein.
-\end{beschreibung}
-\begin{beispiel}
- % blau und serifenlos:
- \definecolor{newblue}{rgb}{.1,.1,.5}\chemsetup[chemformula]{format=\color{newblue}\sffamily}
- \sffamily Hallo \sample \\
- \ttfamily Hallo \sample \normalfont \\
- \bfseries Hallo \sample \normalfont \\
- \itshape Hallo \sample
-\end{beispiel}
-
-Sie können ebenfalls speziell die Schriftfamilie, Schriftserie und Schriftform des
-Output setzen:
-\begin{beschreibung}
- \option{font-family}{<family>} Ändert die Schriftfamilie des Output mit:
- \lstinline+\fontfamily{<family>}\selectfont+.
- \option{font-series}{<series>} Ändert die Schriftserie des Output mit:
- \lstinline+\fontseries{<series>}\selectfont+.
- \option{font-shape}{<shape>} Ändert die Schriftform des Output mit:
- \lstinline+\fontshape{<shape>}\selectfont+.
-\end{beschreibung}
-\begin{beispiel}
- % immer fett:
- \chemsetup[chemformula]{font-series=bx}
- Hallo \sample \\
- \sffamily Hallo \sample \normalfont \\
- \chemsetup[chemformula]{font-family=lmr,font-series=m} Hallo \sample \normalfont \\
- \itshape Hallo \sample
-\end{beispiel}
-
-Wenn Sie \XeLaTeX\ oder \LuaLaTeX\ verwenden und das Paket \paket{fontspec} geladen
-haben, können Sie die Schrift von \chemformula auch damit ändern:
-\begin{beschreibung}
- \Option{font-spec}{\{<font>\}} oder mit Optionen
- \Option{font-spec}{\{[<options>]<font>\}}
-\end{beschreibung}
-\begin{beispiel}
- \chemsetup[chemformula]{font-spec={Linux Biolinum O}} \sample \\
- \chemsetup[chemformula]{font-spec={[Color=darkgray]Augie}} \sample \\
- \chemsetup[chemformula]{font-spec={Tipbrush Script}} \sample \\
- \chemsetup[chemformula]{font-spec={Latin Modern Sans}} \sample \\
- \bfseries \sample \normalfont \\
- \chemsetup[chemformula]{font-spec={Feathergraphy Decoration}} \sample

-\section{Verwendung in Mathematik-Umgebungen}\secidx{Mathematik-Umgebungen}
-Der Befehl \cmd{ch} kann in Mathematikumgebungen eingesetzt werden. Er erkennt
-\lstinline+\\+ und \lstinline+&+ und reicht sie weiter. Sie können aber die
-optionalen Argumente von \lstinline+\\+ nicht innerhalb von \cmd{ch} verwenden.
-\begin{beispiel}
- \begin{align}
- \ch{
- H2O & ->[a] H2SO4 \\
- Cl2 & ->[x][y] CH4
- }
- \end{align}
- \begin{align*}
- \ch{

-\section{Die Gefahren- (H) und Sicherheitssätze (P) aufrufen}\secidx{Gefahren- und Sicherheitssätze}[Gefahren- und Sicherheitssaetze]
-\subsection{Einfacher Aufruf}\secidx[Aufruf]{GHSYSTEM}
-Der prinzipielle Aufruf ist einfach:
-\begin{beschreibung}
- \Befehl{ghs}[<options>]{<type>}\ma{<number>}
- \Befehl[ghsa]{ghs*}[<options>]{<type>}\ma{<number>}
-\end{beschreibung}
-Es gibt drei Typen von Sätzen: \code{h}, \code{euh} und \code{p}. Das \ma{<type>}
-Argument ignoriert Groß- und Kleinschreibung.
-\begin{beispiel}
- \ghs{h}{200} \\
- \ghs{H}{224} \\
- \ghs{euh}{001} \\
- \ghs{Euh}{202} \\
- \ghs{p}{201}
-\end{beispiel}
-
-Die gesternte Version versteckt die Nummer und liefert nur den Satz. Wenn Sie den
-Satz verstecken und nur die Nummer ausgeben wollen, können Sie dises Option
-verwenden:
-\begin{beschreibung}
- \Option{hide}{\default{true}|false}
-\end{beschreibung}
-
-Außerdem gibt es eine Option, mit der der Output angepasst werden kann.
-\begin{beschreibung}
- \option{space}{<space command>} Leerraum zwischen \code{<type>} und \code{<number>}.
-\end{beschreibung}
-\begin{beispiel}

- \ghs[hide]{h}{200}
-\end{beispiel}
-
-\subsection{Sätze mit Platzhaltern}\secidx[Platzhalter]{GHSYSTEM}
-Einige Sätze verwenden Platzhalter. Es gibt vier Stück:
-\begin{itemize}
- \item \textit{\textless Expositionsweg angeben, sofern schlüssig belegt ist, dass
- diese Gefahr bei keinem anderen Expositionsweg besteht\textgreater}
- \item \textit{\textless konkrete Wirkung angeben, sofern bekannt\textgreater}
- \item \textit{\textless oder alle betroffenen Organe nennen, sofern bekannt\textgreater}
- \item \textit{\textless Name des sensibilisierenden Stoffes\textgreater}
-\end{itemize}
-
-Außer dem letzten, der ersetzt werden muss, sind sie in der Voreinstellung versteckt.
-Durch die Option
-\begin{beschreibung}
- \option{fill-in}{\default{true}|false} Default = \code{false}
-\end{beschreibung}
-können sie sichtbar gemacht werden.
-\begin{beispiel}[below]
- \ghs{h}{340} \\
- \ghs[fill-in]{h}{340} \\
- \ghs{h}{360} \\
- \ghs[fill-in]{h}{360} \\
- \ghs{h}{370} \\
- \ghs[fill-in]{h}{370} \\
- \ghs{euh}{208} \\
- \ghs[fill-in]{euh}{208}
-\end{beispiel}
-
-Mit folgenden Optionen können die Platzhalter ersetzt werden:
-\begin{beschreibung}
- \option{exposure}{<text>} Expositions-Platzhalter
- \option{effect}{<text>} Effekt-Platzhalter
- \option{organs}{<text>} Organ-Platzhalter
- \option{substance}{<text>} Substanz-Platzhalter
-\end{beschreibung}
-\begin{beispiel}
- \ghs[exposure=So werden Sie der Gefahr ausgesetzt.]{h}{340} \\
- \ghs[effect=Das sind die Effekte]{h}{360} \\
- \ghs[organs=dieses Organ]{h}{370} \\
- \ghs[substance=Substanz]{euh}{208}
-\end{beispiel}

-\subsection{Sätze mit Lücken}\secidx[Saetze mit Luecken@Sätze mit Lücken]{GHSYSTEM}
-Manche Sätze haben Lücken:
-\begin{beispiel}
- \ghs{p}{301} \\
- \ghs{p}{401} \\
- \ghs{p}{411} \\
- \ghs{p}{413}
-\end{beispiel}
-
-Mit den folgenden Optionen können diese Lücken gefüllt werden:
-\begin{beschreibung}
- \option{text}{<text>} Füllt \enquote{unsichtbare Lücke}, die einem Doppelpunkt
- folgt.
- \option{dots}{<text>} Füllt Lücke, die durch \enquote{\ldots} angezeigt wird.

-\section{Piktogramme}\secidx{Piktogramme}
-\subsection{Die Bilder}
-Das GHS beinhaltet einige Piktogramme:
-
-\ghspic{explos} \ghspic{flame} \ghspic{flame-O} \ghspic{bottle} \ghspic{acid}
-\ghspic{skull} \ghspic{exclam} \ghspic{health} \ghspic{aqpol}
-
-Der Befehl
-\begin{beschreibung}
- \Befehl{ghspic}[<options>]{<name>}
-\end{beschreibung}
-lädt sie. Tabelle~\ref{tab:ghs_pictograms} zeigt alle Piktogramme und ihre Dateinamen.
-Genauer: sie zeigt die Namen, die beim Befehl \cmd{ghspic} verwendet werden müssen.
-Tatsächlich heißen sie \lstinline=ghsystem_<name>.<filetype>=, wobei \code{<filetype>}
-entweder \code{eps}, \code{pdf}, \code{jpg} oder \code{png} ist, siehe auch
-Abschnitt~\ref{ssec:picture_type}.
-\begin{beispiel}
- \ghspic{skull}
-\end{beispiel}
-
-Wenn Ihnen die Defaultgröße nicht gefällt, können Sie die Option
-\begin{beschreibung}
- \option{scale}{<factor>} Skaliert das Piktogramm. Default = \code{1}
-\end{beschreibung}
-verwenden. Tatsächlich sind die Bilder recht groß. Die Voreinstellung (Faktor =
-$1$) skaliert die Bilder auf ein Zwanzigstel ihrer echten Größe.
-\begin{beispiel}
- \ghspic[scale=2]{skull}
-\end{beispiel}
-
-Wenn Sie spezielle \lstinline=\includegraphics=-Optionen verwenden wollen, \zB
-das Piktogramm rotieren, verwenden Sie diese Option:

-\subsection{Der Bildtyp hängt von der Engine ab}\label{ssec:picture_type}
-Sie wissen vermutlich, dass Sie nicht jeden Bildtyp mit jeder Compiler-Engine
-verwenden können. \pdfTeX{} im \acs{dvi}-Modus verlangt \code{eps}-Dateien,
-während \pdfTeX{} im \acs{pdf}-Modus, \XeTeX{} und \LuaTeX{} \code{eps}-Dateien
-in \code{pdf}-Dateien konvertieren, vorausgesetzt, der Anwender hat Schreibrechte
-in dem Verzeichnis, in dem die Bilder gespeichert sind.
-
-Die letztgenannten können jedoch \code{jpg}- und \code{png}-Dateien ohne Schwierigkeiten
-einbinden, während \pdfTeX{} im \acs{dvi}-Modus das nicht kann.
-
-Um das Problem zu lösen, testet \ghsystem, welche Engine verwendet wird und falls
-es \pdfTeX{} ist, in welchem Modus es verwendet wird. Dann wird entwder das
-\code{eps}- oder das \code{png}-Bild für die Piktogramme verwendet. Sie können
-den Bildtyp über die Option
-\begin{beschreibung}
- \Option{pic-type}{eps|pdf|jpg|png}
-\end{beschreibung}
-jedoch frei wählen.

-\section{Verfügbare Sprachen}\label{sec:ghsystem_language}
-Bis jetzt sind die H- und P-Sätze nur auf deutsch, englisch und italienisch verfügbar.
-Das Paket reagiert auf die \chemmacros Option \key[option]{german}, erkennt aber
-die Spracheinstellung von \paket{babel} oder \paket{polyglossia} (noch) nicht.
-
-Sie können die Sprache auch explizit wählen.
-\begin{beschreibung}

- \ghs{h}{201}
-
- \chemsetup[ghsystem]{language=english}
- \ghs{h}{201}

-
-Ich werde in irgendwann in der Zukunft weitere Sprachen implementieren. Das kann
-aber eine Weile dauern. Wenn Sie gerne zu \ghsystem beisteuern möchten und die
-Sätze in einer anderen Sprache tippen wollen, kontaktieren Sie mich\footnote{%
-\href{mailto:contact@mychemistry.eu}{contact@mychemistry.eu}} gerne. Ich stelle

+\section{Licence, Requirements and \textsc{README}}
+Permission is granted to copy, distribute and/or modify this software under
+the terms of the \LaTeX\ project public license (lppl) version 1.3 or later
+(\url{http://www.latex-project.org/lppl.txt}). The package has the status
+``maintained.''
-You might remember that \chemmacros' options all belong to different modules, see
-section~\ref{sec:setup} for further information. These are typeset in the left
-margin when the option is first mentioned. In section~\ref{sec:overview} all options
-and the module they belong to are listed. Throughout the document options are
-typeset \textcolor{key}{\code{green}} and modules \textcolor{module}{\code{red}}.
+The \chemmacros\ bundle needs the bundles \paket{l3kernel} and
+\paket{l3packages}. It also needs the packages \paket{siunitx},
+\paket{mathtools}, \paket{bm}, \paket{nicefrac} and \paket{environ} as well as
+\paket*{tikz}\footnote{\CTANurl[graphics]{pgf}} and the \TikZ libraries
+\code{calc} and \code{arrows}. Language support is done with the help of the
+\paket*{translations} package from the \paket{exsheets} bundle. The
+\chemmacros\ package also loads the other packages of this bundle.
-The package \ghsystem needs the packages \chemmacros, \paket{tabu}, \paket{longtable},
-\paket{ifpdf} and \paket{graphicx}. \ghsystem has no own package options but
-passes all options on to \chemmacros.
+The package option \key{xspace} also loads the package \paket{xspace}.
-\achtung{There are some deprecated commands and options which are not explained
-in the manual any more but still exist to ensure backwards compatibility. These
-commands issue a warning. They may be dropped some time in the future.}
+The \chemmacros\ bundle bundles four packages: \chemmacros, \chemformula,
+\ghsystem\ and \chemgreek. The package dependencies of the other packages are
+described in the respective manuals.
\section{Motivation and Background}
-\chemmacros started some years ago as a growing list of custom macros that I
-frequently used. I cannot completely recall when and why I decided to release them
-as a package. Well \textendash\ here we go and you might find it useful, too, I
-hope.
+\chemmacros\ started some years ago as a growing list of custom macros that I
+frequently used. I cannot completely recall when and why I decided to release
+them as a package. Well \textendash\ here we go and you might find it useful,
+too, I hope.
Both the macros and their functionality have changed over time and quite a lot
-have been added. Many things have been unified and what's probably most important:
-many possibilities to customize have been added, too.
-
-Probably every chemist using \LaTeXe\ is aware of the great \paket{mhchem} package
-by Martin Hensel. There have always been some difficulties intertwining it with
-\chemmacros, though. Also, some other minor points in \paket{mhchem} always
-bothered me, but they hardly seemed enough for a new package. They weren't even
-enough for a feature request to the \paket{mhchem} author. The challenge and the
-fun of creating a new package and the wish for a highly customizable alternative
-led to \chemformula after all.
-
-\chemformula works very similar to \paket{mhchem} but is more strict as to how
-compounds, stoichiometric factors and arrows are input. In the same time
-\chemformula offers possibilities to customize the output that \paket{mhchem} does
-not. Since \chemformula is meant as an \emph{alternative} to \paket{mhchem}
-\chemmacros offers a package option allowing you to choose which one of the two
-is used. The default however is \chemmacros own way: \chemformula.
-
-As a chemist you are probably aware of the fact that the \acl{UN} have developed
-the \ac{ghs} as a global replacement for the various different systems in different
-countries. While it has not been implemented by all countries
-yet~\cite{unece:ghsystem_implementation}, it is only a matter of time.
-
-The package \ghsystem now enables you to typeset all the hazard and precautionary
-statements and pictograms in a very easy way. The statements are taken from \acs{eu}
-regulation 1272/2008~\cite{eu:ghsystem_regulation}.

+\chemformula\ works very similar to \paket{mhchem} but is more strict as to

+\chemformula\ offers possibilities to customize the output that \paket{mhchem}
+does not. Although \chemformula\ is meant as an \emph{alternative} to
+\paket{mhchem} \chemmacros\ only loads \chemformula\ and uses it at various
+places internally, too.

There are four points I hope I have achieved with this bundle:
\begin{itemize}
\item intuitive usage as far as the syntax of the commands is concerned
- \item the commands shall not only make typesetting easier and faster but also the
- document source more readable with respect to semantics
+ \item the commands shall not only make typesetting easier and faster but also
+ the document source more readable with respect to semantics
(\code{\cmd{ortho}-dichlorobenzene} is easier to read and understand than
\code{\cmd*{textsl}{o}-dichlorobenzene})
\item as much customizability as I could think of so every user can adapt the
commands to his or her own wishes
\item default settings compliant with the recommendations of the \acf{iupac}.
\end{itemize}
-Especially the last point needed some pushing from users to get things right in
-many places. If you find anything not compliant with \ac{iupac} recommendations%
-\footnote{This does not concern the \cmd{ox} command. The \ac{iupac} version is
-\cmd{ox}*.} I would welcome an email very much!
-
-In a package this large with older parts and rather new parts (which have to be
-considered being in beta state) it is unavoidable that there are flaws and bugs.
-I am very keen on correcting and improving this package, so please: if you find
-anything that bothers you and may it be just so small please send me a short email
-and I'll see what I can do. I would especially like feedback on \chemformula (see
-part~\ref{part:chemformula}) and \ghsystem (see part~\ref{part:ghsystem}) but also
-welcome feedback on every other part of this bundle.

-\section{Installation, Loading the Bundle}\secidx{Loading the Bundle}\secidx{Installation}
-The bundle comes with three style files\footnote{Those ending \code{sty}.}, a
-directory called \code{language/} containing the language-definition files for
-\ac{ghs} (ending \code{def}), and a directory \code{pictures/} containing \code{eps},
-\code{pdf}, \code{jpg} and \code{png} files (the \ac{ghs} pictograms). If you install
-the bundle manually \emph{please make sure to place the directories \code{language/}
-and \code{pictures/} in the \emph{same} directory as the style files}.
-
-Loading \chemmacros with
-\begin{beispiel}[code only]
- \usepackage{chemmacros} % `chemmacros', `chemformula' and `ghsystem' are loaded
-\end{beispiel}
-will also load \chemformula and \ghsystem. However, you can prevent \chemmacros
-from loading \ghsystem:

- \usepackage[ghsystem=false]{chemmacros} % `chemmacros' and `chemformula' are loaded
-\end{beispiel}

+recommendations\footnote{This does not concern the \cmd{ox} command. The
+ \ac{iupac} version is \cmd{ox}*.} I would welcome an email very much!
-Loading \chemformula or \ghsystem explicitly is possible and will also load
-\chemmacros if it hasn't been loaded yet, and will therefore implicitly load the
-other package, too.
-\begin{beispiel}[code only]
- \usepackage{chemformula}
- or
- \usepackage{ghsystem}
-\end{beispiel}

-However, it is recommended to simply use \lstinline=\usepackage{chemmacros}= and
-setup the required options with \lstinline=\chemsetup= (also see section~\ref{sec:setup}).

+\section{News}\secidx{News}
+With version~4.0 some changes have been made:
+\begin{itemize}
+ \item first of all the packages \chemformula\ and \ghsystem\ do not load
+ \chemmacros\ any more which means they can be used independently.
+ \item the option \key{bpchem} has been dropped.
+ \item the commands \cmd{mch} and \cmd{pch} now match \chemformula's
+ charges.
+ \item the option \key{method} has been dropped.
+ \item the option \key[charges]{append} has deprecated.
+ \item the option \key{greek} has been extended to support other uppercase
+ greek letters, for example those provided by \paket{kpfonts}. This is
+ handled internally by the new package in the family: \chemgreek. This
+ package is not really a package for usage at a user-level but could in
+ principle be used to extend the \key{greek} option.
+ \item language support is now done with the help of the
+ \paket*{translations} package from the \paket{exsheets} bundle. This
+ means that with version~4.0 the document language is recognized
+ automatically.
+ \item the status of the commands \cmd{Lfi} and \cmd{Dfi} has been changed
+ from \emph{deprecated} to \emph{dropped}.
+ \item various other changes like bug fixes and improvements on the
+ typographical appearance of \chemformula's inline formulae with \cmd{ch}.

-\section{Setup}
-All of \chemformula's options belong to the module \textcolor{module}{\code{chemformula}}.
-This means they can be setup with
-\begin{beispiel}[code only]
- \chemsetup[chemformula]{<options>} or
- \chemsetup{chemformula/<option1>,chemformula/<option2>}
-\end{beispiel}
-
-\section{The Basic Principle}
-\chemformula offers one main command.
-\begin{beschreibung}
- \Befehl{ch}[<options>]{<input>}
-\end{beschreibung}
-The usage will seem very familiar to you if you're familiar with \paket{mhchem}:
-\begin{beispiel}
- \ch{H2O} \\
- \ch{Sb2O3} \\
- \ch{H+} \\
- \ch{CrO4^2-} \\
- \ch{AgCl2-} \\
- \ch{[AgCl2]-} \\
- \ch{Y^{99}+} \\
- \ch{Y^{99+}} \\
- \ch{H2_{(aq)}} \\
- \ch{NO3-} \\
- \ch{(NH4)2S} \\
- \ch{^{227}_{90}Th+} \\
- $V_{\ch{H2O}}$ \\
- \ch{Ce^{IV}} \\
- \ch{KCr(SO4)2 * 12 H2O}
-\end{beispiel}
-
-However, there are differences. The most notable one: \chemformula distinguishes
-between different types of input. These different parts \emph{have} to be separated
-with blanks:
-\begin{beschreibung}
- \Befehl{ch}{part1 part2 part3 part4}
-\end{beschreibung}
-A blank in the input \emph{never} is a blank in the output. This role of the blank
-strictly holds and disregarding it can have unexpected results and even lead to errors.
-
-Another notable difference: \chemformula tries to avoid math mode whenever possible:
-\begin{beispiel}
- \ch{A + B ->[a] C} \\
- \ce{A + B ->[a] C}
-\end{beispiel}
-
-This means that \cmd{ch}{2H2O} is recognized as a \emph{single} part, which in
-this case is recognized as a compound.
-\begin{beispiel}
- \ch{2H2O} \\
- \ch{2 H2O}
-\end{beispiel}
-This also means, that a part cannot contain a blank since this will automatically
-divide it into two parts. If you need an extra blank in the output you need to use
-\lstinline+~+. However, since commands in most cases gobble a space after them a
-input like \cmd{ch}{\textbackslash command ABC} will be treated as a single part.
-If you want or need to divide them you need to add an empty group:
-\cmd{ch}{\textbackslash command\{\} ABC}. The different input types are described
-in the following sections.
-
-There are some options to customize the output of the \cmd{ch} command. They can
-either be applied locally using the optional argument or can be set globally using
-the setup command. All options of \chemformula belong to the module
-\textcolor{module}{\code{chemformula}}.
-\begin{beschreibung}
- \Befehl{chemsetup}[chemformula]{<options>}

