+\section{Lizenz, Voraussetzungen}
+\makeatletter\CM@name\ v\CM@version\makeatother\ steht unter der \LaTeX\ Project Public License Version 1.3 oder später.\newline(\url{http://www.latex-project.org/lppl.txt})
+
+\CMname\ ruft intern die Pakete \paket{xkeyval}, \paket{amsmath} und `tikz' (Ti\textbf{\textit{k}}Z = \paket{pgf}) auf. Sind sie nicht vorhanden, wird eine Fehlermeldung ausgegeben.
+
+Manche Befehle haben allerdings unterschiedliche Definitionen, je nachdem ob andere Pakete vom Benutzer \emph{vorher} geladen wurden oder nicht. Manche Befehle werden auch nur definiert, wenn ein bestimmtes Paket geladen ist. Das betrifft die Pakete \paket{mhchem}, \paket{siunitx} und \paket{chemstyle} sowie die Befehle aus Abschnitt \ref{sec:teilchen}, \lstinline=\ox= (Abschnitt \ref{ssec:oxidationszahlen}), die Befehle aus Abschnitt \ref{sec:standardstate} und die Umgebungenen aus Abschnitt \ref{sec:mhchem}.
+
+Für die Paketoption \lstinline=xspace= (Abschnitt \ref{sec:optionen}) wird das Paket \paket{xspace} benötigt.
+
+Wenn der Benutzer das Paket `mhchem' \emph{vor} \CMname\ lädt, so werden außerdem die Pakete \paket{mathtools} und \paket{environ} benötigt.
+
+Für den \lstinline=\redox=-Befehl (Abschnitt \ref{sec:redoxreaktionen}) und den \lstinline=\newman=-Befehl (Abschnitt \ref{sec:newman} muss die Tikzlibrary `calc' eingebunden werden.
+
+Volle Funktionalität steht also mit folgender oder ähnlicher Präambel bereit:
+\begin{lstlisting}
+ \usepackage{siunitx,chemstyle}
+ \usepackage[version=3,arrows=pgf]{mhchem}
+ \usepackage[xspace=true]{chemmacros}
+ \usetikzlibrary{calc}
+\end{lstlisting}
+
+\section{Teilchen, Ionen und ein Symbol}\label{sec:teilchen}
+Eine Reihe einfacher Makros, um häufig gebrauchte Teilchen sowie ein Symbol darzustellen:
+\begin{itemize}
+ \item\lstinline=\Hpl= \Hpl (Proton)
+ \item\lstinline=\Hyd= \Hyd (Hydroxid)
+ \item\lstinline=\HtO= \HtO (Oxonium)
+ \item\lstinline=\el= \el (Elektron)
+ \item\lstinline=\prt= \prt (Proton)
+ \item\lstinline=\ntr= \ntr (Neutron)
+ \item\lstinline=\transitionstatesymbol= \transitionstatesymbol\ Über\-gangs\-zu\-stands\-symbol (verwendet Ti\textbf{\textit{k}}Z)
+\end{itemize}
+Diese Befehle sind sowohl im Text- wie im Mathematikmodus einsetzbar. Je nachdem, ob `mhchem' geladen wurde oder nicht, werden die ersten drei Teilchen mit dem \lstinline=\cf{}=-Befehl von `mhchem' oder mit \lstinline=\ensuremath{\text{}}= geschrieben.
+
+\section{Stereo-Deskriptoren, Nomenklatur}\label{sec:stereo}
+Die folgenden Makros sollen das Schreiben von IUPAC-Namen etwas erleichtern:
+\begin{itemize}
+ \item Cahn-Ingold-Prelog:
+ \begin{itemize}
+ \item\lstinline=\Rcip= \Rcip
+ \item\lstinline=\Scip= \Scip
+ \item\lstinline=\cip{<conf>}= z.\,B.: \lstinline=\cip{R,S}= \cip{R,S}
+ \end{itemize}
+ \item Fischer:
+ \begin{itemize}
+ \item\lstinline=\Dfi= \Dfi
+ \item\lstinline=\Lfi= \Lfi
+ \end{itemize}
+ \item cis/trans u. zusammen/entgegen:
+ \begin{itemize}
+ \item\lstinline=\Z= \Z
+ \item\lstinline=\E= \E
+ \item\lstinline=\cis= \cis
+ \item\lstinline=\trans= \trans
+ \end{itemize}
+ \item ortho/meta/para:
+ \begin{itemize}
+ \item\lstinline=\ortho= \ortho
+ \item\lstinline=\meta= \meta
+ \item\lstinline=\para= \para
+ \end{itemize}
+\end{itemize}
+Anzeigen der absoluten Konfiguration (verwendet Ti\textbf{\textit{k}}Z):
+\begin{itemize}
+ \item\lstinline=\Rconf[<letter>]= \lstinline=\Rconf=: \Rconf \quad\lstinline=\Rconf[]=: \Rconf[]
+ \item\lstinline=\Sconf[<letter>]= \lstinline=\Sconf=: \Sconf \quad\lstinline=\Sconf[]=: \Sconf[]
+\end{itemize}
+
+\begin{lstlisting}
+ \Dfi-Weinsäure = \cip{2S,3S}-Weinsäure, \Dfi-($-$)-