-\section{Stoichiometric Factors}\secidx{Stoichiometric Factors}
-A stoichiometric factor may only contain of numbers and the signs \lstinline+.,_/()+
-\begin{beispiel}
- \ch{2} \\
- \ch{12}
-
- % decimals:
- \ch{.5} \\
- \ch{5,75}
-
- % fractions:
- \ch{3/2} \\
- \ch{1_1/2}
-
- % ``iupac'':
- \ch{(1/2)}
-\end{beispiel}
-
-As you can see if you input decimal numbers a missing leading zero is added.
+\part{Other Packages of the Bundle}
-You have to be a little bit careful with the right syntax but I believe it is
-rather intuitive.
-\begin{beispiel}[code only]
- this won't work but will result in an error: \ch{1/1_1}
-\end{beispiel}
-
-If stoichiometric factors are enclosed with parentheses the fractions are not
-recognized and missing leading zeros are not added. What's inside the parentheses
-is typeset as is.
-\begin{beispiel}
- \ch{(1/2) H2O} \ch{1/2 H2O} \ch{0.5 H2O}
-\end{beispiel}
-You can find many examples like the following for stoichiometric factors in
-parentheses in the \acs{iupac} Green Book~\cite{iupac:greenbook}:
-\begin{reaction*}
- (1/5) K "\ox*{7,Mn}" O4 + (8/5) HCl == (1/5) "\ox*{2,Mn}" Cl2 + (1/2) Cl2 + (1/5) KCl + (4/5) H2O
-\end{reaction*}
-
-There are a few possibilities to customize the output.
-\begin{beschreibung}
- \option{decimal-marker}{<marker>} the symbol to indicate the decimal. Default =
- \code{.}
- \option{frac-style}{math|xfrac|nicefrac} determines how fractions are displayed.
- Default = \code{math}
- \option{stoich-space}{<skip>} The space that is placed after the stoichiometric
- factor. A rubber length. Default = \code{.1667em plus .0333em minus .0117em}
- \option{stoich-paren-parse}{\default{true}|false} If set to true stoichiometric
- factors enclosed by parentheses also are parsed. Default = \code{false}
-\end{beschreibung}
-\begin{beispiel}
- \ch[decimal-marker={,}]{3.5} \ch[decimal-marker={$\cdot$}]{3,5}
-\end{beispiel}
-
-The option \key{frac-style}{xfrac} uses the \lstinline+\sfrac+ command of the
-\paket{xfrac} package. The output strongly depends on the font you use.\secidx[xfrac]{Stoichiometric Factors}
-\begin{beispiel}
- \ch[frac-style=xfrac]{3/2} \ch[frac-style=xfrac]{1_1/2}
-\end{beispiel}
-\chemformula defines the instance \lstinline=formula-text-frac= which you can
-redefine to your needs. See the \paket{xfrac} documentation for further information.
-The default definition is this:
-\begin{beispiel}[code only]
- \DeclareInstance{xfrac}{chemformula-text-frac}{text}
- {
- slash-left-kern = -.15em ,
- slash-right-kern = -.15em
- }
-\end{beispiel}
-This document uses the font Linux Libertine~O and the following definition:
-\begin{beispiel}[code only]
- \DeclareInstance{xfrac}{chemformula-text-frac}{text}
- {
- scale-factor = 1 ,
- denominator-bot-sep = -.2ex ,
- denominator-format = \scriptsize #1 ,
- numerator-top-sep = -.2ex ,
- numerator-format = \scriptsize #1 ,
- slash-right-kern = .05em ,
- slash-left-kern = .05em
- }
-\end{beispiel}
-
-The option \key{frac-style}{nicefrac} uses the \lstinline+\nicefrac+ command of
-the \paket{nicefrac} package.\secidx[nicefrac]{Stoichiometric Factors}
-\begin{beispiel}
- \ch[frac-style=nicefrac]{3/2} \ch[frac-style=nicefrac]{1_1/2}
-\end{beispiel}
-
-The option \key{stoich-space} allows you to customize the space between
-stoichiometric factor and the group following after it.\secidx[space]{Stoichiometric Factors}
-\begin{beispiel}
- \ch{2 H2O} \\
- \ch[stoich-space=.3em]{2 H2O}
-\end{beispiel}
-\secidx*{Stoichiometric Factors}
-
-\section{Compounds}\label{ssec:compounds}\secidx{Compounds}
-\chemformula determines compounds as the type that ``doesn't fit in anywhere else.''
-This point will become more clear when you know what the other types are.
-\begin{beispiel}
- \ch{H2SO4} \\
- \ch{[Cu(NH3)4]^2+}
-\end{beispiel}
-
-\subsection{Adducts}\secidx[adducts]{Compounds}
-\chemformula has two identifiers which will create adducts.
-\begin{beschreibung}
- \befehl{ch}{A.B}
- \befehl{ch}{A*B}
-\end{beschreibung}
-\begin{beispiel}
- \ch{CaSO4.H2O} \\
- \ch{CaSO4*H2O}
-\end{beispiel}
-Since numbers in a compound always are treated as subscripts (see
-section~\ref{ssec:subscripts}) you sometimes need to introduce stoichiometric
-factors for the right output:
-\begin{beispiel}
- \ch{Na3PO4*12H2O} \\
- \ch{Na3PO4* 12 H2O} \\
- \ch{Na3PO4 * 12 H2O}
-\end{beispiel}
-
-\subsection{Subscripts}\label{ssec:subscripts}\secidx[subscripts]{Compounds}
-\emph{All} numbers in a compound are treated as subscripts.
-\begin{beispiel}
- \ch{H2SO4}
-\end{beispiel}
-If you want a letter to be a subscript you can use the math syntax:
-\begin{beispiel}
- \ch{A_nB_m}
-\end{beispiel}
-The subscript recognizes groups. You can also use math inside it.
-\begin{beispiel}
- \ch{A_{$n$}B_{$m$}} \\
- \ch{NaCl_{(aq)}}
-\end{beispiel}
-
-\subsection{Commands}\secidx[commands]{Compounds}
-Commands are allowed in a compound:
-\begin{beispiel}
- \ch{\textbf{A2}B3} \ch{A2\color{red}B3}
-\end{beispiel}
-However, if the commands demand numbers as argument, \eg space commands or
-\chemmacros' \lstinline+\ox+ command the direct use will fail. This is because
-the numbers are treated as subscripts \emph{before} the command expands.
-\begin{beispiel}[code only]
- \ch{A\hspace{2mm}B} will raise an error because \hspace sees something like
- this: \hspace{$_2$mm}. Actually not at all like it but equally bad\ldots
-\end{beispiel}
-See section~\ref{ssec:text} for a way around this.
-
-\subsection{Charges and Other Superscripts}\secidx[charges]{Compounds}\secidx[superscripts]{Compounds}
-\paragraph{Basics}
-If a compound \emph{ends} with a plus or minus sign it will be treated as charge
-sign and typeset as superscript. In other places a plus is treated as a triple
-bond and a dash will be used as a single bond, see section~\ref{ssec:bonds}.
-\begin{beispiel}
- \ch{A+B} \ch{AB+} \\
- \ch{A-B} \ch{AB-}
-\end{beispiel}
-
-For longer charge groups or other superscripts you can use the math syntax. It
-recognizes groups and you can use math inside them. Inside these groups neither
-\code{+} nor \code{-} are treated as bonds. If a dot \code{.} is inside a
-superscript it is treated as indicator for a radical. A \code{*} gives the
-excited state.
-\begin{beispiel}
- \ch{A^{x-}} \\
- \ch{A^x-} \\
- \ch{A^{x}-} \\
- \ch{A^{$x-$}} \\
- \ch{RNO2^{-.}} \\
- \ch{^31H} \\
- \ch{^{14}6C} \\
- \ch{^{58}_{26}Fe} \\
- \ch{NO^*}
-\end{beispiel}
-
-Ions and ion composites with more than one charge can be typeset quite as easy:
-\begin{beispiel}
- \ch{SO4^2-} \ch{Ca^2+ SO4^2-}
-\end{beispiel}
-
-\paragraph{Charge Commands}\secidx[superscripts!charge commands]{Compounds}
-You don't need to use \cmd{mch} and related commands inside \cmd{ch}. Indeed,
-you \emph{shouldn't} use them as they might mess with the subscript and superscript
-alignment. The \chemmacros option \code{circled} is obeyed by \cmd{ch}.
-\begin{beispiel}
- \chemsetup[option]{circled=all}
- \ch{H+ + OH- <=> H2O}
-\end{beispiel}
-
-\paragraph{Behaviour}\secidx[superscripts!behaviour]{Compounds}
-The supercripts behave differently depending on their position in a compound, if
-there are super- and subscripts following each other directly.
-\begin{beispiel}
- \ch{^33B} \ch{{}^33B} \ch{3^3B} \ch{B^3} \ch{B3^3} \\
- \ch{^{23}_{123}B} \ch{{}^{23}_{123}B} \ch{_{123}^{23}B} \ch{B^{23}} \ch{B_{123}^{23}} \\
- \ch{^{123}_{23}B} \ch{{}^{123}_{23}B} \ch{_{23}^{123}B} \ch{B^{123}} \ch{B23^{123}}
-\end{beispiel}
+The other three package, \chemformula, \ghsystem\ and \chemgreek, all have
+their own documentation:
\begin{itemize}
- \item If a compound \emph{starts} with a sub- or superscript both sub- and
- superscript are aligned to the \emph{right} else to the \emph{left}.
- \item If a compound \emph{does not start} with a sub- or superscript and there
- is both a sub- and a superscript, the superscript is shifted additionally by a
- length determined from the option \key{charge-hshift}{<dim>}, also see
- page~\pageref{desc:charge-hshift}f.
+ \item \url{chemformula_en.pdf}
+ \item \url{ghsystem_en.pdf}
+ \item \url{chemgreek_en.pdf}
\end{itemize}
-The second point follows \ac{iupac}'s recommendations:
-\begin{zitat}[{\acs{iupac} Green Book {\cite[][p.\,51]{iupac:greenbook}}}]
- In writing the formula for a complex ion, spacing for charge number can be added
- (staggered arrangement), as well as parentheses: \ch[charge-hshift=full]{SO4^2-},
- \ch{(SO4)^2-} The staggered arrangement is now recommended.
-\end{zitat}
-\subsection{Bonds}\label{ssec:bonds}\secidx[bonds]{Compounds}
-\subsubsection{Native Bonds}
-There are three kinds of what I will call ``native bonds'':
-\begin{beispiel}
- single: \ch{CH3-CH3} \\
- double: \ch{CH2=CH2} \\
- triple: \ch{CH+CH}
-\end{beispiel}
-
-\subsubsection{Flexible Bonds}
-\paragraph{Predefined Bonds}
-In addition to the three native bonds there are a few more which can be called by
-\begin{beschreibung}
- \Befehl{bond}{<bond name>}
-\end{beschreibung}
-The predefined bond types are shown in table~\ref{tab:bond_types}.
-
-\begin{table}
- \centering
- \caption{Bonds available with \protect\cmd{bond}.}
- \label{tab:bond_types}
- \begin{tabular}{lcl}
- \toprule
- \bfseries name & \bfseries appearance & \bfseries aliases \\
- \midrule
- \code{single} & \bond{single} & \code{normal}, \code{sb} \\
- \code{double} & \bond{double} & \code{db} \\
- \code{triple} & \bond{triple} & \code{tp} \\
- \code{dotted} & \bond{dotted} & \code{semisingle} \\
- \code{deloc} & \bond{deloc} & \code{semidouble} \\
- \code{tdeloc} & \bond{tdeloc} & \code{semitriple} \\
- \code{co>} & \bond{co>} & \code{coordright} \\
- \code{<co} & \bond{<co} & \code{coordleft} \\
- \bottomrule
- \end{tabular}
-\end{table}
-
-\begin{beispiel}
- \ch{C\bond{sb}C\bond{db}C\bond{tp}C\bond{deloc}C\bond{tdeloc}C\bond{co>}C\bond{<co}C}
-\end{beispiel}
-
-\paragraph{Own Bonds}
-\chemformula offers commands to define own bond types:
-\begin{beschreibung}
- \Befehl{DeclareChemBond}{<name>}\ma{<code>}
- \Befehl{RenewChemBond}{<name>}\ma{<code>}
- \Befehl{DeclareChemBondAlias}{<new name>}\ma{<old name>}
- \Befehl{ShowChemBond}{<name>}
-\end{beschreibung}
-The usage is best described with an example. So let's see how the \code{single}
-bond and the \code{co>} bond are defined:
-\begin{beispiel}[code only]
- \DeclareChemBond{single}
- { \draw[chembond] (chemformula-bond-start) -- (chemformula-bond-end) ; }
- \DeclareChemBond{coordright}
- { \draw[chembond,butt cap->] (chemformula-bond-start) -- (chemformula-bond-end) ; }
- \DeclareChemBondAlias{co>}{coordright}
-\end{beispiel}
-Two points are important: the names of the starting and the ending coordinates,
-\code{chemformula-bond-start} and \code{chemformula-bond-end}, and the \TikZ
-style of the bonds \code{chembond}.
-
-So, let's say you want to define a special kind of dashed bond. You could do this:
-\begin{beispiel}
- \usetikzlibrary{decorations.pathreplacing}
- \makeatletter
- \DeclareChemBond{dashed}
- {
- \draw[
- chembond,
- decorate,
- decoration={ticks,segment length=\chemformula@bondlength/10,amplitude=1.5pt}]
- (chemformula-bond-start) -- (chemformula-bond-end) ;
- }
- \makeatother
- \chemsetup[chemformula]{bond-length=2ex}
- \ch{C\bond{dashed}C}
-\end{beispiel}
-
-The last example showed you another macro: \makeatletter\cmd{chemformula@bondlength}\makeatother.
-It only exists so you can use it to access the bond length as set with \key{bond-length}
-directly.% (see also page~\pageref{key:bond-length}).
-
-\subsection{Customization}\secidx[customization]{Compounds}\label{ssec:compounds:customization}
-These options allow you to customize the ouptut of the compounds:
-\begin{beschreibung}
- \option{subscript-vshift}{<dim>} Extra vertical shift of the subscripts. Default
- = \code{0pt}
- \option{subscript-style}{text|math} Style that is used to typeset the subscripts.
- Default = \code{text}
- \option{charge-hshift}{<dim>} Shift of superscripts when following a subscript.
- Default = \code{.25em}\label{desc:charge-hshift}
- \option{charge-vshift}{<dim>} Extra vertical shift of the superscripts.
- Default = \code{0pt}
- \option{charge-style}{text|math} Style that is used to typeset the superscripts.
- Default = \code{text}
- \option{adduct-space}{<dim>} Space to the left and the right of the adduct point.
- Default = \code{.1333em}
- \option{bond-length}{<dim>} The length of the bonds. Default = \code{.5833em}
- \option{bond-offset}{<dim>} Space between bond and atoms. Default = \code{.07em}
- \option{bond-style}{<tikz>} \TikZ\ options for the bonds. Initially empty.
- \option{radical-style}{<tikz>} \TikZ\ options for the radical point. Initially
- empty.
- \option{radical-radius}{<dim>} The radius of the radical point. Default =
- \code{.2ex}
- \option{radical-hshift}{<dim>} Horizontal shift before the radical point is
- drawn. Default = \code{.15em}
- \option{radical-vshift}{<dim>} Vertical shift relative to the current baseline.
- Default = \code{.5ex}
- \option{radical-space}{<dim>} Horizontal shift after the radical point is
- drawn. Default = \code{.15em}
-\end{beschreibung}
-
-Maybe you have noticed that charges of certain ions are shifted to the right.\secidx[charges!shift]{Compounds}
-\begin{beispiel}
- \ch{SO4^2-} \ch{NH4+} \ch{Na+}
-\end{beispiel}
-They are shifted if they \emph{follow} a subscript which follows \ac{iupac}
-recommendations~\cite[][p.\,51]{iupac:greenbook}. The amount of the shift can be
-set with the option \key{charge-hshift}.
-\begin{beispiel}
- \ch{SO4^2-} \ch{NH4+} \ch{Na+} \\
- \chemsetup[chemformula]{charge-hshift=.5ex}
- \ch{SO4^2-} \ch{NH4+} \ch{Na+} \\
- \chemsetup[chemformula]{charge-hshift=.5pt}
- \ch{SO4^2-} \ch{NH4+} \ch{Na+}
-\end{beispiel}
-
-Despite \ac{iupac}'s recommendation \chemformula does not make fully staggered
-arrangements in the default setting as I find it hard to read in some cases and
-ugly in others. Since this is a subjective decision \chemformula not only let's
-you define the absolute amount of the shift but also provides a possibility for
-full staggered arrangements. For this you have to use \key{charge-hshift}{full}.
-\begin{beispiel}
- \ch[charge-hshift=0pt]{C5H11+} \ch[charge-hshift=0pt]{SO4^2-} \\
- \ch{C5H11+} \ch{SO4^2-} \\
- \ch[charge-hshift=1ex]{C5H11+} \ch[charge-hshift=1ex]{SO4^2-} \\
- \ch[charge-hshift=full]{C5H11+} \ch[charge-hshift=full]{SO4^2-}
-\end{beispiel}
-
-If you don't want the charges to be typeset in text mode you can switch to math
-mode:
-\begin{beispiel}
- \ch{M^x+} \ch{SO4^2-} \\
- \chemsetup[chemformula]{charge-style = math}
- \ch{M^x+} \ch{SO4^2-}
-\end{beispiel}
-
-The option \key{subscript-vshift} can be used to adjust the vertical shift of
-the subscripts:\secidx[subscripts!shift]{Compounds}
-\begin{beispiel}
- \ch{H2SO4} \ch{Na3PO4} \\
- \chemsetup[chemformula]{subscript-vshift=.5ex}
- \ch{H2SO4} \ch{Na3PO4} \\
- \chemsetup[chemformula]{subscript-vshift=-.2ex}
- \ch{H2SO4} \ch{Na3PO4}
-\end{beispiel}
-
-You can choose the mode subscripts are typeset in the same way as it is possible
-for the charges:
-\begin{beispiel}
- \ch{A_nB_m} \ch{H2SO4} \\
- \chemsetup[chemformula]{subscript-style = math}
- \ch{A_nB_m} \ch{H2SO4}
-\end{beispiel}
-
-The option \key{adduct-space} sets the space left and right to the adduct symbol
-$\cdot$.
-\begin{beispiel}
- \ch{Na3PO3*H2O} \\
- \chemsetup[chemformula]{adduct-space=.2em}
- \ch{Na3PO3*H2O}
-\end{beispiel}
-
-Changing the length of the bonds:\secidx[bonds!length]{Compounds}
-\begin{beispiel}
- \chemsetup[chemformula]{bond-length=4mm}%
- single: \ch{CH3-CH3} \\
- double: \ch{CH2=CH2} \\
- triple: \ch{CH+CH}
-\end{beispiel}
-
-You can change the distance between bond and atom, too:
-\begin{beispiel}
- \ch{H-H + N+N + O=O} \\
- \ch[bond-offset=1pt]{H-H + N+N + O=O}
-\end{beispiel}

- \cmd{ch}{2 Na + Cl2} \ch{2 Na + Cl2}
- \befehl{ch}{ v } \ch{v} sign for precipitate: \cmd{ch}{BaSO4 v} \ch{BaSO4 v}
- \befehl{ch}{ \lstinline+^+ } \ch{^} sign for escaping gas\footnotemark:
- \cmd{ch}{\lstinline=H2 ^=} \ch{H2 ^}
-\end{beschreibung}
-\footnotetext{Is this the correct English term? Please correct me if it isn't.}
-
-The space left and right of the plus sign can be set with this option:
-\begin{beschreibung}
- \option{plus-space}{<skip>} A rubber length. Default = \code{.3em plus .1em minus .1em}
-\end{beschreibung}
-\begin{beispiel}
- \ch{A + B}\\
- \ch[plus-space=4pt]{A + B}
-\end{beispiel}

-\subsection{Option Input}\secidx[option input]{Special Types}
-\achtung{This is an experimental feature and may well be dropped in future versions.}
-Sometimes you might want to apply an option only to a part of a, say, reaction.
-Of course you have the possibility to use \cmd{ch} several times.
-\begin{beispiel}
- \ch{H2O +}\textcolor{red}{\ch{H2SO4}}\ch{-> H3O+ + HSO4-} \\
- \ch{H2O +}\ch[subscript-vshift=2pt]{H2SO4}\ch{-> H3O+ + HSO4-}
-\end{beispiel}
-This, however, interrupts the input in your source and \emph{may} mess with the
-spacing. That's why there is an alternative:
-\begin{beschreibung}\makeatletter
- \befehl{ch}{ @\{<options>\} } The options specified this way will be valid
- \emph{only} until the next compound is set.
-\end{beschreibung}
-\begin{beispiel}
- \ch{H2O +}\textcolor{red}{\ch{H2SO4}}\ch{-> H3O+ + HSO4-} \\
- \ch{H2O + @{format=\color{red}} H2SO4 -> H3O+ + HSO4-} \\
- or of course:\\
- \ch{H2O + \textcolor{red}{H2SO4} -> H3O+ + HSO4-}\\[1em]
- \ch{H2O +}\ch[subscript-vshift=2pt]{H2SO4}\ch{-> H3O+ + HSO4-} \\
- \ch{H2O + @{subscript-vshift=2pt} H2SO4 -> H3O+ + HSO4-}
-\end{beispiel}

-\section{Escaped Input}\secidx{Escaped Input}
-In some cases it may be desirable to prevent \chemformula from parsing the input.
-This can be done in two ways.
-\subsection{Text}\label{ssec:text}\secidx[text]{Escaped Input}
-If you put something between \lstinline+" "+ or \lstinline+' '+ then the input
-will be treated as normal text, except that spaces are not allowed and have to be
-input with \lstinline+~+.
-\begin{beschreibung}
- \Befehl{ch}{ "<escaped text>" }
- \Befehl{ch}{ '<escaped text>' }
-\end{beschreibung}
-\begin{beispiel}
- \ch{"\ox{2,Ca}" O} \\
- \ch{"\ldots\," Na + "\ldots\," Cl2 -> "\ldots\," NaCl} \\
- \ch{'A~->~B'}
-\end{beispiel}
-In many cases you won't need to escape the input. But when you get into trouble
-when using a command inside \cmd{ch} try hiding it.
-
-\subsection{Math}\secidx[math]{Escaped Input}
-If you especially want to input math you just enclose it with \lstinline+$ $+.
-This output is different from the escaped text as it is followed by a space. The
-reasoning behind this is that I assume math will mostly be used to replace
-stoichiometric factors.
-\begin{beschreibung}
- \Befehl{ch}{ \string$<escaped math>\string$ }
- \Befehl{ch}{ \string\(<escaped math>\string\) }
-\end{beschreibung}
-\begin{beispiel}
- escaped text: \ch{"$x$" H2O} \\
- escaped math: \ch{$x$ H2O} \\
- also escaped math: \ch{\(x\) H2O} \\
- \ch{$2n$ Na + $n$ Cl2 -> $2n$ NaCl}
-\end{beispiel}
-
-The space that is inserted after a math group can be edited:
-\begin{beschreibung}
- \option{math-space}{<skip>} A rubber length. Default =
- \code{.1667em plus .0333em minus .0117em}
-\end{beschreibung}
-\begin{beispiel}
- \ch{$2n$ Na + $n$ Cl2 -> $2n$ NaCl} \\
- \chemsetup[chemformula]{math-space=.25em}
- \ch{$2n$ Na + $n$ Cl2 -> $2n$ NaCl} \\
- \ch{$A->B$}
-\end{beispiel}
-\secidx*{Escaped Input}
-
-\section{Arrows}\label{sec:arrows}\secidx{Arrows}
-\subsection{Arrow types}\secidx[types]{Arrows}
-Arrows are input in the same intuitive way they are with \paket{mhchem}. There
-are various different types:
-\begin{beschreibung}
- \befehl{ch}{ -> } \ch{->} standard right arrow
- \befehl{ch}{ <- } \ch{<-} standard left arrow
- \befehl{ch}{ -/> } \ch{-/>} does not react (right)
- \befehl{ch}{ </- } \ch{</-} does not react (left)
- \befehl{ch}{ <-> } \ch{<->} resonance arrow
- \befehl{ch}{ <> } \ch{<>} reaction in both directions
- \befehl{ch}{ == } \ch{==} stoichiometric equation
- \befehl{ch}{ <=> } \ch{<=>} equilibrium arrow
- \befehl{ch}{ \lstinline+<=>>+ } \ch{<=>>} unbalanced equilibrium arrow to the right
- \befehl{ch}{ \lstinline+<<=>+ } \ch{<<=>} unbalanced equilibrium arrow to the left
- \befehl{ch}{ <o> } \ch{<o>} isolobal arrow
-\end{beschreibung}
-All these arrows are drawn with \TikZ.
-\begin{beispiel}
- \ch{H2 + Cl2 -> 2 HCl} \\
- \ch{H2O + CO3^2- <=> OH- + HCO3-} \\
- \ch{A <- B} \\
- \ch{\{[CH2=CH-CH2]- <-> [CH2-CH=CH2]- \}} \\
- \ch{A <> B} \\
- \ch{H+ + OH- <=>> H2O} \\
- \ch{2 NO2 <<=> N2O4}
-\end{beispiel}
-
-\subsection{Labels}\secidx[labels]{Arrows}
-The arrows take two optional arguments to label them.
-\begin{beschreibung}
- \Befehl{ch}{ ->[<above>][<below>] }
-\end{beschreibung}
-\begin{beispiel}
- \ch{A ->[a] B} \\
- \ch{A ->[a][b] B} \\
- \ch{A ->[\SI{100}{\celsius}] B}
-\end{beispiel}
-The label text can be parsed seperately from the arrow. The recipe is easy: leave
-blanks.
-\begin{beispiel}
- \ch{A ->[H2O] B} \\
- \ch{A ->[ H2O ] B} \\
- \ch{A ->[ "\ox{2,Ca}" F2 ] B} \\
- \ch{A ->[$\Delta$,~ \[H+ \]] B}
-\end{beispiel}
-If you leave the blanks \chemformula treats the groups inside the square brackets
-as seperated input types. The arrow reads its arguments \emph{afterwards}. As you
-can see the arrows \enquote{grow} with the length of the labels. What stays
-constant is the part that protrudes the labels. As you also can see in the last
-example square brackets inside the arrow arguments should be produced using \cmd{[}
-and \cmd{]}. They keep their usual meaning outside \cmd{ch}. These commands are
-necessary since the usual grouping (\ie hiding the brackets inside curly brackets)
-doesn't work due to the way \cmd{ch} reads its argument.
-\begin{beispiel}
- \ch{A ->[a] B} \\
- \ch{A ->[ab] B} \\
- \ch{A ->[abc] B} \\
- \ch{A ->[abc~abc] B} \\
- % needs the `chemfig' package:
- \setatomsep{15pt}
- \ch{A ->[ "\chemfig{-[:30]-[:-30]OH}" ] B} \\
- \ch{A ->[[]] B} vs. \ch{A ->[\[\]] B}
-\end{beispiel}
-
-\subsection{Customization}\secidx[customization]{Arrows}
-These are the options which enable you to customize the arrows:
-\begin{beschreibung}
- \option{arrow-offset}{<dim>} This is the length that an arrow protrudes a label
- on both sides. This means an empty arrow's length is two times \code{arrow-offset}.
- Default = \code{.75em}
- \option{arrow-min-length}{<dim>} The minimal length an error must have unless
- two times \key{arrow-offset} plus the width of the label is larger.
- Default = \code{0pt}
- \option{arrow-yshift}{<dim>} Shifts an arrow up (positive value) or down (negative
- value). Default = \code{0pt}
- \option{arrow-ratio}{<factor>} The ratio of the arrow lengths of the unbalanced
- equilibrium. \code{.4} would mean that the length of the shorter arrow is
- $0.4\times$ the length of the longer arrow. Default = \code{.6}
- \option{compound-sep}{<dim>} The space between compounds and the arrows.
- Default = \code{.5em}
- \option{label-offset}{<dim>} The space between the labels and the arrows.
- Default = \code{2pt}
- \option{label-style}{<font command>} The relative font size of the labels.
- Default = \lstinline+\footnotesize+
-\end{beschreibung}
-
-The following code shows the effect of the different options on the \lstinline+<=>>+
-arrow:
-\begin{beispiel}
- standard: \ch{A <=>>[x][y] B} \\
- longer: \ch[arrow-offset=12pt]{A <=>>[x][y] B} \\
- higher: \ch[arrow-yshift=2pt]{A <=>>[x][y] B} \\
- more balanced: \ch[arrow-ratio=.8]{A <=>>[x][y] B} \\
- labels further away: \ch[label-offset=4pt]{A <=>>[x][y] B} \\
- larger distance to compounds: \ch[compound-sep=2ex]{A <=>>[x][y] B} \\
- smaller labels: \ch[label-style=\tiny]{A <=>[x][y] B}
-\end{beispiel}
-
-\subsection{Modify Arrow Types}\label{sec:arrows_modify}\secidx[types!modify]{Arrows}
-The arrows are defined with the command
-\begin{beschreibung}
- \Befehl{DeclareChemArrow}{<tokens>}\ma{<tikz>}
-\end{beschreibung}
-\ma{<tokens>} is the sequence of tokens that is replaced with the actual arrow code.
-For example the basic arrow is defined via
-\begin{beispiel}[code only]
- \DeclareChemArrow{->}{\draw[-cf] (cf_arrow_start) -- (cf_arrow_end) ;}
-\end{beispiel}
-In order to define arrows yourself you need to know the basics of \TikZ\footnote{Please
-see the \textsf{pgfmanual} for details.}. There are some predefined coordinates
-you can and should use:
-\begin{description}
- \item[\code{(cf\_arrow\_start)}] The beginning of the arrow.
- \item[\code{(cf\_arrow\_end)}] The end of the arrow.
- \item[\code{(cf\_arrow\_mid)}] The mid of the arrow.
- \item[\code{(cf\_arrow\_mid\_start)}] The beginning of the shorter arrow in
- types like \lstinline+<=>>+.
- \item[\code{(cf\_arrow\_mid\_end)}] The end of the shorter arrow in types like
- \lstinline+<=>>+.
- \item[\code{cf}, \code{left cf}, \code{right cf}] \chemformula's own arrow heads.
-\end{description}
-\begin{beispiel}
- \DeclareChemArrow{.>}{\draw[-cf,dotted,red] (cf_arrow_start) -- (cf_arrow_end);}
- \DeclareChemArrow{n>}{\draw[-cf] (cf_arrow_start) .. controls ([yshift=3ex]cf_arrow_mid) .. (cf_arrow_end);}
- \ch{A .> B} \ch{A .>[a][b] B} \ch{A n> B}
-\end{beispiel}
-If you want to redefine an existing arrow there are two commands you can use:
-\begin{beschreibung}
- \Befehl{RenewChemArrow}{<tokens>}\ma{<tikz>}
- \Befehl{ShowChemArrow}{<tokens>}
-\end{beschreibung}
-The second one gives the current definition, the first one redefines an existing
-arrow.
-\begin{beispiel}
- \texttt{\ShowChemArrow{->}} \\
- \RenewChemArrow{->}{\draw[->,red] (cf_arrow_start) -- (cf_arrow_end) ;}
- \texttt{\ShowChemArrow{->}} \\
- \ch{A -> B}
-\end{beispiel}
-\secidx*{Arrows}
-
-\section{Names}\secidx{Names}
-\subsection{Syntax}\secidx[syntax]{Names}
-\chemformula has a built-in syntax to write text under a compound. In a way it
-works very similar to the arrows.
-\begin{beschreibung}
- \Befehl{ch}{ !(<name>)( <formula> ) }
-\end{beschreibung}
-If an exclamation mark is followed by a pair of parentheses \chemformula will
-parse it this way:
-\begin{beispiel}
- \ch{!(ethanol)( CH2CH2OH )}
-\end{beispiel}
-The same what's true for the arrows arguments holds for these arguments: if you
-leave blanks the different parts will be treated according to their input type
-before the text is set below the formula.
-\begin{beispiel}
- \ch{!(water)(H2O)} \quad
- \ch{!( "\textcolor{blue}{water}" )( H2O )} \quad
- \ch{!( $2n-1$ )( H2O )} \quad
- \ch{!( H2O )( H2O )} \quad
- \ch{!(oxonium)( H3O+ )}
-\end{beispiel}
-If for some reason you want to insert an exclamation mark \emph{without} it
-creating a name you only have to make sure it isn't followed by parentheses.
-\begin{beispiel}
- \ch{H2O~(!)} \\
- \ch{A!{}()}
-\end{beispiel}
-
-\subsection{Customization}\secidx[customization]{Names}
-\chemformula provides two options to customize the output of the names:
-\begin{beschreibung}
- \option{name-format}{<commands>} The format of the name. This can be arbitrary
- input. Default = \lstinline+\scriptsize\centering+
- \option{name-width}{<dim>|auto} The width of the box where the label is put into.
- \code{auto} will detect the width of the name and set the box to this width.
- Default = \code{auto}
-\end{beschreibung}
-\begin{beispiel}
- \ch{!(acid)( H2SO4 ) -> B} \\
- \ch[name-format=\sffamily\small]{!(acid)( H2SO4 ) -> B} \\
- \ch[name-format=\scriptsize N:~]{!(acid)( H2SO4 ) -> B} \\
- \ch[name-width=3em,name-format=\scriptsize\raggedright]{!(acid)( H2SO4 ) -> B}
-\end{beispiel}
-\secidx*{Names}
-
-\section{Format and Font}\secidx{Format and Font}\label{sec:format}
-In the standard setting \chemformula doesn't make any default changes to the font
-of the formula output. Let's take a look at a nonsense input which shows all features:
-\begin{beispiel}
- \newcommand*\sample{\ch{H2C-C+C-CH=CH+ + CrO4^2- <=>[x][y] 2.5 Cl^{-.} + 3_1/2 Na*OH_{(aq)} + !(name)( A^n ) "\LaTeXe"}}
- \sample
-\end{beispiel}
-\newcommand*\sample{\ch{H2C-C+C-CH=CH+ + CrO4^2- <=>[x][y] 2.5 Cl^{-.} + 3_1/2 Na*OH_{(aq)} + !(name)( A^n ) "\LaTeXe"}}
-Now we're going to change different aspects of the font a look what happens:
-\begin{beispiel}[below]
- \sffamily Hallo \sample \\
- \ttfamily Hallo \sample \normalfont \\
- \bfseries Hallo \sample \normalfont \\
- \itshape Hallo \sample
-\end{beispiel}
-As you can see most features adapt to the surrounding font.
-
-If you want to change the default format you need to use this option:
-\begin{beschreibung}
- \option{format}{<anything>} Adds arbitrary code before the output of \cmd{ch}.
-\end{beschreibung}
-\begin{beispiel}
- \definecolor{newblue}{rgb}{.1,.1,.5}\chemsetup[chemformula]{format=\color{newblue}\sffamily}
- \sffamily Hallo \sample \\
- \ttfamily Hallo \sample \normalfont \\
- \bfseries Hallo \sample \normalfont \\
- \itshape Hallo \sample
-\end{beispiel}
-
-You can also specifically change the fontfamily, fontseries and fontshape of the output.
-\begin{beschreibung}
- \option{font-family}{<family>} Changes the fontfamily of the output with
- \lstinline+\fontfamily{<family>}\selectfont+.
- \option{font-series}{<series>} Changes the fontseries of the output with
- \lstinline+\fontseries{<series>}\selectfont+.
- \option{font-shape}{<shape>} Changes the fontshape of the output with
- \lstinline+\fontshape{<shape>}\selectfont+.
-\end{beschreibung}
-\begin{beispiel}
- \chemsetup[chemformula]{font-series=bx}
- Hallo \sample \\
- \sffamily Hallo \sample \normalfont \\
- \chemsetup[chemformula]{font-family=lmr,font-series=m} Hallo \sample \normalfont \\
- \itshape Hallo \sample
-\end{beispiel}
-
-If you're using \hologo{XeLaTeX} or \hologo{LuaLaTeX} and have loaded \paket{fontspec}
-you have the possibilty to set the font with it:
-\begin{beschreibung}
- \Option{font-spec}{\{<font>\}} or with options
- \Option{font-spec}{\{[<options>]<font>\}}
-\end{beschreibung}
-\begin{beispiel}
- \chemsetup[chemformula]{font-spec={Linux Biolinum O}} \sample \\
- \chemsetup[chemformula]{font-spec={[Color=darkgray]Augie}} \sample \\
- \chemsetup[chemformula]{font-spec={Tipbrush Script}} \sample \\
- \chemsetup[chemformula]{font-spec={Latin Modern Sans}} \sample \\
- \bfseries \sample \normalfont \\
- \chemsetup[chemformula]{font-spec={Feathergraphy Decoration}} \sample

-\section{Usage In Math Equations}\secidx{Math Environments}
-The \cmd{ch} command can be used inside math equations. It recognizes
-\lstinline+\\+ and \lstinline+&+ and passes them on. However, you can't use the
-optional arguments of \lstinline+\\+ inside \cmd{ch}.
-\begin{beispiel}
- \begin{align}
- \ch{
- H2O & ->[a] H2SO4 \\
- Cl2 & ->[x][y] CH4
- }
- \end{align}
- \begin{align*}
- \ch{
- RNO2 &<=>[ + e- ] RNO2^{-.} \\

-\section{Get Hazard and Precautionary Statements}\secidx{Hazard and Precautionary Statements}
-\subsection{Simple Statements}\secidx[get statements]{GHSYSTEM}
-The general usage is simple: you use the command
-\begin{beschreibung}
- \Befehl{ghs}*[<options>]{<type>}\ma{<number>}
-\end{beschreibung}
-There are three types available: \code{h}, \code{euh} and \code{p}. The \ma{<type>}
-argument is case insensitive, so just type them in as you like.
-\begin{beispiel}
- \ghs{h}{200} \\
- \ghs{H}{224} \\
- \ghs{euh}{001} \\
- \ghs{Euh}{202} \\
- \ghs{p}{201}
-\end{beispiel}
-
-The starred version hides the identifier and only gives the statement. If you want
-to hide the statement itself instead you can use the option:
-\begin{beschreibung}
- \Option{hide}{\default{true}|false}
-\end{beschreibung}
-
-There is an option to customize the output, too.
-\begin{beschreibung}
- \option{space}{<space command>} Space between \code{<type>} and \code{<number>}.
-\end{beschreibung}
-\begin{beispiel}
- \ghs{h}{200} \\
- \ghs[space=\,]{h}{200} \\
- \ghs*{h}{200} \\
- \ghs[hide]{h}{200}
-\end{beispiel}
-
-\subsection{Statements with Placeholders}\secidx[statements with placeholders]{GHSYSTEM}
-Some of the statements contain placeholders. They can be one of the following:
-\begin{itemize}
- \item \textit{\textless state route of exposure if it is conclusively proven that
- no other routes of exposure cause the hazard\textgreater}
- \item \textit{\textless state specific effect if known\textgreater}
- \item \textit{\textless or state all organs affected, if known\textgreater}
- \item \textit{\textless name of sensitising substance\textgreater}
-\end{itemize}
-
-Except the last one which needs to be filled in, they are hidden per default. They
-can be made visible with the option
-\begin{beschreibung}
- \option{fill-in}{\default{true}|false} Show placeholders. Default = \code{false}
-\end{beschreibung}
-\begin{beispiel}[below]
- \ghs{h}{340} \\
- \ghs[fill-in]{h}{340} \\
- \ghs{h}{360} \\
- \ghs[fill-in]{h}{360} \\
- \ghs{h}{370} \\
- \ghs[fill-in]{h}{370} \\
- \ghs{euh}{208} \\
- \ghs[fill-in]{euh}{208}
-\end{beispiel}
-
-These placeholders can be replaced with one of these options:
-\begin{beschreibung}
- \option{exposure}{<text>} exposure placeholder
- \option{effect}{<text>} effect placeholder
- \option{organs}{<text>} organ placeholder
- \option{substance}{<text>} substance placeholder
-\end{beschreibung}
-\begin{beispiel}
- \ghs[exposure=This is how you get exposed.]{h}{340} \\
- \ghs[effect=These are the effects.]{h}{360} \\

- \ghs{p}{301} \\
- \ghs{p}{401} \\
- \ghs{p}{411} \\
- \ghs{p}{413}
-\end{beispiel}
-
-These gaps can be filled using these options:
-\begin{beschreibung}
- \Option{text}{<text>}
- \Option{dots}{<text>}
- \Option{C-temperature}{<num>}
- \Option{F-temperature}{<num>}
- \Option{kg-mass}{<num>}
- \Option{lbs-mass}{<num>}
-\end{beschreibung}
-\begin{beispiel}
- \ghs[text=contact physician!]{p}{301} \\
- \ghs[dots=here]{p}{401} \\
- \ghs[C-temperature=50, F-temperature=122]{p}{411} \\

-\subsection{The Pictures}
-The \ac{ghs} defines a number of pictograms:
-
-\ghspic{explos} \ghspic{flame} \ghspic{flame-O} \ghspic{bottle} \ghspic{acid}
-\ghspic{skull} \ghspic{exclam} \ghspic{health} \ghspic{aqpol}
-
-The command
-\begin{beschreibung}
- \Befehl{ghspic}[<options>]{<name>}
-\end{beschreibung}
-loads them. Table~\ref{tab:ghs_pictograms} shows all available pictograms and their
-names. To be more precise: it shows the names to use with the \cmd{ghspic} command.
-The file names are \lstinline=ghsystem_<name>.<filetype>= where \code{<filetype>}
-is \code{eps}, \code{pdf}, \code{jpg} or \code{png}, see also section~\ref{ssec:picture_type}.
-\begin{beispiel}
- \ghspic{skull}
-\end{beispiel}
-
-If you don't like the default size you can change it using this option:
-\begin{beschreibung}
- \option{scale}{<factor>} Scales the pictogram. Default = \code{1}
-\end{beschreibung}
-The pictures are actually quite large. The default setting scales them by a factor
-of $\frac{1}{20}$.
-\begin{beispiel}
- \ghspic[scale=2]{skull}
-\end{beispiel}
-
-If you want to use some specific \lstinline=\includegraphics= options, \eg if you
-want to rotate the pictogram for some reason, use this option:
-\begin{beschreibung}
- \Option{includegraphics}{\{<includegraphics keyvals>\}}
-\end{beschreibung}
-\begin{beispiel}
- \ghspic[includegraphics={angle=90}]{skull}

-\subsection{Picture Type Depending on Engine}\label{ssec:picture_type}
-As you probably know you can't use every picture type with every compiler engine.
-\pdfTeX{} in \acs{dvi} mode \emph{needs} \code{eps} pictures while
-\pdfTeX{} in \acs{pdf} mode, \XeTeX{} and \LuaTeX{} convert
-\code{eps} pictures into \code{pdf} files, given they have the rights to write in
-the directory the pictures are saved in.
-
-However, the latter can include \code{jpg} and \code{png} without any problems,
-while \pdfTeX{} in \acs{dvi} mode can't.
-
-To resolve this \ghsystem tests which engine is used and if \pdfTeX{} which
-mode is used and then chooses either \code{eps} or \code{pdf} for the pictograms.
-You are free to choose the picture type yourself with the option
-\begin{beschreibung}
- \Option{pic-type}{eps|pdf|jpg|png}
-\end{beschreibung}
-\secidx*{Pictograms}
-
-\section{Available Languages}\label{sec:ghsystem_language}
-Right now the H and P statements are only available in English, German or Italian.
-The package adapts the package option \key[option]{german} but does not (yet)
-recognize language settings by \paket{babel} or \paket{polyglossia}.
-
-You can also choose the language explicitly.
-\begin{beschreibung}
- \Option{language}{english|german|italian}
-\end{beschreibung}
-\begin{beispiel}
- \ghs{h}{201}
-
- \chemsetup[ghsystem]{language=german}
- \ghs{h}{201}
-\end{beispiel}
-
-I will add other languages some time in future. This may take a while, though.
-If you would be willing to contribute and write the statements of another language
-please feel free to contact me\footnote{\href{mailto:contact@mychemistry.eu}{contact@mychemistry.eu}}.
-I would provide you with a template file, a \acs{pdf} containing the official
-translations, and help to all your questions.

-\section{List of All Statements}\secidx{List of All Statements}
-If for some reason you want to list all sentences you can use
-\begin{beschreibung}
- \Befehl{ghslistall}[<options>]
-\end{beschreibung}
-
-This command has a number of options to customize the table, which is created with
-the \lstinline=longtable= environment of the \paket{longtable} package.
-\begin{beschreibung}
- \option{table-head-number}{<text>} Default = \code{Identifier}
- \option{table-head-text}{<text>} Default = \code{Statement}
- \option{table-next-page}{<text>} Default = \code{continues on next page}
- \option{table-caption}{<text>} As \code{<text>} in \lstinline=\caption{<text>}=.
- Default = \code{All H, EUH, and P Statements.}
- \option{table-caption-short}{<text>} As \code{<short>} in \lstinline=\caption[<short>]{<text>}=.
- \option{table-label}{<text>} The label to refer to the table with \lstinline=\ref=
- and similar commands. Default = \code{tab:ghs-hp-statements}
- \option{table-row-sep}{<dim>} The separation of the table rows. A \TeX\ dimension.
- Default = \code{3pt}
- \option{table-rules}{\default{default}|booktabs|none} The style of the horizontal
- rules in the table. \code{default} uses \lstinline=\hline=, \code{booktabs} uses
- \lstinline=\toprule=, \lstinline=\midrule= or \lstinline=\bottomrule=, resp.
- This option needs the \paket{booktabs} package which you have to load yourself
- then. Default = \code{default}
- \option{table-top-head-rule}{\default{default}|booktabs|none} Change top rule
- explicitly. Default = \code{default}
- \option{table-head-rule}{\default{default}|booktabs|none} Change rule below head
- explicitly. Default = \code{default}
- \option{table-foot-rule}{\default{default}|booktabs|none} Change foot rule
- explicitly. Default = \code{default}
- \option{table-last-foot-rule}{\default{default}|booktabs|none} Change last foot
- rule explicitly. Default = \code{default}
-\end{beschreibung}
-
-The code below shows how table~\ref{tab:ghs-hp-statements} was created:
-\begin{beispiel}[code only]
- \ghslistall[fill-in,table-rules=booktabs]
-\end{beispiel}
-
-\ghslistall[fill-in,table-rules=booktabs]
-\secidx*{List of All Statements}\secidx*{GHSYSTEM}
+This change has been made \sinceversion{4.0}with version~4.0 since with this
+version every of those packages can be used independently from the
+\chemmacros\ package. It made sense to give each of them an own documentation
+file. You should be able to find them in the same folder as this document as
+well as via the \code{texdoc} program. You can also try and click on the
+names in the list above. They are links and \emph{should} open the respective
+file.

-\section{Licenza, requisiti e LEGGIMI}
-Il bundle \chemmacros è pubblicato sotto la \LaTeX\ Project Public License
-(LPPL) versione 1.3 o successive (\url{http://www.latex-project.org/lppl.txt})
-ed ha lo stato \enquote{maintained}.
-
-Il bundle \chemmacros richiede versioni attuali dei bundle \paket{l3kernel} e
-\paket{l3packages}. Inoltre sono richiesti i pacchetti \paket{siunitx},
-\paket{mathtools}, \paket{bm}, \paket{nicefrac} ed \paket{environ} come anche
-\paket*{tikz}\footnote{CTAN:~\href{http://www.ctan.org/pkg/pgf/}{pgf}} e le sue
-librerie \code{calc} e \code{arrows}.
-
-L'opzione globale del pacchetto (d'ora in poi indicata come \enquote{opzione
-globale}) \key{bpchem} (vedi paragrafo~\ref{sec:optionen}) richiede
-\paket{bpchem}, l'opzione globale \key{xspace} richiede \paket{xspace} e l'opzione
-globale \key{method}{mhchem} richiede \paket{mhchem}.
-
-Dalla v3.0 il pacchetto \chemmacros è stato riunito con i nuovi pacchetti
-\chemformula e \ghsystem; \chemformula è un'alternativa a \paket{mhchem}. Questo
-ha portato ad alcuni cambiamenti interni a \chemmacros. Contemporaneamente è
-stato totalmente rielaborato questo manuale.
-
-Forse l'utente ricorderà che le opzioni di \chemmacros appartengono tutte a
-moduli diversi (per ulteriori informazioni a riguardo vedi il paragrafo~%
-\ref{sec:setup}). Questi vengono poste nel margine sinistro quando l'opzione
-viene citata per la prima volta. L'appendice (vedi la parte~\ref{sec:overview})
-elenca tutte le opzioni di \chemmacros e i rispettivi moduli. In questo documento
-le opzioni sono contrassegnate dal colore \textcolor{key}{\code{verde}} e i moduli
-dal colore \textcolor{module}{\code{rosso}}.
-
-Il pacchetto \ghsystem richiede i pacchetti \chemmacros, \paket{tabu},
-\paket{longtable}, \paket{ifpdf} e \paket{graphicx}. %\ghsystem non ha opzioni
-%sdi pacchetto proprie ma passa tutte le opzioni a \chemmacros.
-
-\achtung{Il pacchetto riconosce alcuni comandi e opzioni obsolete, che non
-vengono più descritti in questo manuale; sono ancora definiti per garantire la
-compatibilità con documenti meno recenti. Questi comandi restituiscono un
-avviso; in futuro potrebbero non essere più definiti.}
-
-\section{Motivazioni e ragioni}
-\chemmacros nacque qualche anno fa come una lista crescente di macro che usavo
-frequentemente. Non ricordo più il momento e le ragioni che mi spinsero a
-pubblicarle come pacchetto. Ora lo avete davanti a voi \textendash\ spero che
-anche voi riusciate a trarne qualche beneficio.
-
-Nel corso del tempo le macro ed il loro funzionamento sono leggermente variati,
-e se ne sono aggiunte di nuove. Con il passare del tempo molte cose si sono
-unificate, introducendo sempre più possibilità di apportare personalizzazioni.
-
-Ogni chimico che usi \LaTeX\ per la compilazione dei propri documenti conoscerà
-il meraviglioso pacchetto \paket{mhchem} di Martin Hensel. Fin dall'inizio vi
-furono delle difficoltà a fare cooperare \paket{mhchem} e \chemmacros.
-Alcuni dettagli di \paket{mhchem} non mi hanno mai soddisfatto particolarmente,
-ma non sembravano essere sufficienti per un nuovo pacchetto, nemmeno per inviare
-un \enquote{feature request} all'autore di \paket{mhchem}. La sfida e il
-divertimento nel creare un pacchetto nuovo nonché il desiderio di raggiungere
-una flessibilità massima hanno infine portato a \chemformula.
-
-\chemformula funziona in modo analogo a \paket{mhchem}, ma è più severo per quanto
-riguarda l'input di composti, fattori stechiometrici e frecce di reazione;
-contemporaneamente \chemformula offre alcune possibilità di adattare l'output che
-\paket{mhchem} non ha. Dato che \chemformula nasce come alternativa a
-\paket{mhchem}, \chemmacros offre un'opzione per selezionare uno tra
-\paket{mhchem} e \chemformula.
-
-Il lettore di formazione chimica probabilmente sarà a conoscenza che le
-\acl{UN} hanno introdotto il \ac{ghs} come sostituto di validità
-globale per i numerosi sistemi dei diversi paesi, simili ma non unitari. Nonostante
-non sia ancora stato adottato da tutti i paesi \cite{unece:ghsystem_implementation},
-questo avverrà ben presto. Il pacchetto \ghsystem offre la possibilità di inserire
-e richiamare in modo semplice tutti gli \enquote{hazard and precautionary statements}.
-Le frasi sono tratte dal regolamento CE 1272/2008 \cite{eu:ghsystem_regulation}.
-
-Con questo bundle spero di essere riuscito a realizzare i seguenti quattro punti:
-\begin{itemize}
- \item permettere un utilizzo intuitivo, soprattutto per quanto riguarda la
- sintassi dei comandi;
- \item proporre dei comandi non solo per semplificare la stesura ma anche la
- lettura del codice, migliorandone la semantica e rendendola più logica
- (\lstinline=\ortho-diclorobenzene= è più leggibile e più comprensibile di
- \lstinline=\textsl{o}-diclorobenzene=);
- \item introdurre flessibilità e adattabilità ove possibile, in modo che ogni
- utente possa adattare i comandi alle proprie necessità;
- \item usare impostazioni predefinite conformi alle norme e le indicazioni della \ac{iupac}.
-\end{itemize}
-L'ultimo punto in particolare ha richiesto qualche incitamento da parte degli
-utenti\footnote{Molte grazie al Dr.~Paul~King!} per applicare le
-impostazioni giuste in numerosi punti. Se doveste notare qualcosa che non
-corrisponde ai consigli \ac{iupac}\footnote{Questo non vale per il comando \cmd{ox}.
-La versione \ac{iupac} è \cmd[oxa]{ox*}.} sarei molto grato di una notifica via
-e-mail!
-
-In un pacchetto di questa mole comprendente parti meno e più recenti (le ultime
-debbono essere considerate ancora in fase beta) non è possibile evitare la
-presenza di errori o bug. Ho grande interesse a correggere e migliorare questo
-pacchetto, e quindi prego tutti gli utenti che notino un funzionamento imprevisto
-o indesiderato (anche se apparentemente insignificante) di mandarmi un'e-mail, e
-vedrò di fare quel che posso. Sono particolarmente interessato a feedback
-riguardante \chemformula (vedi la parte~\ref{part:chemformula}) e \ghsystem (vedi
-la parte~\ref{part:ghsystem}), ma sono felice di ricevere feedback anche su
-qualunque altra parte del bundle.

-\section{Installazione e caricamento del bundle}\secidx{Caricamento del
-bundle}\secidx{Installazione}
-Il bundle contiene tre fogli di stile\footnote{Con l'estensione \code{sty}.}, una
-cartella di nome \code{language/} che contiene i file di definizione di lingua per
-il GHS (estensione \code{def}) e una cartella di nome \code{pictures/} che
-contiene immagini di tipo \code{eps}, \code{pdf}, \code{jpg} e \code{png} (i
-pittogrammi GHS). Nel caso di un'installazione manuale \emph{è necessario copiare
-le cartelle \code{language/} e \code{pictures/} nella \emph{stessa} cartella dei
-fogli di stile}.
-
-Il caricamento di \chemmacros via
-\begin{beispiel}[code only]
- \usepackage{chemmacros} % `chemmacros', `chemformula' and `ghsystem' are loaded
-\end{beispiel}
-carica anche \chemformula e \ghsystem. È tuttavia possibile impedire a \chemmacros
-di caricare \ghsystem:
-\begin{beispiel}[code only]
- \usepackage[ghsystem=false]{chemmacros} % `chemmacros' and `chemformula' are loaded
-\end{beispiel}
-Il caricamento di \chemformula non può essere evitato a causa dell'interazione tra
-\chemmacros e \chemformula.
-
-Il caricamento esplicito di \chemformula o \ghsystem è possibile e carica
-contemporaneamente anche \chemmacros, se non ancora caricato; implicitamente
-quindi si caricano a vicenda.
-\begin{beispiel}[code only]
- \usepackage{chemformula}
- or
- \usepackage{ghsystem}
-\end{beispiel}
-
-Si consiglia tuttavia di utilizzare solamente \lstinline=\usepackage{chemmacros}=
-e di applicare le opzioni desiderate con \lstinline=\chemsetup= (confronta il
-paragrafo~\ref{sec:setup}).
-\secidx*{Installazione}\secidx*{Caricamento del pacchetto}
-
-\section{Opzioni globali}\label{sec:optionen}\secidx{Opzioni globali}
-\chemmacros ha diverse opzioni, che seguono tutte il principio chiave/valore:
-\begin{beispiel}[code only]
- \usepackage[option1 = <value1>, option2 = <value2>]{chemmacros}
-\end{beispiel}
-La maggior parte delle opzioni può essere richiamata anche senza assegnargli un
-valore (\lstinline+\usepackage[option]{chemmacros}+); in questo caso richiamano il
-valore \default{sot\-to\-li\-ne\-a\-to}.
-
-Sia \chemformula che \ghsystem non hanno opzioni di pacchetto proprie; se caricati
-esplicitamente, perdono tutte le opzioni passate loro, che devono poi essere
-impostate con il comando di setup.
-\chemmacros.
-\begin{beschreibung}
- % bpchem
- \option[option]{bpchem}{\default{true}|false} Questa opzione carica \paket{bpchem}
- e adatta il layout di \cmd{NMR} ai comandi propri di \paket{bpchem}
- \lstinline+\HNMR+ e \lstinline+\CNMR+. Default = \code{false}
- % circled
- \option[option]{circled}{\default{formal}|all|none} \chemmacros distingue due
- tipi di cariche:\footnote{Ringrazio Christoph Schäfer per avermi fatto notare
- che la v1.1 trattava le cariche in modo poco coerente!} le cariche reali ($+/-$)
- e quelle formali (\fplus/\fminus). L'opzione \code{formal} distingue tra i
- due tipi, \code{all} le rappresenta tutte cerchiate, \code{none} tutte senza
- cerchio. Default = \code{formal}
- % circletype
- \option[option]{circletype}{\default{chem}|math} Questa opzione varia tra due
- rappresentazioni per le cariche formali: \cmd{fplus} \fplus\ e
- \lstinline+$\oplus$+ $\oplus$. Default = \code{chem}
- % cmversion
- \option[option]{cmversion}{1|2|bundle} Questa opzione ripristina le definizioni
- di alcuni comandi, in modo da compilare correttamente documenti composti
- utilizzando v1.*. Default = \code{bundle}; in realtà \code{2} e \code{bundle}
- sono equivalenti. L'opzione può essere impostata solamente nel preambolo.
- % ghsystem
- \option[option]{ghsystem}{\default{true}|false} Attiva/disattiva il pacchetto
- \ghsystem. L'impostazione \key{ghs}{false} sopprime il caricamento di \ghsystem.
- Default = \code{true}
- % greek
- \option[option]{greek}{auto|math|textgreek|\default{upgreek}} Questa opzione
- determina come vengono rappresentate la lettera \cmd{Chemalpha} e le sue simili
- (vedi a pagina~\pageref{desc:upgreek} per ulteriori informazioni). L'opzione
- può essere impostata solo nel preambolo. Nota bene: l'opzione non carica né
- \paket{upgreek} né \paket{textgreek}, bensì determina solamente quale dei due
- viene utilizzato, se caricato. Scegliendo \code{upgreek}, è necessario
- \emph{anche} caricare il pacchetto corrispondente.
- Default = \code{auto}
- % iupac
- \option[option]{iupac}{auto|restricted|strict} Determina le impostazioni dei comandi
- di nomenclatura (vedi a pagina~\pageref{desc:iupac}). Default = \code{auto}
- % language
- \option[option]{language}{american|british|english|french|german|italian|ngerman}
- Carica impostazioni specifiche per una lingua. \code{english}, \code{american}
- e \code{british} sono tra loro equivalenti, come anche \code{german} e \code{ngerman}.
- L'opzione può essere impostata solo nel preambolo. Default = \code{english}
- % method
- \option[option]{method}{\default{chemformula}|mhchem} È possibile scegliere tra
- \paket{mhchem} e \chemformula per gli ambienti di reazione di \chemmacros (vedi
- il paragrafo~\ref{sec:reactions}) e per le particelle (vedi il paragrafo~\ref{sec:teilchen}).
- Default = \code{chemformula}. L'opzione può essere impostata solo nel preambolo.
- % Nu
- \option[option]{Nu}{\default{chemmacros}|mathspec} Anche il pacchetto \paket{mathspec}
- definisce una macro \cmd{Nu}; questa opzione decide quale definizione verrà
- applicata (vedi a pagina~\pageref{Nu}). Default = \code{chemmacros}. L'opzione
- può essere impostata solo nel preambolo.
- % strict
- \option[option]{strict}{\default{true}|false} L'impostazione \key{strict}{true}
- trasforma tutti gli avvisi in messaggi di errore. Default = \code{false}
- % synchronize
- \option[option]{synchronize}{\default{true}|false} Impostando \code{true}, se
- \chemformula è stato scelto come metodo \chemmacros ne adotta le impostazioni
- di carattere. Default = \code{false}. Per dimostrare il funzionamento di questa
- opzione, il documento è stato compilato con \key{synchronize}{true} e l'impostazione
- di \chemformula \lstinline+\chemsetup[chemformula]{font-spec={[Color=darkgray]Latin Modern Sans}}+.
- % xspace
- \option[option]{xspace}{\default{true}|false} Con questa opzione la maggior parte
- delle macro comprende un \lstinline+\xspace+. Default = \code{true}
-\end{beschreibung}

-\section{Setup}\label{sec:setup}\secidx{Setup}
-Numerosi comandi di \chemmacros, \chemformula e \ghsystem hanno come opzioni delle
-coppie chiave/valore attraverso le quali possono essere adattate. Tipicamente
-possono essere utilizzate come argomento (opzionale) del comando, e in genere anche
-con il comando \cmd{chemsetup}.
-\begin{beschreibung}
- \Befehl{chemsetup}[<module>]{<key> = <value>} oppure
- \Befehl{chemsetup}{<module>/<key> = <value>}
-\end{beschreibung}
-Quasi tutte le opzioni appartengono ad un modulo, che indica quale comando vanno
-ad influenzare. Quando viene presentata un'opzione, il suo modulo di appartenenza
-viene qui segnato nel margine sinistro. Con il comando \cmd{chemsetup} è possibile
-utilizzare le opzioni in due modalità diverse, come mostrato sopra.
-
-Le opzioni globali possono essere considerate anche come opzioni appartenenti al
-modulo \textcolor{module}{\ttfamily option}; possono essere quindi richiamate anche
-da \cmd{chemsetup}.
-\begin{beispiel}
- \chemsetup[option]{circled=none}\mch\ \pch\ \fmch\ \fpch\ \el\ \prt \\
- \chemsetup[option]{circled=formal}\mch\ \pch\ \fmch\ \fpch\ \el\ \prt \\
- \chemsetup[option]{circletype=math}\mch\ \pch\ \fmch\ \fpch\ \el\ \prt \\
- \chemsetup{option/circletype=chem,option/circled=all}\mch\ \pch\ \fmch\ \fpch\ \el\ \prt \\
- \chemsetup{option/circletype=math}\mch\ \pch\ \fmch\ \fpch\ \el\ \prt
-\end{beispiel}
-Le opzioni che non appartengono a nessun modulo \emph{non possono essere utilizzate}
-con \cmd{chemsetup}!
-
-Tutte le opzioni di \chemformula appartengono al modulo \textcolor{module}{\code{chemformula}},
-e tutte le opzioni di \ghsystem appartengono al modulo \textcolor{module}{\code{ghs}}.

-\label{desc:upgreek}Le lettere greche non sono comandi nuovi: la loro definizione
-dipende dai pacchetti caricati. La loro versione predefinita corrisponde alle lettere
-greche corsive proprie del modo matematico. Se è caricato il pacchetto \paket{textgreek},
-vengono utilizzate le sue lettere; se è caricato il pacchetto \paket{upgreek},
-vengono utilizzate le lettere di quest'ultimo. Questo manuale impiega \paket{upgreek}.
-Quando sono caricati entrambi \paket{textgreek} e \paket{upgreek}, viene impiegato
-automaticamente \paket{upgreek}.
-
-Nel caso in cui l'utente non voglia adattarsi alla selezione automatica di \chemmacros,
-per scegliere autonomamente va impiegata l'opzione globale \key[option]{greek}.
-La tabella~\ref{tab:upgreek_mode} mostra le diverse varianti di alcune lettere.
-
-\begin{table}[h]

- \begin{tabular}{lccc}\toprule

- \end{tabular}
- \caption{Le lettere greche}\label{tab:upgreek_mode}
-\end{table}
-
-La ragione per cui \chemmacros definisce queste macro è per conformarsi alle regole
-\ac{iupac}: la \ac{iupac} consiglia di utilizzare lettere greche tonde nella nomenclatura.
-
-\begin{zitat}[{\ac{iupac} Green Book {\cite[][p.\,9]{iupac:greenbook}}}]
- Greek letters are used in systematic organic, inorganic, macromolecular and
- biochemical nomenclature. These should be roman (upright), since they are not
- symbols for physical quantities.
-\end{zitat}
-
-\chemmacros impiega questi comandi per definire comandi di nomenclatura (vedi a
-pagina~\pageref{par:greek_letters}).
-
-\subsection{Definire particelle proprie}\secidx[proprie]{Particelle, ioni e simboli}
-Talvolta può essere utile avere a disposizione delle ulteriori particelle come macro,
-come ad esempio \lstinline+\positron+ oppure \lstinline+\photon+. È possibile
-definirle agevolmente con i seguenti comandi:
-\begin{beschreibung}
- \Befehl{DeclareChemParticle}{<cmd>}\ma{<definition>}
- \Befehl{RenewChemParticle}{<cmd>}\ma{<definition>}
-\end{beschreibung}
-A seconda del \key{method} scelto come opzione, la \code{<definition>} viene svolta
-alternativamente con \paket{mhchem} o con \chemformula. La particella si comporta
-come quelle predefinite, tranne che per un'eccezione: la particella così definita
-obbedisce all'opzione \key{circled} solamente se è stato selezionato
-\key{method}{chemformula}. Se si desiderano cariche formali con \key{method}{mhchem},
-è necessario richiamare i comandi di \chemmacros in modo esplicito (vedi il
-paragrafo~\ref{sec:ladungen}).
-\begin{beispiel}
- % uses the `upgreek' package
- \DeclareChemParticle{\positron}{$\upbeta$+}
- \DeclareChemParticle{\photon}{$\upgamma$}
- \RenewChemParticle{\el}{$\upbeta$-}
- \positron\ \photon\ \el
-\end{beispiel}
-\cmd{DeclareChemParticle} definisce la particella solamente se \code{<cmd>} non
-esiste ancora. In caso diverso \chemmacros restituisce un avvertimento oppure un
-errore, dipendentemente dall'opzione \key{strict}. \cmd{RenewChemParticle} definisce
-una particella \emph{solamente} se \code{<cmd>} è \emph{già} esistente e restituisce
-un avvertimento o un errore in caso contrario.

-\section{Nomenclatura, stereodescrittori e termini in latino}\label{sec:stereo}
-\subsection{Nomi IUPAC}\secidx{Nomi IUPAC}
-Analogamente al pacchetto \paket{bpchem} anche \chemmacros mette a disposizione
-un comando\footnote{L'idea e la realizzazione provengono dal pacchetto \paket*{bpchem}
-di Bjørn Pedersen.} per inserire nomi \ac{iupac}. La sua utilità deriva da un
-motivo molto semplice: i nomi \ac{iupac} possono diventare particolarmente lunghi,
-così lunghi da riempire anche più di due righe, specialmente all'interno di documenti
-in due colonne. Ciò significa che devono poter essere divisi più di una volta. Per
-metterlo in pratica si può utilizzare il seguente comando:
-\begin{beschreibung}
- \befehl{iupac}{<IUPAC name>} All'interno di questo comando vengono impiegati
- {\catcode`\|=11\cmd{|}} e \cmd{-} per segnare punti di divisione oppure un
- trattino separatore. {\catcode`\^=11\cmd{^}} può essere utilizzato come
- abbreviazione per \lstinline=\textsuperscript=.
-\end{beschreibung}
-\begin{beispiel}
- \begin{minipage}{.4\linewidth}
- \iupac{Tetra\|ciclo[2.2.2.1\^{1,4}]\-un\|decano-2\-dodecil\-5\-(epta\|decil\|iso\|dodecil\|tio\|estere)}
- \end{minipage}
-\end{beispiel}
-Nonostante ciò, il comando \cmd{iupac} è più che altro un comando semantico. Nella
-maggior parte dei casi si può raggiungere un risultato (quasi) identico utilizzando
-\cmd{-} anziché {\catcode`\|=11\cmd{|}}, \code{-} anziché \cmd{-} e
-\lstinline=\textsuperscript= anziché {\catcode`\^=11\cmd{^}}.
-
-Vi sono delle sottili differenze: \cmd{-} inserisce un sottile spazio prima del
-trattino e rimuove un sottile spazio dopo. Il comando {\catcode`\|=11\cmd{|}} non
-evita solo le legature, bensì inserisce anche un sottile spazio.
-\begin{beispiel}
- \huge\iupac{2,4\-di\|cloro\|pentano} \\
- 2,4-dicloropentano
-\end{beispiel}
-
-Gli spazi inseriti possono essere adattati:
-\begin{beschreibung}
- \option[iupac]{hyphen-pre-space}{<dim>} default = \code{.01em}
- \option[iupac]{hyphen-post-space}{<dim>} default = \code{-.03em}
- \option[iupac]{break-space}{<dim>} default = \code{.01em}
-\end{beschreibung}
-
-Il comando \cmd{iupac} serve anche ad un altro scopo: indipendentemente dall'opzione
-globale \key[option]{iupac} tutti i comandi presentati in questo paragrafo sono
-sempre definiti \emph{internamente} a \cmd{iupac}. Tutta una serie di comandi di
-nomenclatura ha nomi molto generici come \cmd{meta}, \cmd{D}, \cmd{E}, \cmd{L},
-\cmd{R}, \cmd{S}, \cmd{trans} e così via; ne segue che spesso sono già predefiniti
-(\cmd{L} \L) oppure facilmente modificati da altri pacchetti o altre classi (ad
-esempio, il pacchetto \paket{cool} definisce sia \cmd{D} che \cmd{E}). Per potere
-controllare quali comandi siano definiti e come, esiste l'opzione globale
-\key[option]{iupac}\label{desc:iupac}, con tre modalità di utilizzo:
-\begin{itemize}
- \item \key{iupac}{auto}: se il comando \emph{non è definito} all'interno di un
- pacchetto o una classe in uso è disponibile generalmente, altrimenti solo
- \emph{all'interno} di \cmd{iupac}.
- \item \key{iupac}{restricted}: tutti i comandi di nomenclatura sono definiti
- \emph{solo internamente} a \cmd{iupac}. Sono disponibili esternamente solo se
- definiti da un'altro pacchetto.
- \item \key{iupac}{strict}: \chemmacros sovrascrive ogni definizione preesistente
- e rende disponibili i comandi \emph{in tutto il documento}. Possono essere ridefiniti
- (solo dopo \lstinline=\begin{document}=). Mantengono il significato di nomenclatura
- all'interno di \cmd{iupac}.
-\end{itemize}
-Nella tabella~\ref{tab:iupac_modes} è dimostrato il funzionamento delle diverse modalità.

-anche se personalmente consiglio di usare \cmd{ch} (vedi~ref{part:chemformula})
-e di dimenticare questi comandi.
-\begin{beschreibung}

- \ox[align=right]{2,Ca}
-\end{beispiel}
-
-La variante \key[ox]{pos}{super} può essere selezionata anche tramite
-l'abbreviazione \cmd[oxa]{ox*}:
-\begin{beispiel}
- \ox{3,Fe} \ox*{3,Fe}
-\end{beispiel}
-
-Impiegando \key[ox]{explicit-sign} viene sempre indicato il segno del numero di
-ossidazione:
-\begin{beispiel}
- \chemsetup[ox]{explicit-sign = true}
- \ox{+1,Na}, \ox{2,Ca}, \ox{-2,S}, \ch{"\ox{0,F}" {}2}
-\end{beispiel}
-
-\begin{beispiel}
- Si confronti ad esempio \ox{-1,\ch{O2^2-}} con \ch{"\ox{-1,O}" {}2^2-}
-\end{beispiel}
-
-Talvolta è necessario impiegare numeri d'ossidazione formali come \num{.5} oppure
-$\frac{1}{3}$:
-\begin{beispiel}
- \ox{.5,\ch{Br2}} \ch{"\ox{1/3,I}" {}3+}
-\end{beispiel}
-
-La frazione impiega il comando \lstinline+\sfrac+ del pacchetto \paket{xfrac}. A
-questo proposito è definita l'istanza \lstinline+chemmacros-ox-frac+.
-\begin{beispiel}[code only]
-\DeclareInstance{xfrac}{chemmacros-ox-frac}{text}
- {
- scale-factor = 1.2 ,
- denominator-bot-sep = -.5ex ,
- numerator-top-sep = -.3ex ,
- slash-left-kern = -.2em ,
- slash-right-kern = -.2em ,
- slash-symbol-font = lmr
- }
-\end{beispiel}
-Naturalmente può essere ridefinita a seconda dei propri gusti.

-\section{Reazioni redox}\label{sec:redoxreaktionen}\secidx{Reazioni redox}
-\chemmacros mette a disposizione due comandi con cui mostrare il trasferimento
-di elettroni nelle reazioni redox\footnote{Ringrazio~\href{http://www.mathannotated.com/}{Peter Cao},
-che ha proposto questa funzione.}. Entrambi i comandi utilizzano \TikZ.
-\begin{beschreibung}
- \Befehl{OX}{<name>,<atom>}
- \Befehl{redox}(<name1>,<name2>)[<tikz>]\oa{<num>}\ma{<text>} \cnpkgdocarrow\ È
- necessario solamente il primo argomento\\\da{<name1>,<name2>}; gli altri due
- sono opzionali.
-\end{beschreibung}
-
-\cmd{OX} pone \code{<atom>} in un nodo (un \enquote{node}) dal nome \code{<name>}.
-Una volta impiegati due \cmd{OX}, questi possono essere collegati tramite \cmd{redox};
-i nomi dei nodi da collegare vanno posti tra parentesi tonde. Dato che \cmd{redox}
-crea una Tikzpicture con le opzioni \code{remember picture,overlay}, il documento
-deve essere compilato \emph{almeno due volte}.
-\begin{beispiel}[dist]
- \OX{a,Na} $\rightarrow$ \OX{b,Na}\pch\redox(a,b){ossidazione}
-\end{beispiel}
-Questa linea può essere adattata con chiavi \TikZ entro \oa{<tikz>}:
-\begin{beispiel}[dist]
- \OX{a,Na} $\rightarrow$ \OX{b,Na}\pch\redox(a,b)[->,red]{ox}
-\end{beispiel}
-
-Con l'argomento \oa{<num>} si può adattare la lunghezza delle linee verticali.
-L'impostazione predefinita vale \code{.6em}, lunghezza che poi viene moltiplicata
-per \code{<num>}. Un valore negativo pone la linea \emph{sotto} il testo.
-\begin{beispiel}[dist]
- \OX{a,Na} $\rightarrow$ \OX{b,Na}\pch
- \redox(a,b)[->,red]{ox}
- \redox(a,b)[<-,blue][-1]{red}
- \vspace{7mm}
-\end{beispiel}
-
-Con la chiave
-\begin{beschreibung}
- \option[redox]{dist}{<dim>} Default = \code{.6em}
-\end{beschreibung}
-è possibile aggiustare il valore predefinito delle linee verticali:
-\begin{beispiel}[dist]
- \chemsetup{redox/dist=1em}
- \OX{a,Na} $\rightarrow$ \OX{b,Na}\pch\redox(a,b)[->,red]{ox}
-\end{beispiel}
-
-Inoltre l'opzione
-\begin{beschreibung}
- \option[redox]{sep}{<dim>} Default = \code{.2em}
-\end{beschreibung}
-permette di variare la distanza tra atomo e inizio della linea.
-\begin{beispiel}[dist]

-\section{Stati (standard), termodinamica}\label{sec:standardstate}\secidx{Termodinamica}
-\subsection{Grandezze termodinamiche}\label{ssec:siunitx}
-I comandi seguenti impiegano \paket{siunitx}:
-\begin{beschreibung}
- \Befehl{Enthalpy}[<options>]\da{<subscript>}\ma{<value>}
- \Befehl{Entropy}[<options>]\da{<subscript>}\ma{<value>}
- \Befehl{Gibbs}[<options>]\da{<subscript>}\ma{<value>}
-\end{beschreibung}
-
-Il loro utilizzo si spiega da sé:
-\begin{beispiel}
- \Enthalpy{123} \\
- \Entropy{123} \\
- \Gibbs{123}
-\end{beispiel}
-\da{<subscript>} aggiunge un pedice descrittivo: \cmd{Enthalpy}(r){123} \Enthalpy(r){123}.
-
-Questi comandi possono essere adattati tramite diverse opzioni:
-\begin{beschreibung}
- \Option*{exponent}{<anything>}
- \Option*{delta}{<anything>/false}
- \Option*{subscript}{left/right}
- \Option*{unit}{<unit>}
-\end{beschreibung}
-
-Il valore predefinito dipende dal relativo comando:
-\begin{beispiel}
- \Enthalpy[unit=\kilo\joule]{-285} \\
- \Gibbs[delta=false]{0} \\
- \Entropy[delta=\Delta,exponent=]{56.7}
-\end{beispiel}
-
-Numero e unità vengono composti secondo le regole di \paket{siunitx} e dipendono
-dalle sue impostazioni:
-\begin{beispiel}
- \Enthalpy{-1234.56e3} \\
- \sisetup{per-mode=symbol,exponent-product=\cdot,output-decimal-marker={,},group-four-digits=true}
- \Enthalpy{-1234.56e3}
-\end{beispiel}
-
-\subsubsection{Definire nuove grandezze}
-Con il comando
-\begin{beschreibung}
- \Befehl{DeclareChemState}[<options>]{<name>}\ma{<symbol>}\ma{<unit>}
-\end{beschreibung}
-è possibile definire nuove grandezze.
-\begin{beispiel}
- \DeclareChemState{Helmholtz}{A}{\kilo\joule\per\mole}
- \DeclareChemState[subscript-left=false,exponent=]{ElPot}{E}{\volt}
- \Helmholtz{123.4} \\
- \ElPot{-1.1} \\
- \ElPot[exponent=0]($\ch{Sn}|\ch{Sn^2+}||\ch{Pb^2+}|\ch{Pb}$){0.01}
-\end{beispiel}
-
-Le opzioni di questo comando sono quasi identiche a quelle delle grandezze stesse,
-con cui possono essere variate le impostazioni predefinite delle nuove grandezze.
-\begin{beschreibung}
- \Option*{exponent}{<anything>}
- \Option*{delta}{<anything>|false}
- \Option*{subscript-left}{\default{true}|false}
- \Option*{subscript}{<anything>}
-\end{beschreibung}
-
-\subsubsection{Ridefinire grandezze}
-Con
-\begin{beschreibung}
- \Befehl{RenewChemState}[<options>]{<name>}\ma{<symbol>}\ma{<unit>}
-\end{beschreibung}
-è possibile ridefinire grandezze preesistenti:
-
-\begin{beispiel}
- \RenewChemState{Enthalpy}{h}{\joule}
- \Enthalpy(f){12.5}
-\end{beispiel}
-Il comando è analogo a \cmd{DeclareChemState}, cioè ha le stesse opzioni.
-
-Sarebbe quindi facile -- seguendo le convenzioni termodinamiche -- definire una
-grandezza molare ed una assoluta:
-\begin{beispiel}
- \DeclareChemState[exponent=]{enthalpy}{h}{\kilo\joule\per\mole}% molar
- \RenewChemState[exponent=]{Enthalpy}{H}{\kilo\joule}% absolute
- \enthalpy{-12.3} \Enthalpy{-12.3}
-\end{beispiel}
-
-\subsection{Grandezze di stato}\label{ssec:state}
-I comandi presentati nel paragrafo~\ref{ssec:siunitx} internamente impiegano il
-comando\footnote{Nota bene: \ma{<subscript>} è un argomento \emph{opzionale}.}
-\begin{beschreibung}
- \Befehl{State}[<options>]{<symbol>}\ma{<subscript>}
-\end{beschreibung}
-Questo comando può essere utilizzato per scrivere le grandezze prive di valore e
-unità.
-
-Esempi:
-\begin{beispiel}
- \State{A}, \State{G}{f}, \State[subscript-left=false]{E}{\ch{Na}}, \State[exponent=\SI{1000}{\celsius}]{H}
-\end{beispiel}
-
-Le sue opzioni sono (quasi) identiche a quelle viste in precedenza:
-\begin{beschreibung}
- \Option[state]{exponent}{<anything>}
- \Option[state]{subscript-left}{true|false}
- \Option[state]{delta}{<anything>|false}

-\section{Spettroscopia e valori sperimentali}\label{sec:spektroskopie}\secidx{Spettroscopia}
-\subsection{Il comando \code{\textbackslash\textcolor{code}{NMR}}}
-Quando delle sostanze vengono analizzate per verificare se sono quello che si è
-previsto spesso si ricorre alla spettroscopia NMR. I valori sperimentali vengono
-riportati all'incirca in questo modo:
-\begin{center}
- \NMR(400)[CDCl3] = \num{1.59}
-\end{center}
-\chemmacros mette a disposizione un comando che semplifica questa stesura (impiega
-\paket{siunitx}).
-
-\begin{beschreibung}
- \Befehl{NMR}{<num>,<elem>}\da{<num>,<unit>}\oa{<solvent>}
- \Befehl{NMR*}{<num>,<elem>}\da{<num>,<unit>}\oa{<solvent>}
-\end{beschreibung}
-
-\emph{Tutti} gli argomenti sono opzionali! Senza argomenti\footnote{Tutti gli
-argomenti possono essere combinati a piacimento. Il comando può essere impiegato
-anche in modalità matematica.} si ottiene:
-\begin{beispiel}
- \NMR \\
- \NMR*
-\end{beispiel}
-
-Il primo argomento specifica il tipo di analisi NMR eseguito:
-\begin{beispiel}
- \NMR{13,C}
-\end{beispiel}
-
-Con il secondo argomento viene riportata la frequenza utilizzata (in \si{\mega\hertz}):
-\begin{beispiel}
- \NMR(400)
-\end{beispiel}
-Anche munita della sua unità:
-\begin{beispiel}
- \NMR(4e8,\hertz)
-\end{beispiel}
-Nota bene: le impostazioni del pacchetto \paket{siunitx} hanno effetto anche su
-questo comando:
-\begin{beispiel}
- \sisetup{exponent-product=\cdot}\NMR(4e8,\hertz)
-\end{beispiel}
-
-Con il terzo argomento può essere indicato il solvente:
-\begin{beispiel}
- \NMR[CDCl3]
-\end{beispiel}
-
-\subsection{Abbreviazioni}
-Dato che all'interno di un singolo documento alcuni nuclei possono essere richiamati
-più di una volta \chemmacros offre una possibilità di definire delle abbreviazioni.
-\begin{beschreibung}
- \Befehl{DeclareChemNMR}{<csname>}\ma{<num>,<atom>}
- \Befehl{RenewChemNMR}{<csname>}\ma{<num>,<atom>}
-\end{beschreibung}
-Questo definisce un comando con gli stessi argomenti di \cmd{NMR} \emph{eccetto}
-\ma{<num>,<atom>}.
-\begin{beispiel}
- \DeclareChemNMR\HNMR{1,H}%
- \DeclareChemNMR\CNMR{13,C}%
- \CNMR*(100) \\
- \HNMR*(400)
-\end{beispiel}
-
-\subsection{Un ambiente per elencare valori sperimentali}
-\chemmacros offre un ambiente dedicato per facilitare l'elenco di valori sperimentali.
-\begin{beschreibung}\catcode`\#=11
- \umg{experimental}{Dati} Ambiente per l'elenco di dati sperimentali. All'interno
- di questo ambiente sono definiti i comandi seguenti:
- \Befehl{data}{<tipo>}\oa{<specifiche>} \cnpkgdocarrow\ Tipo dei dati, \pes IR,
- MS\ldots\ Nell'argomento opzionale possono essere inserite specifiche ulteriori
- che vengono stampate in parentesi tonde.
- \Befehl{data*}{<tipo>}\oa{<specifiche>} \cnpkgdocarrow\ Come \cmd{data}, ma
- restituisce \code{=} anziché \code{:} se vale \key{use-equal}{true}.
- \Befehl{NMR}{<num>,<elem>\oa{<coupling core>}}\da{<num>,<unit>}\oa{<solvent>}
- \cnpkgdocarrow\ questo comando prende un argomento aggiuntivo:
- \cmd{NMR}{13,C[\textasciicircum 1H]} \NMR{13,C[^1H]}
- \Befehl{J}\da{<bonds>;<nuclei>}\oa{<unit>}\ma{<list of nums>} \cnpkgdocarrow\
- Costante di accoppiamento (NMR) con il separatore \code{;} tra i valori.
- L'argomento \da{<bonds>;<nuclei>} è opzionale e permette di specificare
- ulteriormente l'accoppiamento.
- \befehl{#}{<num>} Numero di nuclei (NMR).
- \befehl{pos}{<num>} Posizione/numero del nucleo (NMR).
- \befehl{val}{<num>} Valore numerico, un alias per \lstinline+\num{<num>}+ di
- \paket*{siunitx}.
- \befehl{val}{<num1>-{}-<num2>} Un alias per \lstinline+\numrange{<num1>}{<num2>}+
- di \paket*{siunitx}.
-\end{beschreibung}
-
-\begin{beispiel}
- \begin{experimental}
- \data{TIPO1} dati.
- \data{TIPO2}[specifiche] altri dati.
- \data*{TIPO3} ulteriori dati.
- \end{experimental}
-\end{beispiel}
-
-\subsection{Personalizzazione}
-L'output dell'ambiente e dei comandi NMR può essere adattato con una serie di
-opzioni; per ragioni storiche appartengono al modulo \textcolor{module}{\code{nmr}}.
-\begin{beschreibung}
- \option[nmr]{unit}{<unit>} Default = \lstinline=\mega\hertz=
- \option[nmr]{nucleus}{\{<num>,<atom>\}} Default = \ma{1,H}
- \option[nmr]{format}{<commands>} Formato delle specifiche dei dati, ad esempio
- \lstinline=\bfseries=.
- \option[nmr]{pos-number}{side|sub} Posizione del numero vicino all'atomo.
- Default = \code{side}
- \option[nmr]{coupling-unit}{<unit>} Un'unità di \paket{siunitx}. Default =
- \lstinline=\hertz=
- \option[nmr]{parse}{\default{true}|false} Tratta il solvente come formula di
- \paket{mhchem}/\chemformula. Default = \code{true}
- \option[nmr]{delta}{<token>} I \code{<token>} vengono inseriti dopo $\delta$.
- \option[nmr]{list}{true|false} L'ambiente \env{nmr}[<options>]{} viene formattato
- come lista. Default = \code{false}
- \option[nmr]{list-setup}{<setup>} Setup della lista. Default = vedi in basso.
- \option[nmr]{use-equal}{\default{true}|false} Inserisce un segno di uguale dopo
- \cmd{NMR} e \cmd{data}. Default = \code{false}
-\end{beschreibung}
-
-Il setup di default della lista:
-\begin{beispiel}[code only]
- \topsep\z@skip \partopsep\z@skip
- \itemsep\z@ \parsep\z@ \itemindent\z@
- \leftmargin\z@
-\end{beispiel}
-
-\begin{beispiel}
- \begin{experimental}[format=\bfseries]
- \data{TIPO1} dati.
- \data{TIPO2}[specifiche] altri dati.
- \data*{TIPO3} ulteriori dati.
- \end{experimental}
-\end{beispiel}
-
-Il comando \cmd{NMR} e tutti i comandi definiti con \cmd{DeclareChemNMR} possono
-essere impiegati al posto di \cmd{data} per dati NMR.
-
-\begin{beispiel}
- \begin{experimental}[format=\bfseries,use-equal]
- \data{TIPO1} dati.
- \data{TIPO2}[specifiche] altri dati.
- \NMR ulteriori dati.
- \end{experimental}
-\end{beispiel}

-\section{Comandi per \textsf{mhchem}}\label{sec:mhchem}\secidx{Comandi per \textsf{mhchem}}[Comandi per mhchem]
-\paket{mhchem} non viene più caricato automaticamente da \chemmacros bensì solamente
-nel caso in cui si utilizzi nel preambolo l'opzione \key[option]{method}{mhchem};
-predefinitamente si utilizza invece \chemformula.
-
-\chemmacros mette a disposizione solo un unico comando speciale per \paket{mhchem}%
-\footnote{\chemformula ha una possibilità diversa per ottenere lo stesso risultato.}
-che permette di inserire del testo al di sotto di una formula.
-\begin{beschreibung}
- \Befehl{mhName}[<options>]{<formula>}\ma{<text>}
-\end{beschreibung}
-
-Per esempio:
-\begin{beispiel}
- \ce{4 C2H5Cl + Pb / Na -> \mhName{Pb(C2H5)4}{former antiknock additive} + NaCl}
-\end{beispiel}
-
-\cmd{mhName} può essere adattato con le opzioni seguenti:
-\begin{beschreibung}
- \option[mhName]{align}{<alignment command>} L'orientamento del testo all'interno
- del box in cui viene scritto. Default = \lstinline+\centering+
- \option[mhName]{format}{<anything>} Il formato del testo.
- \option[mhName]{fontsize}{<font size command>} Il corpo del testo. Default =
- \lstinline+\tiny+
- \option[mhName]{width}{<dim>|auto} La larghezza del box all'interno di cui viene
- scritto il testo. Default = \code{auto}

-\section{Ambienti di reazione}\label{sec:reactions}\secidx{Ambienti di reazione}
-\subsection{Definiti da \chemmacros}
-Sono disponibili i seguenti ambienti per reazioni numerate\ldots
-\begin{beschreibung}
- \Umg{reaction}{<formula or mhchem code>}
- \Umg{reactions}{<formula or mhchem code>}
-\end{beschreibung}
-
-\ldots e le loro versioni asteriscate per reazioni non numerate.
-\begin{beschreibung}
- \Umg{reaction*}{<formula or mhchem code>}
- \Umg{reactions*}{<formula or mhchem code>}
-\end{beschreibung}
-In questo modo è possibile inserire reazioni (non) numerate in modo analogo alle
-equazioni matematiche.
-
-Per rappresentare le reazioni gli ambienti \code{reaction}/\code{reaction*} internamente
-utilizzano ambienti \code{equation}/\code{equation*}, e gli ambienti
-\code{reactions}/\code{reactions*} utilizzano gli ambienti \code{align}/\code{align*}.
-
-\begin{beispiel}
- reazione con contatore:
- \begin{reaction}
- A -> B
- \end{reaction}
-\end{beispiel}
-
-\begin{beispiel}
- reazione senza contatore:
- \begin{reaction*}
- C -> D
- \end{reaction*}
-\end{beispiel}
-
-\begin{beispiel}
- più reazioni allineate, con contatore:
- \begin{reactions}
- A &-> B + C \\
- D + E &-> F
- \end{reactions}
-\end{beispiel}
-
-\begin{beispiel}
- più reazioni allineate, senza contatore:
- \begin{reactions*}
- G &-> H + I \\
- J + K &-> L
- \end{reactions*}
-\end{beispiel}
-
-Quando si desidera cambiare il formato dell'etichetta, è possibile usare
-\begin{beschreibung}
- \Befehl{renewtagform}{<tagname>}\oa{<format>}\ma{<right delim>}\ma{<left delim>}%
- \footnote{Messo a disposizione dal pacchetto \paket*{mathtools}.}.
-\end{beschreibung}
-
-\begin{beispiel}
- \renewtagform{reaction}[R \textbf]{[}{]}
- \begin{reaction}
- H2O + CO2 <<=> H2CO3
- \end{reaction}
-\end{beispiel}
-
-Dalla versione 3.3 i riferimenti incrociati e il comando \cmd{intertext} di \AmS math
-funzionano come previsto:
-\begin{beispiel}
- \begin{reactions}
- A + 2 B &-> 3 C + D \label{rxn:test}
- \intertext{Un po' di testo tra due reazioni allineate.}
- 3 E + F &<=> G + 1/2 H
- \end{reactions}
- Vedi reazione~\ref{rxn:test}.
-\end{beispiel}
-
-\achtung{Nell'impostazione predefinita, cioè con \key{method}{chemformula}, è
-sconsigliato utilizzare \cmd{mch} e simili all'interno degli ambienti
-\code{reaction}: nella maggior parte dei casi scombinano l'allineamento corretto.
-Come impostazione predefinita le cariche riconoscono automaticamente l'impostazione
-dell'opzione \key{circled} all'interno degli ambienti, in modo che i comandi non
-siano nemmeno necessari.}
-
-\subsection{Reazioni proprie}
-Attraverso il comando
-\begin{beschreibung}
- \Befehl{DeclareChemReaction}[<options>]{<name>}\ma{<math name>}
-\end{beschreibung}
-è possibile definire nuovi ambienti di reazione: \code{<name>} sarà il nome del
-nuovo ambiente; \code{<math name>} è il tipo di ambiente matematico impiegato.
-
-Il comando ha due opzioni:
-\begin{beschreibung}
- \Option*{star}{\default{true}|false}
- \Option*{arg}{\default{true}|false}
-\end{beschreibung}
-La prima opzione è \key*{star}, che definisce anche la variante asteriscata,
-ammesso che esista l'equivalente ambiente matematico; in caso contrario restituirà
-un errore.
-
-La seconda opzione è \key*{arg}, che viene impiegata per definire un ambiente con
-un argomento obbligatorio. Anche in questo caso l'opzione è valida solamente se
-anche l'ambiente matematico corrispondente ha un argomento obbligatorio.
-
-Gli ambienti predefiniti sono stati definiti tramite
-\begin{beschreibung}
- \Befehl{DeclareChemReaction}[star]{reaction}\ma{equation} und
- \Befehl{DeclareChemReaction}[star]{reactions}\ma{align}.
-\end{beschreibung}
-
-Ammettiamo che l'utente voglia definire un ambiente con il comportamento dell'ambiente
-\code{alignat} per reazioni di \chemformula/\paket{mhchem}. È possibile fare il
-seguente:
-\begin{beispiel}[code only]
- \DeclareChemReaction[star,arg]{reactionsat}{alignat}
-\end{beispiel}
-
-In questo modo si è definito l'ambiente \code{reactionsat}.
-\begin{beispiel}
- \DeclareChemReaction[star,arg]{reactionsat}{alignat}
- \begin{reactionsat}{3}
- A &-> B &&-> C &&-> D \\
- aaaaa &-> bbbbb &&-> ccccc &&-> ddddd
- \end{reactionsat}
- \begin{reactionsat*}{2}
- A &-> B & C &-> D \\
- aaaaa &-> bbbbb &\quad{} ccccc &-> ddddd
- \end{reactionsat*}
-\end{beispiel}
-
-\subsection{Lista delle reazioni}
-\chemmacros mette a disposizione un comando per elencare le reazioni inserite negli
-ambienti di reazione.
-\begin{beschreibung}
- \Befehl{listofreactions}
-\end{beschreibung}
-\begin{beispiel}[below]
- \listofreactions
-\end{beispiel}
-
-L'output può essere adattato con le opzioni seguenti:
-\begin{beschreibung}
- \option[reaction]{list-name}{<name of the list>} Imposta il titolo della lista.
- Default = \code{List of reactions}
- \option[reaction]{list-entry}{<prefix to each entry>} Prefisso di ogni voce.
- Default = \code{Reaction}
-\end{beschreibung}
-Entrambi i valori predefiniti reagiscono all'opzione di lingua \key[option]{italian},
-variando rispettivamente a \enquote{Elenco delle reazioni} e \enquote{Reazione}.
-Un'alternativa all'impostazione dell'opzione \key{list-name} è di ridefinire
-\cmd{reactionlistname}.
-
-Nell'elenco vengono elencate esclusivamente tutte le reazioni numerate. Tutte le
-reazioni non asteriscate hanno un argomento opzionale, attraverso il quale è
-possibile aggiungere una descrizione della reazione nell'elenco.
-\begin{beispiel}
- \begin{reaction}[Autoprotolisi]
- 2 H2O <<=> H3O+ + OH-
- \end{reaction}
-\end{beispiel}
-Questo non funzionerà quando viene impiegato l'ambiente \code{reactions}. In
-questo caso è possibile ricorrere a
-\begin{beschreibung}
- \Befehl{AddRxnDesc}{<description>}
-\end{beschreibung}
-
-\begin{beispiel}
- \begin{reactions}
- Cl "\Lewis{0.,\vphantom{Cl}}" + CH4 &-> HCl + "\Lewis{4.,\vphantom{CH}}" CH3 \AddRxnDesc{first~step~of~chain} \\
- "\Lewis{4.,\vphantom{CH}}" CH3 + Cl2 &-> CH3Cl + Cl "\Lewis{0.,\vphantom{Cl}}" \AddRxnDesc{second~step~of~chain}
- \end{reactions}
-\end{beispiel}
-Nota bene: non è necessario impiegare i comandi \enquote{phantom}, se il formato
-degli atomi non è stato variato (vedi il paragrafo~\ref{sec:format} a pagina~\pageref{sec:format}).

-\section{Fasi}\label{sec:phasen}\secidx{Fasi}
-\subsection{Principi}\secidx[Principi]{Fasi}
-Questi comandi sono pensati per indicare la fase di una sostanza.
-\begin{beschreibung}
- \befehl{sld} \sld
- \befehl{lqd} \lqd
- \befehl{gas} \gas
- \befehl{aq} \aq
-\end{beschreibung}
-
-\achtung{Il comportamento predefinito dei comandi di fase è variato per seguire
-le raccomandazioni \ac{iupac}. Sia \cmd{sld} che \cmd{lqd} non hanno più nessun
-argomento opzionale.}
-
-\begin{beispiel}
- \ch{C\sld{} + 2 H2O\lqd{} -> CO2\gas{} + 2 H2\gas}\\
- per completezza: NaCl\aq.
-\end{beispiel}
-
-% Con l'opzione \key{language}{german} (vedi il paragrafo~\ref{sec:optionen}) si ottengono le versioni in tedesco. % IST SCHON ÜBERSETZT, WÜRDE ICH ABER VORERST WEGLASSEN. -Jonas
-
-La raccomandazione \ac{iupac}\footnote{Ringrazio Paul King del suggerimento.} per
-indicare uno stato di aggregazione è di porlo tra parentesi dopo la formula~\cite{iupac:greenbook};
-è tuttavia molto diffusa anche l'indicazione in pedice.
-
-\begin{zitat}[{\ac{iupac} Green Book {\cite[][p.\,54]{iupac:greenbook}}}]
- The \textelp{} symbols are used to represent the states of aggregation of chemica
- species. The letters are appended to the formula in parentheses and should be
- printed in Roman (upright) type without a full stop (period).
-\end{zitat}
-
-Vi sono due opzioni per adattare l'output:
-\begin{beschreibung}
- \option[phases]{pos}{side|sub} Cambia la posizione dell'indicatore di fase.
- Default = \code{side}
- \option[phases]{space}{<dim>} Varia l'interspazio tra formula e indicatore di fase
- per \key{pos}{side}. Una grandezza di \TeX. Default = \code{.1333em}
-\end{beschreibung}
-\begin{beispiel}
- \chemsetup[phases]{pos=sub}
- \ch{C\sld{} + 2 H2O\lqd{} -> CO2\gas{} + 2 H2\gas}\\
- per completezza: NaCl\aq.
-\end{beispiel}
-
-\subsection{Definire fasi proprie}\secidx[proprie]{Fasi}
-In base al argomento del testo può essere necessario indicare ulteriori stati di
-aggregazione; questi possono essere definiti convenientemente attraverso:
-\begin{beschreibung}
- \Befehl{DeclareChemPhase}{<cmd>}\oa{<german>}\ma{<english>}
- \Befehl{RenewChemPhase}{<cmd>}\oa{<german>}\ma{<english>}
- \befehl{phase}{<phase>} Quando è necessario impiegare la fase solo poche volte.
-\end{beschreibung}
-\cmd{DeclareChemPhase} definisce la fase solamente se \code{<cmd>} non esiste ancora;
-altrimenti \chemmacros dà un avvertimento o un errore, dipendentemente dall'opzione
-\key{strict}. \cmd{RenewChemParticle} definisce una fase \emph{solamente} se \code{<cmd>}
-esiste già, e dà un avvertimento/un errore in caso opposto.
-\begin{beispiel}
- \DeclareChemPhase{\aqi}{aq,$\infty$}% aqueous solution at infinite dilution
- \DeclareChemPhase{\cd}{cd}% condensed phase
- \RenewChemPhase{\lqd}{lc}% liquid crystal
- NaOH\aqi\ \ch{H2O\cd} U\phase{cr} A\lqd \\

-\begin{beschreibung}
- \Befehl{newman}[<options>]\da{<angle>}\ma{<1>,<2>,<3>,<4>,<5>,<6>}
-\end{beschreibung}
-che permette di rappresentare le proiezioni di Newman (impiega \TikZ). L'argomento
-\da{<angle>} gira gli atomi posteriori in senso antiorario rispetto agli atomi
-anteriori.
-\begin{beispiel}
- \newman{} \newman(170){}
- \newman{1,2,3,4,5,6} \newman{1,2,3} \newman{,,,4,5,6}
-\end{beispiel}
-
-Sono disponibili alcune opzioni per adattare il comando:
-\begin{beschreibung}
- \option[newman]{angle}{<angle>} Angolo predefinito (in gradi). Default = \code{0}
- \option[newman]{scale}{<factor>} Scala l'intera proiezione. Default = \code{1}
- \option[newman]{ring}{<tikz>} Adatta l'aspetto dell'anello con chiavi di \TikZ.
- \option[newman]{atoms}{<tikz>} Adatta l'aspetto dei nodi contenenti gli atomi con
- chiavi di \TikZ.
- \option[newman]{back-atoms}{<tikz>} Adatta solo gli atomi posteriori.

-\section{Orbitali s, p e ibridi}\label{sec:orbitale}\secidx{Orbitali}
-\chemmacros mette a disposizione un comando per rappresentare alcuni orbitali:
-\begin{beschreibung}
- \Befehl{orbital}[<options>]{<type}
-\end{beschreibung}
-
-Sono disponibili i seguenti tipi orbitalici per \ma{<type>}:
-\begin{description}
- \item \code{s}
- \item \code{p}
- \item \code{sp}
- \item \code{sp2}
- \item \code{sp3}
-\end{description}
-
-\begin{beispiel}
- \orbital{s} \orbital{p} \orbital{sp} \orbital{sp2} \orbital{sp3}
-\end{beispiel}
-
-A seconda del tipo sono disponibili diverse opzioni per modificare l'orbitale:
-\begin{beschreibung}
- \option[orbital]{phase}{\default{+}|-} Varia la fase dell'orbitale (tutti i tipi).
- \option[orbital]{scale}{<factor>} Varia la dimensione dell'orbitale (tutti i tipi).
- \option[orbital]{color}{<color>} Varia il colore dell'orbitale (tutti i tipi).
- \option[orbital]{angle}{<angle>} Ruota gli orbitali con un contributo p in senso
- antiorario (tutti i tipi tranne \code{s}).
- \option[orbital]{half}{\default{true}|false} Raffigura solo metà orbitale (solo per
- \code{<type> = p}).
-\end{beschreibung}
-
-\begin{beispiel}
- \orbital{s} \orbital[phase=-]{s}
- \orbital{p} \orbital[phase=-]{p}
- \orbital{sp3} \orbital[phase=-]{sp3}
-
- \orbital[angle=0]{p} \orbital[color=red!50]{p} \orbital[angle=135,scale=1.5]{p} \orbital[half]{p}
-\end{beispiel}
-
-Esistono due opzioni ulteriori attraverso le quali si può influenzare il comportamento
-di \TikZ:
-\begin{beschreibung}
- \option[orbital]{overlay}{\default{true}|false} L'orbitale \enquote{non ha bisogno
- di spazio}; viene disegnato con la chiave di \TikZ \code{overlay}.
- \option[orbital]{opacity}{<num>} L'orbitale diviene trasparente; \code{<value>}
- accetta valori compresi tra \code{1} (opaco) e \code{0} (trasparente).
-\end{beschreibung}

-\section{Impostazioni}
-Tutte le opzioni di \chemformula appartengono al modulo \textcolor{module}{\code{chemformula}}. Quindi possono essere impostate attraverso
-\begin{beispiel}[code only]
- \chemsetup[chemformula]{<options>} oppure
- \chemsetup{chemformula/<option1>,chemformula/<option2>}
-\end{beispiel}
-Possono inoltre essere passate direttamente come opzioni al comando \cmd{ch}.
-
-\section{Principio di base}
-\chemformula ha un comando di base.
-\begin{beschreibung}
- \Befehl{ch}[<options>]{<input>}
-\end{beschreibung}
-
-Il suo utilizzo sarà intuitivo per l'utente pratico di \paket{mhchem}:
-\begin{beispiel}
- \ch{H2O} \\
- \ch{Sb2O3} \\
- \ch{H+} \\
- \ch{CrO4^2-} \\
- \ch{AgCl2-} \\
- \ch{[AgCl2]-} \\
- \ch{Y^{99}+} \\
- \ch{Y^{99+}} \\
- \ch{H2_{(aq)}} \\
- \ch{NO3-} \\
- \ch{(NH4)2S} \\
- \ch{^{227}_{90}Th+} \\
- $V_{\ch{H2O}}$ \\
- \ch{Ce^{IV}} \\
- \ch{KCr(SO4)2 * 12 H2O}
-\end{beispiel}
-
-Tuttavia esistono delle differenze. La più importante è: \chemformula distingue
-diversi tipi di input. Questi tipi diversi devono essere \emph{necessariamente}
-separati da spazi:
-\begin{beschreibung}
- \Befehl{ch}{type1 type2 type3 type4}
-\end{beschreibung}
-Uno spazio nell'input non corrisponde \emph{mai} ad uno spazio nell'output. Il
-ruolo dello spazio vale strettamente, e quando non viene seguito può produrre output
-erratico. A titolo di esempio, \cmd{ch}{2H2O} viene considerata come \emph{una}
-particella, in questo caso una formula bruta.
-\begin{beispiel}
- \ch{2H2O} \\
- \ch{2 H2O}
-\end{beispiel}
-Ciò significa anche che una particella non può contenere spazi perché verrebbe
-automaticamente divisa in due parti. Quando necessario, uno spazio può essere
-introdotto con \lstinline+~+. Dato che la maggior parte delle macro ignora gli
-spazi seguenti, un input del tipo \cmd{ch}{\textbackslash command ABC} viene
-trattato come un'unità. Nel caso si desideri separare un input di questo tipo
-è necessario introdurre un gruppo vuoto: \cmd{ch}{\textbackslash command\{\} ABC}.
-I diversi tipi di input verranno trattati separatamente in seguito.
-
-Un'ulteriore differenza importante è che \chemformula cerca di evitare il modo
-matematico quanto più possibile:
-\begin{beispiel}
- \ch{A + B ->[a] C} \\
- \ce{A + B ->[a] C}
-\end{beispiel}
-
-Il comando \cmd{ch} ha alcune opzioni per modificare l'output. Possono essere
-impostate localmente come argomenti opzionali oppure globalmente con il comando
-\begin{beschreibung}
- \Befehl{chemsetup}[chemformula]{<options>}
-\end{beschreibung}
-Tutte le opzioni di \chemformula appartengono al modulo \textcolor{module}{\code{chemformula}}.
-
-\section{Fattori stechiometrici}\secidx{Fattori stechiometrici}
-Un fattore stechiometrico deve contenere solo cifre e simboli tra i seguenti: \lstinline+.,_/()+
-\begin{beispiel}
- \ch{2} \\
- \ch{12}
-
- % decimals:
- \ch{.5} \\
- \ch{5,75}
-
- % fractions:
- \ch{3/2} \\
- \ch{1_1/2}
-
- % ``iupac'':
- \ch{(1/2)}
-\end{beispiel}
-
-Come nell'esempio per le frazioni decimali viene introdotto uno zero iniziale
-quando manca nell'input.
-
-Nell'input è necessario badare alla sintassi giusta, anche se ritengo che sia
-piuttosto intuitiva.
-\begin{beispiel}[code only]
- questo non funzionerà, ma darà invece un errore: \ch{1/1_1}
-\end{beispiel}
-
-Quando i fattori stechiometrici sono scritti tra parentesi le frazioni non vengono
-convertite e gli eventuali zeri iniziali non vengono aggiunti.
-Il testo inserito tra parentesi viene reso allo stesso modo dell'input.
-\begin{beispiel}
- \ch{(1/2) H2O} \ch{1/2 H2O} \ch{0.5 H2O}
-\end{beispiel}
-Numerosi esempi come il seguente per l'utilizzo delle parentesi per racchiudere
-fattori stechiometrici possono essere trovati per esempio nello „\ac{iupac} Green
-Book“~\cite{iupac:greenbook}:
-\begin{reaction*}
- (1/5) K "\ox*{7,Mn}" O4 + (8/5) HCl == (1/5) "\ox*{2,Mn}" Cl2 + (1/2) Cl2 + (1/5) KCl + (4/5) H2O
-\end{reaction*}
-
-L'output può essere adattato utilizzando le opzioni seguenti:
-\begin{beschreibung}
- \option{decimal-marker}{<marker>} Il simbolo usato come separatore decimale.
- Default = \code{.}
- \option{frac-style}{math|xfrac|nicefrac} Determina in che modo vengono rappresentate
- le frazioni. Default = \code{math}
- \option{stoich-space}{<skip>} La dimensione dello spazio dopo un fattore stechiometrico.
- Una lunghezza elastica. Default = \code{.1667em plus .0333em minus .0117em}
- \option{stoich-paren-parse}{\default{true}|false} Quando l'opzione è impostata
- a \code{true} anche i fattori stechiometrici compresi tra parentesi vengono
- elaborati, cioè le frazioni convertite e gli zeri iniziali inseriti.
- Default = \code{false}
-\end{beschreibung}
-\begin{beispiel}
- \ch[decimal-marker={,}]{3.5} \ch[decimal-marker={$\cdot$}]{3,5}
-\end{beispiel}
-
-L'opzione \key{frac-style}{xfrac} utilizza il comando \lstinline+\sfrac+ del
-pacchetto \paket{xfrac}; l'output può dipendere fortemente dal carattere impiegato.
-\secidx[xfrac]{Fattori stechiometrici}
-\begin{beispiel}
- \ch[frac-style=xfrac]{3/2} \ch[frac-style=xfrac]{1_1/2}
-\end{beispiel}
-
-\chemformula definisce l'istanza \lstinline=formula-text-frac=, che può essere
-adattata alle proprie necessità. Le impostazioni di default sono elencate di seguito:
-\begin{beispiel}[code only]
- \DeclareInstance{xfrac}{chemformula-text-frac}{text}
- {
- slash-left-kern = -.15em ,
- slash-right-kern = -.15em
- }
-\end{beispiel}
-Questo documento impiega il Font Linux Libertine~O e la definizione seguente:
-\begin{beispiel}[code only]
- \DeclareInstance{xfrac}{chemformula-text-frac}{text}
- {
- scale-factor = 1 ,
- denominator-bot-sep = -.2ex ,
- denominator-format = \scriptsize #1 ,
- numerator-top-sep = -.2ex ,
- numerator-format = \scriptsize #1 ,
- slash-right-kern = .05em ,
- slash-left-kern = .05em
- }
-\end{beispiel}
-
-L'opzione \key{frac-style}{nicefrac} utilizza il comando \lstinline+\nicefrac+ del
-pacchetto \paket{nicefrac}.\secidx[nicefrac]{Fattori stechiometrici}
-\begin{beispiel}
- \ch[frac-style=nicefrac]{3/2} \ch[frac-style=nicefrac]{1_1/2}
-\end{beispiel}
-
-L'opzione \key{stoich-space} permette di adattare la larghezza dello spazio tra
-fattore stechiometrico e formula bruta.\secidx[space]{Fattori stechiometrici}
-\begin{beispiel}
- \ch{2 H2O} \\
- \ch[stoich-space=.3em]{2 H2O}
-\end{beispiel}
-\secidx*{Fattori stechiometrici}
-
-\section{Formule brute}\label{ssec:compounds}\secidx{Formule brute}
-\chemformula considera le formule brute come il tipo \enquote{diverso da tutti gli
-altri}. Questo diverrà più chiaro in seguito quando saranno elencati gli altri tipi.
-\begin{beispiel}
- \ch{H2SO4} \\
- \ch{[Cu(NH3)4]^2+}
-\end{beispiel}
-
-\subsection{Addotti}\secidx[Addotti]{Formule brute}
-\chemformula riconosce due identificatori che creano addotti.
-\begin{beschreibung}
- \befehl{ch}{A.B} \ch{A.B}
- \befehl{ch}{A*B} \ch{A*B}
-\end{beschreibung}
-\begin{beispiel}
- \ch{CaSO4.H2O} \\
- \ch{CaSO4*H2O}
-\end{beispiel}
-Dato che le cifre all'interno di una formula bruta vengono considerate sempre
-come pedici (vedi il paragrafo~\ref{ssec:subscripts}), talvolta è necessario
-lasciare uno spazio in modo che il numero venga riconosciuto come fattore
-stechiometrico:
-\begin{beispiel}
- \ch{Na3PO4*12H2O} \\
- \ch{Na3PO4* 12 H2O} \\
- \ch{Na3PO4 * 12 H2O}
-\end{beispiel}
-
-\subsection{Pedici}\label{ssec:subscripts}\secidx[Pedici]{Formle brute}
-\emph{Tutte} le cifre in una sostanza vengono considerate come pedici.
-\begin{beispiel}
- \ch{H2SO4}
-\end{beispiel}
-Quando si desidera utilizzare un carattere come pedice, va utilizzata la sintassi
-matematica:
-\begin{beispiel}
- \ch{A_nB_m}
-\end{beispiel}
-
-Il pedice riconosce i gruppi, all'interno dei quali è anche possibile usare il modo
-matematico.
-\begin{beispiel}
- \ch{A_{$n$}B_{$m$}} \\
- \ch{NaCl_{(aq)}}
-\end{beispiel}
-
-\subsection{Comandi}\secidx[Comandi]{Formule brute}
-All'interno di una formula bruta sono permessi i comandi:
-\begin{beispiel}
- \ch{\textbf{A2}B3} \ch{A2\color{red}B3}
-\end{beispiel}
-Quando però un comando richiede come argomento un numero, ad esempio comandi
-regolanti la spaziatura oppure il comando \lstinline+\ox+, l'utilizzo diretto
-fallirà. Questo deriva dal fatto che le cifre verranno riconosciute come pedice
-\emph{prima} dell'espansione del comando.
-\begin{beispiel}[code only]
- \ch{A\hspace{2mm}B} darà un errore, dato che \hspace vedrà qualcosa del genere: \hspace{$_2$mm}.
-\end{beispiel}
-Vedi il paragrafo~\ref{ssec:text} per una via d'uscita da questo problema.
-
-\subsection{Cariche ed altri apici}\secidx[Cariche]{Formule brute}\secidx[Apici]{Formule brute}
-\paragraph{Principi}
-Quando una formula bruta \emph{termina} con un segno più o meno, questo verrà
-interpretato come un simbolo di carica e messo ad apice. In altri punti un più
-rappresenta un legame triplo ed un trattino un legame singolo, vedi il
-paragrafo~\ref{ssec:bonds}.
-\begin{beispiel}
- \ch{A+B} \ch{AB+} \\
- \ch{A-B} \ch{AB-}
-\end{beispiel}
-
-Per gruppi di carica più lunghi oppure altri apici è possibile utilizzare la sintassi
-matematica, che riconosce i gruppi e permette il modo matematico al loro interno.
-Entro questi gruppi né il simbolo \code{+} né \code{-} vengono interpretati come
-legami. Quando ad apice si trova un punto \code{.} non indica un addotto bensì un
-radicale. Un asterisco \code{*} indica uno stato eccitato.
-\begin{beispiel}
- \ch{A^{x-}} \\
- \ch{A^x-} \\
- \ch{A^{x}-} \\
- \ch{A^{$x-$}} \\
- \ch{RNO2^{-.}} \\
- \ch{^31H} \\
- \ch{^{14}6C} \\
- \ch{^{58}_{26}Fe} \\
- \ch{NO^*}
-\end{beispiel}
-
-Ioni e composti ionici con più di una carica vengono inseriti in modo analogo:
-\begin{beispiel}
- \ch{SO4^2-} \ch{Ca^2+ SO4^2-}
-\end{beispiel}
-
-\paragraph{Comandi ionici}\secidx[Apici!Comandi di carica]{Formule brute}
-All'interno di \cmd{ch} non sono necessari comandi del tipo di \cmd{mch}; difatti
-\emph{è opportuno evitarli}, dato che possono scombinare l'orientamento degli apici
-e dei pedici. L'opzione \code{circled} di \chemmacros viene rispettata da \cmd{ch}.
-\begin{beispiel}
- \chemsetup[option]{circled=all}
- \ch{H+ + OH- <=> H2O}
-\end{beispiel}
-
-\paragraph{Comportamento}\secidx[Apici!Comportamento]{Formule brute}
-Nel caso apice e pedice siano direttamente consecutivi in una formula bruta gli
-apici si comportano diversamente in base alla loro posizione.
-\begin{beispiel}
- \ch{^33B} \ch{{}^33B} \ch{3^3B} \ch{B^3} \ch{B3^3} \\
- \ch{^{23}_{123}B} \ch{{}^{23}_{123}B} \ch{_{123}^{23}B} \ch{B^{23}} \ch{B_{123}^{23}} \\
- \ch{^{123}_{23}B} \ch{{}^{123}_{23}B} \ch{_{23}^{123}B} \ch{B^{123}} \ch{B23^{123}}
-\end{beispiel}
-\begin{itemize}
- \item Quando una formula \emph{inizia} con un apice, gli apici e i pedici vengono
- giustificati a \emph{destra}, altrimenti a \emph{sinistra}.
- \item Quando un apice \emph{segue} un pedice, questo verrà ulteriormente spostato
- di una lunghezza che viene determinata dall'opzione \key{charge-hshift}{<dim>}
- (vedi anche a pagina~\pageref{desc:charge-hshift}s).
-\end{itemize}
-
-Il secondo punto segue l'indicazione \ac{iupac}:
-\begin{zitat}[{\ac{iupac} Green Book {\cite[][p.\,51]{iupac:greenbook}}}]
- In writing the formula for a complex ion, spacing for charge number can be added
- (staggered arrangement), as well as parentheses: \ch[charge-hshift=full]{SO4^2-},
- \ch{(SO4)^2-} The staggered arrangement is now recommended.
-\end{zitat}
-
-\subsection{Legami}\label{ssec:bonds}\secidx[Legami]{Formule brute}
-\subsubsection{Legami nativi}
-Vi sono tre tipi di quelli chiamati d'ora in poi \enquote{legami nativi}.
-\begin{beispiel}
- singolo: \ch{CH3-CH3} \\
- doppio: \ch{CH2=CH2} \\
- triplo: \ch{CH+CH}
-\end{beispiel}
-
-\subsubsection{Legami flessibili}
-\paragraph{Predefiniti}
-Oltre i tre legami nativi ve ne sono alcuni altri che possono essere richiamati
-tramite
-\begin{beschreibung}
- \Befehl{bond}{<bond name>}
-\end{beschreibung}
-I tipi predefiniti sono mostrati nella tabella~\ref{tab:bond_types}.
-
-\begin{table}
- \centering
- \caption{Legami disponibili con \protect\cmd{bond}.}
- \label{tab:bond_types}
- \begin{tabular}{lcl}
- \toprule
- \bfseries Nome & \bfseries Aspetto & \bfseries Alias \\
- \midrule
- \code{single} & \bond{single} & \code{normal}, \code{sb} \\

- \code{<co} & \bond{<co} & \code{coordleft} \\
- \bottomrule
- \end{tabular}
-\end{table}
-
-\begin{beispiel}
- \ch{C\bond{sb}C\bond{db}C\bond{tp}C\bond{deloc}C\bond{tdeloc}C\bond{co>}C\bond{<co}C}
-\end{beispiel}
-
-\paragraph{Legami personalizzati}
-\chemformula offre dei comandi per definire dei tipi di legame personali:
-\begin{beschreibung}
- \Befehl{DeclareChemBond}{<name>}\ma{<code>}
- \Befehl{RenewChemBond}{<name>}\ma{<code>}
- \Befehl{DeclareChemBondAlias}{<new name>}\ma{<old name>}
- \Befehl{ShowChemBond}{<name>}
-\end{beschreibung}
-Il loro uso è facilmente descritto da un esempio. Vediamo come sono definiti il
-legame \code{single} ed il legame \code{co>}:
-\begin{beispiel}[code only]
- \DeclareChemBond{single}
- { \draw[chembond] (chemformula-bond-start) -- (chemformula-bond-end) ; }
- \DeclareChemBond{coordright}
- { \draw[chembond,butt cap->] (chemformula-bond-start) -- (chemformula-bond-end) ; }
- \DeclareChemBondAlias{co>}{coordright}
-\end{beispiel}
-Due punti sono importanti: i nomi delle coordinate di partenza e di arrivo,
-\code{chemformula-bond-start} e \code{chemformula-bond-end}, e lo stile \TikZ
-dei legami \code{chembond}.
-
-Supponiamo di voler definire un particolare tipo di legame tratteggiato, ad
-esempio nel modo seguente:
-\begin{beispiel}
- \usetikzlibrary{decorations.pathreplacing}
- \makeatletter
- \DeclareChemBond{dashed}
- {
- \draw[
- chembond,
- decorate,
- decoration={ticks,segment length=\chemformula@bondlength/10,amplitude=1.5pt}]
- (chemformula-bond-start) -- (chemformula-bond-end) ;
- }
- \makeatother
- \chemsetup[chemformula]{bond-length=2ex}
- \ch{C\bond{dashed}C}
-\end{beispiel}
-
-L'ultimo esempio mostra un'ulteriore macro: \makeatletter\cmd{chemformula@bondlength}\makeatother.
-Esiste solamente per accedere direttamente alla lunghezza di legame impostata
-direttamente con \key{bond-length}.% (vedi anche a pagina~\pageref{key:bond-length}).
-
-\subsection{Personalizzazione}\secidx[Personalizzazione]{Formule brute}\label{ssec:compounds:customization}
-Le seguenti opzioni permettono di adattare l'output:
-\begin{beschreibung}
- \option{subscript-vshift}{<dim>} Ulteriore spostamento verticale dei pedici.
- Default = \code{0pt}
- \option{subscript-style}{text|math} Stile usato per i pedici. Default = \code{text}
- \option{charge-hshift}{<dim>} Spostamento degli apici seguenti un pedice. Default
- = \code{.25em}\label{desc:charge-hshift}
- \option{charge-style}{text|math} Stile usato per gli apici. Default = \code{text}
- \option{adduct-space}{<dim>} Spazio vuoto ai lati del punto di addotto. Default
- = \code{.1333em}
- \option{bond-length}{<dim>} Lunghezza dei legami. Default = \code{.5833em}.
- \option{bond-offset}{<dim>} Distanza tra atomo e legame. Default = \code{.07em}
- \option{bond-style}{<tikz>} Opzioni di \TikZ\ per i legami. Inizialmente vuoto.
- \option{radical-style}{<tikz>} Opzioni di \TikZ\ per il punto radicalico.
- Inizialmente vuoto.
- \option{radical-radius}{<dim>} Il raggio del punto radicalico. Default = \code{.2ex}
- \option{radical-hshift}{<dim>} Spazio orizzontale precedente il punto
- radicalico. Default = \code{.15em}
- \option{radical-vshift}{<dim>} Posizione verticale del punto radicalico
- riferita all'attuale linea di base. Default = \code{.5ex}
- \option{radical-space}{<dim>} Spazio orizzontale seguente il punto radicalico.
- Default = \code{.15em}
-\end{beschreibung}
-
-Forse l'utente si sarà accorto che per alcuni ioni le cariche sono spostate a
-destra:\secidx[Cariche!Spostamento]{Formule brute}
-\begin{beispiel}
- \ch{SO4^2-} \ch{NH4+} \ch{Na+}
-\end{beispiel}
-Queste vengono spostate quando \emph{seguono} un pedice, seguendo la
-raccomandazione \ac{iupac}~\cite[][p.\,51]{iupac:greenbook}. La dimensione dello
-spostamento può essere impostata con l'opzione \key{charge-hshift}.
-\begin{beispiel}
- \ch{SO4^2-} \ch{NH4+} \ch{Na+} \\
- \chemsetup[chemformula]{charge-hshift=.5ex}
- \ch{SO4^2-} \ch{NH4+} \ch{Na+} \\
- \chemsetup[chemformula]{charge-hshift=.5pt}
- \ch{SO4^2-} \ch{NH4+} \ch{Na+}
-\end{beispiel}
-
-Nonostante l'indicazione \ac{iupac}, \chemformula nell'impostazione predefinita
-non genera apici completamente spostati, che a mio parere in alcuni casi sono di
-difficile lettura ed in altri casi di aspetto sgradevole. Trattandosi di una
-percezione soggettiva, \chemformula offre sia la possibilità di impostare un
-valore assoluto per lo spostamento che di spostare completamente l'apice.
-Nell'ultimo caso va impiegato \key{charge-hshift}{full}.
-\begin{beispiel}
- \ch[charge-hshift=0pt]{C5H11+} \ch[charge-hshift=0pt]{SO4^2-} \\
- \ch{C5H11+} \ch{SO4^2-} \\
- \ch[charge-hshift=1ex]{C5H11+} \ch[charge-hshift=1ex]{SO4^2-} \\
- \ch[charge-hshift=full]{C5H11+} \ch[charge-hshift=full]{SO4^2-}
-\end{beispiel}
-
-Se non si desidera rendere le cariche in modo testuale è possibile passare al
-modo matematico:
-\begin{beispiel}
- \ch{M^x+} \ch{SO4^2-} \\
- \chemsetup[chemformula]{charge-style = math}
- \ch{M^x+} \ch{SO4^2-}
-\end{beispiel}
-
-L'opzione \key{subscript-vshift} può essere impiegata per adattare lo spostamento
-verticale dei pedici.\secidx[Pedici!Spostamento]{Formule brute}
-\begin{beispiel}
- \ch{H2SO4} \ch{Na3PO4} \\
- \chemsetup[chemformula]{subscript-vshift=.5ex}
- \ch{H2SO4} \ch{Na3PO4} \\
- \chemsetup[chemformula]{subscript-vshift=-.2ex}
- \ch{H2SO4} \ch{Na3PO4}
-\end{beispiel}
-
-Si può inolte selezionare in quale modo verranno composti i pedici:
-\begin{beispiel}
- \ch{A_nB_m} \ch{H2SO4} \\
- \chemsetup[chemformula]{subscript-style = math}
- \ch{A_nB_m} \ch{H2SO4}
-\end{beispiel}
-
-Con l'opzione \key{adduct-space} è possibile variare lo spazio a sinistra e destra

-\section{Tipi speciali di input}\secidx{Tipi speciali di input}
-Esistono alcuni \enquote{tipi di input speciali}.
-
-\subsection{Token a input singolo}\secidx[Token a input singolo]{Tipi speciali di input}
-Questo tipo è composto da un singolo token compreso tra i seguenti:
-\begin{beschreibung}
- \befehl{ch}{ + } \ch{+} Genera un segno più tra formule se spaziato a destra e sinistra:\\
- \cmd{ch}{2 Na + Cl2} \ch{2 Na + Cl2}
- \befehl{ch}{ v } \ch{v} Simbolo per una precipitazione o la formazione di un solido: \cmd{ch}{BaSO4 v} \ch{BaSO4 v}
- \befehl{ch}{ \lstinline+^+ } \ch{^} Simbolo per la formazione di gas: \cmd{ch}{\lstinline=H2 ^=} \ch{H2 ^}
-\end{beschreibung}
-
-Lo spazio a sinistra e destra del più può essere adattato tramite un'opzione:
-\begin{beschreibung}
- \option{plus-space}{<skip>} Una lunghezza elastica. Default =
- \code{.3em plus .1em minus .1em}
-\end{beschreibung}
-\begin{beispiel}
- \ch{A + B}\\
- \ch[plus-space=4pt]{A + B}
-\end{beispiel}
-
-\subsection{Input di opzioni}\secidx[Input di opzioni]{Tipi di input speciali}
-Talvolta si desidera applicare un'opzione solo ad una parte di una reazione;
-naturalmente è possibile impiegare ripetutamente \cmd{ch}.
-\begin{beispiel}
- \ch{H2O +}\textcolor{red}{\ch{H2SO4}}\ch{-> H3O+ + HSO4-} \\
- \ch{H2O +}\ch[subscript-vshift=2pt]{H2SO4}\ch{-> H3O+ + HSO4-}
-\end{beispiel}
-Tuttavia questo interrompe l'input nel sorgente e \emph{potrebbe} influenzare la
-spaziatura. Per questo motivo esiste un'alternativa:
-\begin{beschreibung}\makeatletter
- \befehl{ch}{ @\{<options>\} } Le opzioni date sono attive \emph{solo} fino alla
- fine della \emph{prossima} formula bruta.
-\end{beschreibung}
-\begin{beispiel}
- \ch{H2O +}\textcolor{red}{\ch{H2SO4}}\ch{-> H3O+ + HSO4-} \\
- \ch{H2O + @{format=\color{red}} H2SO4 -> H3O+ + HSO4-} \\
- o naturalmente:\\
- \ch{H2O + \textcolor{red}{H2SO4} -> H3O+ + HSO4-}\\[1em]
- \ch{H2O +}\ch[subscript-vshift=2pt]{H2SO4}\ch{-> H3O+ + HSO4-} \\

-\section{Input protetto}\secidx{Input protettto}
-In certi casi si può desiderare di evitare che \chemformula elabori l'input.
-Esistono due possibilità di ottenere proprio questo.
-
-\subsection{Testo}\label{ssec:text}\secidx[text]{Input protetto}
-Quando del testo viene posto tra \lstinline+" "+ oppure \lstinline+' '+ allora
-l'input viene considerato come testo normale ad eccezione per gli spazi: non sono
-ammessi e devono essere inseriti con \lstinline+~+.
-\begin{beschreibung}
- \Befehl{ch}{ "<escaped text>" }
- \Befehl{ch}{ '<escaped text>' }
-\end{beschreibung}
-\begin{beispiel}
- \ch{"\ox{2,Ca}" O} \\
- \ch{"\ldots\," Na + "\ldots\," Cl2 -> "\ldots\," NaCl} \\
- \ch{'A~->~B'}
-\end{beispiel}
-Questo stratagemma sarà necessario in pochi casi; ma quando risulta difficoltoso
-impiegare un comando all'interno di \cmd{ch} può essere utile applicare il modo protetto.
-
-\subsection{Matematica}\secidx[math]{Input protetto}
-Quando si ha dell'input matematico, è sufficiente porlo tra \lstinline+$ $+.
-L'output si distingue dal testo protetto (oltre che per il modo matematico)
-anche per la presenza di uno spazio in seguito. Il motivo è che suppongo che
-l'input matematico venga utilizzato soprattutto in luogo dei fattori
-stechiometrici.
-\begin{beschreibung}
- \Befehl{ch}{ \string$<escaped math>\string$ }
- \Befehl{ch}{ \string\(<escaped math>\string\) }
-\end{beschreibung}
-\begin{beispiel}
- escaped text: \ch{"$x$" H2O} \\
- escaped math: \ch{$x$ H2O} \\
- also escaped math: \ch{\(x\) H2O} \\
- \ch{$2n$ Na + $n$ Cl2 -> $2n$ NaCl}
-\end{beispiel}
-
-Lo spazio seguente l'input matematico protetto può essere adattato.
-\begin{beschreibung}
- \option{math-space}{<skip>} Una lunghezza elastica. Default =
- \code{.1667em plus .0333em minus .0117em}
-\end{beschreibung}
-\begin{beispiel}
- \ch{$2n$ Na + $n$ Cl2 -> $2n$ NaCl} \\
- \chemsetup[chemformula]{math-space=.25em}

-\section{Frecce}\label{sec:arrows}\secidx{Frecce}
-\subsection{Tipi di frecce}\secidx[Tipi]{Frecce}
-Le frecce vengono indicate nello stesso modo intuitivo di \paket{mhchem}. Ne esiste
-una serie:
-\begin{beschreibung}
- \befehl{ch}{ -> } \ch{->} freccia semplice a destra
- \befehl{ch}{ <- } \ch{<-} freccia semplice a sinistra
- \befehl{ch}{ -/> } \ch{-/>} non reagisce (destra)
- \befehl{ch}{ </- } \ch{</-} non reagisce (sinistra)
- \befehl{ch}{ <-> } \ch{<->} doppia freccia di mesomeria
- \befehl{ch}{ <> } \ch{<>} la reazione avviene in entrambe le direzioni
- \befehl{ch}{ == } \ch{==} equazione stechiometrica
- \befehl{ch}{ <=> } \ch{<=>} doppia freccia di equilibrio
- \befehl{ch}{ \lstinline+<=>>+ } \ch{<=>>} equilibrio spostato a destra
- \befehl{ch}{ \lstinline+<<=>+ } \ch{<<=>} equilibrio spostato a sinistra
- \befehl{ch}{ <o> } \ch{<o>} freccia isolobale
-\end{beschreibung}
-Tutte le frecce sono disegnate con \TikZ.
-\begin{beispiel}
- \ch{H2 + Cl2 -> 2 HCl} \\
- \ch{H2O + CO3^2- <=> OH- + HCO3-} \\
- \ch{A <- B} \\
- \ch{\{[CH2=CH-CH2]- <-> [CH2-CH=CH2]- \}} \\
- \ch{A <> B} \\
- \ch{H+ + OH- <=>> H2O} \\
- \ch{2 NO2 <<=> N2O4}
-\end{beispiel}
-
-\subsection{Etichettazione}\secidx[Etichettazione]{Frecce}
-Le frecce hanno due argomenti opzionali per essere etichettate.
-\begin{beschreibung}
- \Befehl{ch}{ ->[<above>][<below>] }
-\end{beschreibung}
-\begin{beispiel}
- \ch{A ->[a] B} \\
- \ch{A ->[a][b] B} \\
- \ch{A ->[\SI{100}{\celsius}] B}
-\end{beispiel}
-Il testo descrittivo può essere elaborato indipendentemente dalla freccia: basta
-usare degli spazi.
-\begin{beispiel}
- \ch{A ->[H2O] B} \\
- \ch{A ->[ H2O ] B} \\
- \ch{A ->[ "\ox{2,Ca}" F2 ] B} \\
- \ch{A ->[$\Delta$,~ \[H+ \]] B}
-\end{beispiel}
-
-Quando sono presenti degli spazi \chemformula elabora dapprima la parte tra
-parentesi come un input normale. Le frecce leggono i loro argomenti solo \emph{dopo}
-l'elaborazione. Come si può vedere, le frecce \enquote{crescono} con la lunghezza
-dell'etichetta, mentre rimane costante la parte eccedente. Nell'ultimo esempio si
-può inoltre vedere che le parentesi quadre all'interno degli argomenti dei comandi
-freccia devono essere inserite con \cmd{[} e \cmd{]}; naturalmente al di fuori di
-\cmd{ch} mantengono il loro comportamento normale. Questi comandi sono necessari
-perché il metodo solitamente impiegato di racchiudere le parentesi quadre tra
-parentesi graffe non funziona a causa del modo in cui \cmd{ch} legge il suo
-argomento.
-\begin{beispiel}
- \ch{A ->[a] B} \\
- \ch{A ->[ab] B} \\
- \ch{A ->[abc] B} \\
- \ch{A ->[abc~abc] B} \\
- % needs the `chemfig' package:
- \setatomsep{15pt}
- \ch{A ->[ "\chemfig{-[:30]-[:-30]OH}" ] B} \\
- \ch{A ->[[]] B} vs. \ch{A ->[\[\]] B}
-\end{beispiel}
-
-\subsection{Adattamento}\secidx[Adattamento]{Frecce}
-Con le opzioni seguenti è possibile adattare la resa grafica delle frecce:
-\begin{beschreibung}
- \option{arrow-offset}{<dim>} La lunghezza della freccia eccedente l'etichetta (a
- sinistra e destra). La lunghezza di una freccia vuota è il doppio di \code{arrow-offset}.
- Una lunghezza di \TeX. Default = \code{.75em}
-\option{arrow-min-length}{<dim>} La lunghezza minima che deve avere un errore,
- se tale lunghezza è inferiore al doppio di \key{arrow-offset} più la larghezza
- dell'etichetta. Default = \code{0pt}
- \option{arrow-yshift}{<dim>} Sposta una freccia verso l'alto (valore positivo) o
- verso il basso (valore negativo); una dimensione di \TeX. Default = \code{0pt}
- \option{arrow-ratio}{<factor>} Il rapporto tra le lunghezze delle frecce di equilibrio
- spostato: \code{.4} significa che la freccia più corta è lunga \num{0.4} volte
- la freccia più lunga. Default = \code{.6}
- \option{compound-sep}{<dim>} Lo spazio vuoto tra formule e freccia; una dimensione
- di \TeX. Default = \code{.5em}
- \option{label-offset}{<dim>} Lo spazio tra freccia ed etichette; una dimensione
- di \TeX. Default = \code{2pt}
- \option{label-style}{<font command>} Il corpo del font dell'etichetta. Default =
- \lstinline+\footnotesize+
-\end{beschreibung}
-
-Il codice seguente mostra gli effetti delle varie opzioni sulla freccia \lstinline+<=>>+:
-\begin{beispiel}
- standard: \ch{A <=>>[x][y] B} \\
- più lunga: \ch[arrow-offset=12pt]{A <=>>[x][y] B} \\
- più alta: \ch[arrow-yshift=2pt]{A <=>>[x][y] B} \\
- più bilanciata: \ch[arrow-ratio=.8]{A <=>>[x][y] B} \\
- etichetta più distante: \ch[label-offset=4pt]{A <=>>[x][y] B} \\
- distanza maggiore dalle formule: \ch[compound-sep=2ex]{A <=>>[x][y] B} \\
- etichette più piccole: \ch[label-style=\tiny]{A <=>[x][y] B}
-\end{beispiel}
-
-\subsection{Modificare i tipi di frecce}\label{sec:arrows_modify}\secidx[tipi!modificare]{Frecce}
-Le frecce sono definite attraverso il comando
-\begin{beschreibung}
- \Befehl{DeclareChemArrow}{<tokens>}\ma{<tikz>}
-\end{beschreibung}
-\ma{<tokens>} sono i simboli sostituiti dal codice proprio della freccia. Ad esempio,
-la freccia principale è stata definita attraverso
-\begin{beispiel}[code only]
- \DeclareChemArrow{->}{\draw[-cf] (cf_arrow_start) -- (cf_arrow_end) ;}
-\end{beispiel}
-Nel caso si desideri definire frecce proprie sono necessarie conoscenze fondamentali
-di \TikZ\footnote{Si rimanda alla guida \textsf{pgfmanual}.}. Si consiglia l'uso
-di alcune coordinate predefinite:
-\begin{description}
- \item[\code{(cf\_arrow\_start)}] L'inizio della freccia.
- \item[\code{(cf\_arrow\_end)}] La fine della freccia.
- \item[\code{(cf\_arrow\_mid)}] La metà della freccia.
- \item[\code{(cf\_arrow\_mid\_start)}] L'inizio della freccia più breve nelle freccie
- del tipo \lstinline+<=>>+.
- \item[\code{(cf\_arrow\_mid\_end)}] La fine della freccia più breve nelle freccie
- del tipo \lstinline+<=>>+.
- \item[\code{cf}, \code{left cf}, \code{right cf}] Punte di frecce definite per
- \chemformula.
-\end{description}
-\begin{beispiel}
- \DeclareChemArrow{.>}{\draw[-cf,dotted,red] (cf_arrow_start) -- (cf_arrow_end);}
- \DeclareChemArrow{n>}{\draw[-cf] (cf_arrow_start) .. controls ([yshift=3ex]cf_arrow_mid) .. (cf_arrow_end);}
- \ch{A .> B} \ch{A .>[a][b] B} \ch{A n> B}
-\end{beispiel}
-Quando si desidera ridefinire una freccia preesistente, è possibile usare uno dei
-due comandi seguenti:
-\begin{beschreibung}
- \Befehl{RenewChemArrow}{<tokens>}\ma{<tikz>}
- \Befehl{ShowChemArrow}{<tokens>}
-\end{beschreibung}
-Il secondo mostra la definizione attuale, il primo ridefinisce la freccia.
-\begin{beispiel}
- \texttt{\ShowChemArrow{->}} \\
- \RenewChemArrow{->}{\draw[->,red] (cf_arrow_start) -- (cf_arrow_end) ;}
- \texttt{\ShowChemArrow{->}} \\
- \ch{A -> B}

-\section{Didascalie di formule}\secidx{Didascalie di formule}
-\subsection{Sintassi}\secidx[sintassi]{Didascalie di formule}
-\chemformula ha una propria sintassi per scrivere del testo sotto ad una formula
-chimica, che funziona in modo analogo agli argomenti opzionali delle frecce.
-\begin{beschreibung}
- \Befehl{ch}{ !(<name>)( <formula> ) }
-\end{beschreibung}
-Quando un punto esclamativo viene seguito da una coppia di parentesi tonde,
-\chemformula fa il seguente:
-\begin{beispiel}
- \ch{!(ethanol)( CH2CH2OH )}
-\end{beispiel}
-
-Quel che vale per le etichette delle frecce vale anche qui: lasciando degli spazi
-le parti di input vengono elaborate a seconda del loro tipo prima che il testo
-venga scritto sotto la formula.
-\begin{beispiel}
- \ch{!(water)(H2O)} \quad
- \ch{!( "\textcolor{blue}{water}" )( H2O )} \quad
- \ch{!( $2n-1$ )( H2O )} \quad
- \ch{!( H2O )( H2O )} \quad
- \ch{!(oxonium)( H3O+ )}
-\end{beispiel}
-
-Se per qualche ragione si desidera avere un punto esclamativo \emph{senza} aggiungere
-un testo sotto una formula, è sufficiente evitare di farlo seguire da parentesi.
-\begin{beispiel}
- \ch{H2O~(!)} \\
- \ch{A!{}()}
-\end{beispiel}
-
-\subsection{Personalizzazione}\secidx[Personalizzazione]{Didascalie di formule}
-\chemformula mette a disposizione due opzioni per adattare il testo:
-\begin{beschreibung}
- \option{name-format}{<commands>} Il formato del testo; può essere inserito un
- input qualunque. Default = \lstinline+\scriptsize\centering+
- \option{name-width}{<dim>|auto} La larghezza del box nel quale viene posto il
- testo: \code{auto} riconosce la larghezza della didascalia e imposta il box di
- conseguenza. Default = \code{auto}
-\end{beschreibung}
-\begin{beispiel}
- \ch{!(acido)( H2SO4 ) -> B} \\
- \ch[name-format=\sffamily\small]{!(acido)( H2SO4 ) -> B} \\
- \ch[name-format=\scriptsize N:~]{!(acido)( H2SO4 ) -> B} \\
- \ch[name-width=3em,name-format=\scriptsize\raggedright]{!(acido)( H2SO4 ) -> B}
-\end{beispiel}
-\secidx*{Didascalie di formule}
-
-\section{Formato e carattere}\label{sec:format}\secidx{Formato e carattere}
-Come impostazione predefinita \chemformula non varia l'output delle formule.
-Prendiamo come esempio un input privo di senso chimico per dimostrare tutte le
-capacità di \chemformula:
-\begin{beispiel}
- \newcommand*\sample{\ch{H2C-C+C-CH=CH+ + CrO4^2- <=>[x][y] 2.5 Cl^{-.} + 3_1/2 Na*OH_{(aq)} + !(name)( A^n ) "\LaTeXe"}}
- \sample
-\end{beispiel}
-\newcommand*\sample{\ch{H2C-C+C-CH=CH+ + CrO4^2- <=>[x][y] 2.5 Cl^{-.} + 3_1/2 Na*OH_{(aq)} + !(name)( A^n ) "\LaTeXe"}}
-Ora variamo alcuni aspetti del testo e osserviamo i risultati:
-\begin{beispiel}[below]
- \sffamily Ciao \sample \\
- \ttfamily Ciao \sample \normalfont \\
- \bfseries Ciao \sample \normalfont \\
- \itshape Ciao \sample
-\end{beispiel}
-Come si osserva la maggior parte delle funzioni adattano le caratteristiche del
-font circostante.
-
-Quando si vuole cambiare questo comportamento preimpostato oppure il formato di
-default è possibile usare la seguente opzione:
-\begin{beschreibung}
- \option{format}{<anything>} Inserisce il codice desiderato all'inizio del comando
- \cmd{ch}.
-\end{beschreibung}
-\begin{beispiel}
- % blu e privo di grazie:
- \definecolor{newblue}{rgb}{.1,.1,.5}\chemsetup[chemformula]{format=\color{newblue}\sffamily}
- \sffamily Ciao \sample \\
- \ttfamily Ciao \sample \normalfont \\
- \bfseries Ciao \sample \normalfont \\
- \itshape Ciao \sample
-\end{beispiel}
-
-Si possono inoltre variare specificatamente la famiglia, la serie e la forma del
-font dell'output:
-\begin{beschreibung}
- \option{font-family}{<family>} Varia la famiglia con: \lstinline+\fontfamily{<family>}\selectfont+.
- \option{font-series}{<series>} Varia la serie con: \lstinline+\fontseries{<series>}\selectfont+.
- \option{font-shape}{<shape>} Varia la forma con \lstinline+\fontshape{<shape>}\selectfont+.
-\end{beschreibung}
-\begin{beispiel}
- % sempre in nero:
- \chemsetup[chemformula]{font-series=bx}
- Ciao \sample \\
- \sffamily Ciao \sample \normalfont \\
- \chemsetup[chemformula]{font-family=lmr,font-series=m} Ciao \sample \normalfont \\
- \itshape Ciao \sample
-\end{beispiel}
-
-Quando si impiegano \XeLaTeX\ oppure \LuaLaTeX\ avendo caricato il pacchetto
-\paket{fontspec}, è possibile variare il carattere di \chemformula anche nel
-modo seguente:
-\begin{beschreibung}
- \Option{font-spec}{\{<font>\}} oppure con opzioni
- \Option{font-spec}{\{[<options>]<font>\}}
-\end{beschreibung}
-\begin{beispiel}

-\section{Pittogrammi}\secidx{Pittogrammi}
-\subsection{Le immagini}
-Il \ac{ghs} contiene alcuni pittogrammi:
-
-\ghspic{explos} \ghspic{flame} \ghspic{flame-O} \ghspic{bottle} \ghspic{acid}
-\ghspic{skull} \ghspic{exclam} \ghspic{health} \ghspic{aqpol}
-
-Il comando

-li carica. La tabella~\ref{tab:ghs_pictograms} mostra tutti i pittogrammi e i nomi
-dei loro file, o meglio: mostra i nomi dei file da utilizzare con il comando \cmd{ghspic}.
-In realtà i file si chiamano \lstinline=ghsystem_<name>.<filetype>=, dove
-\code{<filetype>} è un'estensione tra \code{eps}, \code{pdf}, \code{jpg}
-oppure \code{png}, vedi anche il paragrafo~\ref{ssec:picture_type}.
-\begin{beispiel}
- \ghspic{skull}
-\end{beispiel}
-
-Se si preferisce variare la dimensione, è disponibile l'opzione
-\begin{beschreibung}
- \option{scale}{<factor>} Scala il pittogramma. Default = \code{1}
-\end{beschreibung}
-Le immagini originali sono piuttosto grandi. La preimpostazione (fattore = $1$)
-scala le immagini ad un ventesimo della loro dimensione reale.
-\begin{beispiel}
- \ghspic[scale=2]{skull}
-\end{beispiel}

-\subsection{Il tipo dell'immagine dipende dal compilatore}\label{ssec:picture_type}
-L'utente probabilmente è a conoscenza che non tutti i tipi di immagini sono compatibili
-con ciascun compilatore. \pdfTeX{} in modalità \acs{dvi} richiede file di tipo
-\code{eps}, mentre \pdfTeX{} in modalità \acs{pdf}, \XeTeX{} e \LuaTeX{} convertono
-file di tipo \code{eps} in \code{pdf}, ammesso che l'utente abbia diritti di scrittura
-nella cartella contenente le immagini. Gli ultimi elencati sanno tuttavia
-includere immagini di tipo \code{jpg} e \code{png} senza problemi, mentre
-\pdfTeX{} in modalità \acs{dvi} non ne è capace.
-
-Per risolvere il problema \ghsystem verifica quale compilatore viene utilizzato,
-e nel caso di \pdfTeX{} anche la modalità di utilizzo; poi sceglie quale immagine
-utilizzare tra \code{eps} e \code{png} per i pittogrammi. In ogni caso il tipo di
-immagine può essere selezionato a piacimento attraverso l'opzione
-\begin{beschreibung}
- \Option{pic-type}{eps|pdf|jpg|png}
-\end{beschreibung}
-\secidx*{Pittogrammi}
-
-\section{Lingue disponibili}\label{sec:ghsystem_language}
-Al momento attuale le frasi H e P sono disponibili solo in inglese, tedesco ed
-italiano. Il pacchetto reagisce all'opzione \key[option]{italian} di \chemmacros,
-ma non riconosce (ancora) la lingua impostata con \paket{babel} o \paket{polyglossia}.
-
-È possibile scegliere la lingua anche in modo esplicito.
-\begin{beschreibung}
- \Option{language}{english|german|italian}
-\end{beschreibung}
-\begin{beispiel}
- \ghs{h}{201}
-
- \chemsetup[ghsystem]{language=english}
- \ghs{h}{201}
-\end{beispiel}
-
-È mia intenzione implementare ulteriori lingue in futuro; tuttavia potrebbe volerci
-ancora del tempo. Chi volesse partecipare a \ghsystem e trascrivere le frasi in
-un'altra lingua, è invitato a contattarmi%
-\footnote{\href{mailto:contact@mychemistry.eu}{contact@mychemistry.eu}};
-gli metterò a disposizione un file template, un \acs{pdf} contenenti le traduzioni
-officiali ed ogni ulteriore aiuto necessario.

-\section{Lista delle frasi}\secidx{Lista delle frasi}
-Se si desidera elencare tutte le frasi, è possibile utilizzare il comando
-\begin{beschreibung}
- \Befehl{ghslistall}[<options>]
-\end{beschreibung}
-
-Questo comando crea una tabella di tutte le frasi nell'ambiente \lstinline=longtable=
-del pacchetto \paket{longtable}. Il suo aspetto può essere adattato con le opzioni
-seguenti.
-\begin{beschreibung}
- \option{table-head-number}{<text>} Default = \code{Numero}
- \option{table-head-text}{<text>} Default = \code{Frase}
- \option{table-next-page}{<text>} Default = \code{Continua nella prossima pagina}
- \option{table-caption}{<text>} Didascalia della tabella. Default = \code{Elenco
- di tutte le frasi H, EUH e P.}
- \option{table-caption-short}{<text>} \code{<short>} in \lstinline=\caption[<short>]{<text>}=.
- \option{table-label}{<text>} L'etichetta per l'uso di riferimenti incrociati con
- i comandi del tipo di \lstinline=\ref=. Default = \code{tab:ghs-hp-statements}
- \option{table-row-sep}{<dim>} Distanza tra le righe. Una dimensione di \TeX.
- Default = \code{3pt}
- \option{table-rules}{\default{default}|booktabs|none} Lo stile delle righe
- orizzontali della tabella. \code{default} utilizza \lstinline=\hline=, \code{booktabs}
- utilizza \lstinline=\toprule=, \lstinline=\midrule= e \lstinline=\bottomrule=.
- Questa opzione richiede che sia caricato il pacchetto \paket{booktabs}. Default
- = \code{default}
- \option{table-top-head-rule}{\default{default}|booktabs|none} Varia la riga in
- modo esplicito. Default = \code{default}

+\section{Introduction}
+As a chemist you are probably aware of the fact that the \acl{UN} have
+developed the \ac{ghs} as a global replacement for the various different
+systems in different countries. While it has not been implemented by all
+countries yet~\cite{unece:ghsystem_implementation}, it is only a matter of
+time.
+
+The package \ghsystem now enables you to typeset all the hazard and
+precautionary statements and pictograms in a very easy way. The statements
+are taken from \acs{eu} regulation 1272/2008~\cite{eu:ghsystem_regulation}.
+
+\section{Licence and Requirements}
+Permission is granted to copy, distribute and/or modify this software under
+the terms of the \LaTeX\ project public license (lppl) version 1.3 or later
+(\url{http://www.latex-project.org/lppl.txt}). The package has the status
+``maintained.''
+
+\ghsystem\ loads the following packages:
+\paket*{expl3}\footnote{\CTANurl{l3kernel}}, \paket*{xparse} and
+\paket*{l3keys2e}\footnote{\CTANurl{l3packages}}, \paket*{translations} (from
+the \paket{exsheets} bundle), \paket{siunitx}, \paket{graphicx},
+\paket{longtable} and \paket{ifpdf}.
+
+\section{Setup}
+The simplest way is to load \chemmacros\ which loads \ghsystem\ implicitily.
+All of \ghsystem's options belong to the module
+\textcolor{module}{\code{ghsystem}}. This means they can be setup with
+\begin{beispiel}[code only]
+ \chemsetup[ghsystem]{<options>} or
+ \chemsetup{ghsystem/<option1>,ghsystem/<option2>}
+\end{beispiel}
+\sinceversion{4.0}However, \ghsystem\ can be loaded as a standalone package
+and thus provides its own setup command:
+\begin{beschreibung}
+ \Befehl{ghssystem}{<options>}
+\end{beschreibung}
+
+\section{Get Hazard and Precautionary Statements}\secidx{Hazard and Precautionary Statements}
+\subsection{Simple Statements}\secidx[get statements]{GHSYSTEM}
+The general usage is simple: you use the command
+\begin{beschreibung}
+ \Befehl{ghs}*[<options>]{<type>}\ma{<number>}
+\end{beschreibung}
+There are three types available: \code{h}, \code{euh} and \code{p}. The
+\ma{<type>} argument is case insensitive, so just type them in as you like.
+\begin{beispiel}
+ \ghs{h}{200} \\
+ \ghs{H}{224} \\
+ \ghs{euh}{001} \\
+ \ghs{Euh}{202} \\
+ \ghs{p}{201}
+\end{beispiel}
+
+The starred version hides the identifier and only gives the statement. If you
+want to hide the statement itself instead you can use the option:
+\begin{beschreibung}
+ \Option{hide}{\default{true}|false}\Default{false}
+ Hide the statement.
+\end{beschreibung}
+
+There is an option to customize the output, too.
+\begin{beschreibung}
+ \Option{space}{<space command>}\Default{}
+ Space between \code{<type>} and \code{<number>}.
+\end{beschreibung}
+\begin{beispiel}
+ \ghs{h}{200} \\
+ \ghs[space=\,]{h}{200} \\
+ \ghs*{h}{200} \\
+ \ghs[hide]{h}{200}
+\end{beispiel}
+
+\subsection{Statements with Placeholders}\secidx[statements with placeholders]{GHSYSTEM}
+Some of the statements contain placeholders. They can be one of the
+following:
+\begin{itemize}
+ \item \textit{\textless state route of exposure if it is conclusively proven that
+ no other routes of exposure cause the hazard\textgreater}
+ \item \textit{\textless state specific effect if known\textgreater}
+ \item \textit{\textless or state all organs affected, if known\textgreater}
+ \item \textit{\textless name of sensitising substance\textgreater}
+\end{itemize}
+
+Except the last one which needs to be filled in, they are hidden per default.
+They can be made visible with the option
+\begin{beschreibung}
+ \Option{fill-in}{\default{true}|false}\Default{false}
+ Show placeholders.
+\end{beschreibung}
+\begin{beispiel}[below]
+ \ghs{h}{340} \\
+ \ghs[fill-in]{h}{340} \\
+ \ghs{h}{360} \\
+ \ghs[fill-in]{h}{360} \\
+ \ghs{h}{370} \\
+ \ghs[fill-in]{h}{370} \\
+ \ghs{euh}{208} \\
+ \ghs[fill-in]{euh}{208}
+\end{beispiel}
+
+These placeholders can be replaced with one of these options:
+\begin{beschreibung}
+ \Option{exposure}{<text>}\Default{}
+ exposure placeholder
+ \Option{effect}{<text>}\Default{}
+ effect placeholder
+ \Option{organs}{<text>}\Default{}
+ organ placeholder
+ \Option{substance}{<text>}\Default{}
+ substance placeholder
+\end{beschreibung}
+\begin{beispiel}
+ \ghs[exposure=This is how you get exposed.]{h}{340} \\
+ \ghs[effect=These are the effects.]{h}{360} \\
+ \ghs[organs=to this organ]{h}{370} \\
+ \ghs[substance=substance]{euh}{208}
+\end{beispiel}
+
+\subsection{Statements with Gaps}\secidx[statements with gaps]{GHSYSTEM}
+Some of the statements have gaps that can be filled.
+\begin{beispiel}
+ \ghs{p}{301} \\
+ \ghs{p}{401} \\
+ \ghs{p}{411} \\
+ \ghs{p}{413}
+\end{beispiel}
+
+These gaps can be filled using these options:
+\begin{beschreibung}
+ \Option{text}{<text>}
+ \Option{dots}{<text>}
+ \Option{C-temperature}{<num>}
+ \Option{F-temperature}{<num>}
+ \Option{kg-mass}{<num>}
+ \Option{lbs-mass}{<num>}
+\end{beschreibung}
+\begin{beispiel}
+ \ghs[text=contact physician!]{p}{301} \\
+ \ghs[dots=here]{p}{401} \\
+ \ghs[C-temperature=50, F-temperature=122]{p}{411} \\
+ \ghs[kg-mass=5.0, lbs-mass=11, C-temperature=50, F-temperature=122]{p}{413}
+\end{beispiel}
+
+\subsection{Combined Statements}\secidx[combined statements]{GHSYSTEM}
+There are some combinations of statements. They are input with a \code{+}
+between the numbers:
+\begin{beispiel}[below]
+ \ghs{p}{235+410} \\
+ \ghs{p}{301+330+331}
+\end{beispiel}
+
+Note that you can only get combinations that officially exist. \emph{You
+ can't combine freely}.
+\secidx*{Hazard and Precautionary Statements}
+
+\section{Pictograms}\secidx{Pictograms}
+\subsection{The Pictures}
+The \ac{ghs} defines a number of pictograms:
+
+\ghspic{explos} \ghspic{flame} \ghspic{flame-O} \ghspic{bottle} \ghspic{acid}
+\ghspic{skull} \ghspic{exclam} \ghspic{health} \ghspic{aqpol}
+
+The command
+\begin{beschreibung}
+ \Befehl{ghspic}[<options>]{<name>}
+\end{beschreibung}
+loads them. Table~\ref{tab:ghs_pictograms} shows all available pictograms and
+their names. To be more precise: it shows the names to use with the
+\cmd{ghspic} command. The file names are
+\lstinline=ghsystem_<name>.<filetype>= where \code{<filetype>} is \code{eps},
+\code{pdf}, \code{jpg} or \code{png}, see also
+section~\ref{ssec:picture_type}.
+\begin{beispiel}
+ \ghspic{skull}
+\end{beispiel}
+
+If you don't like the default size you can change it using this option:
+\begin{beschreibung}
+ \Option{scale}{<factor>}\Default{1}
+ Scales the pictogram.
+\end{beschreibung}
+The pictures are actually quite large. The default setting scales them by a
+factor
+of $\frac{1}{20}$.
+\begin{beispiel}
+ \ghspic[scale=2]{skull}
+\end{beispiel}
+
+If you want to use some specific \lstinline=\includegraphics= options, \eg, if
+you want to rotate the pictogram for some reason, use this option:
+\begin{beschreibung}
+ \Option{includegraphics}{\{<includegraphics keyvals>\}}
+\end{beschreibung}
+\begin{beispiel}
+ \ghspic[includegraphics={angle=90}]{skull}
+\end{beispiel}
+
+\begin{longtable}{>{\ttfamily}ll>{\ttfamily}ll}

+\end{longtable}
+
+\subsection{Picture Type Depending on Engine}\label{ssec:picture_type}
+As you probably know you can't use every picture type with every compiler
+engine. \pdfTeX{} in \acs{dvi} mode \emph{needs} \code{eps} pictures while
+\pdfTeX{} in \acs{pdf} mode, \XeTeX{} and \LuaTeX{} convert \code{eps}
+pictures into \code{pdf} files, given they have the rights to write in the
+directory the pictures are saved in.
+
+However, the latter can include \code{jpg} and \code{png} without any
+problems, while \pdfTeX{} in \acs{dvi} mode can't.
+
+To resolve this \ghsystem tests which engine is used and if \pdfTeX{} which
+mode is used and then chooses either \code{eps} or \code{pdf} for the
+pictograms. You are free to choose the picture type yourself with the option
+\begin{beschreibung}
+ \Option{pic-type}{eps|pdf|jpg|png}
+\end{beschreibung}
+\secidx*{Pictograms}
+
+\section{Available Languages}\label{sec:ghsystem_language}
+Right now the H and P statements are only available in English, German or
+Italian. The package adapts \chemmacros' option \key[option]{language} or if
+the option hasn't been used recognizes the language settings made with
+\paket{babel} or \paket{polyglossia}. To be more precise: the language
+selected at begin document is recognized. Later changes won't affect
+\ghsystem. If you want to use different languages you have to use
+\ghsystem's language option then.
+
+You can also choose the language explicitly.
+\begin{beschreibung}
+ \Option{language}{english|german|italian}\Default{english}
+ Selects and loads language file. Falls back to \code{english} if the
+ chosen file doesn't exist.
+\end{beschreibung}
+\begin{beispiel}
+ \ghs{h}{201}
+
+ \chemsetup[ghsystem]{language=german}
+ \ghs{h}{201}
+\end{beispiel}
+
+% TODO: \loadghsystemlanguage
+
+I will add other languages some time in future. This may take a while,
+though. If you would be willing to contribute and write the statements of
+another language please feel free to contact
+me\footnote{\href{mailto:contact@mychemistry.eu}{contact@mychemistry.eu}}. I
+would provide you with a template file, a \acs{pdf} containing the official
+translations, and help to all your questions.
+
+\section{List of All Statements}\secidx{List of All Statements}
+If for some reason you want to list all sentences you can use
+\begin{beschreibung}
+ \Befehl{ghslistall}[<options>]
+\end{beschreibung}
+
+This command has a number of options to customize the table, which is created with
+the \lstinline=longtable= environment of the \paket{longtable} package.
+\begin{beschreibung}
+ \Option{table-head-number}{<text>}\Default{Identifier}
+ \Option{table-head-text}{<text>}\Default{Statement}
+ \Option{table-next-page}{<text>}\Default{continues on next page}
+ \Option{table-caption}{<text>}\Default{All H, EUH, and P Statements.}
+ As \code{<text>} in \lstinline=\caption{<text>}=.
+ \Option{table-caption-short}{<text>}\Default{}
+ As \code{<short>} in \lstinline=\caption[<short>]{<text>}=.
+ \Option{table-label}{<text>}\Default{tab:ghs-hp-statements}
+ The label to refer to the table with \lstinline=\ref= and similar
+ commands.
+ \Option{table-row-sep}{<dim>}\Default{3pt}
+ The separation of the table rows. A \TeX\ dimension.
+ \Option{table-rules}{\default{default}|booktabs|none}\Default{default}
+ The style of the horizontal rules in the table. \code{default} uses
+ \lstinline=\hline=, \code{booktabs} uses \lstinline=\toprule=,
+ \lstinline=\midrule= or \lstinline=\bottomrule=, resp. This option needs
+ the \paket{booktabs} package which you have to load yourself then.
+ \Option{table-top-head-rule}{\default{default}|booktabs|none}\Default{default}
+ Change top rule explicitly.
+ \Option{table-head-rule}{\default{default}|booktabs|none}\Default{default}
+ Change rule below head explicitly.
+ \Option{table-foot-rule}{\default{default}|booktabs|none}\Default{default}
+ Change foot rule explicitly.
+ \Option{table-last-foot-rule}{\default{default}|booktabs|none}\Default{default}
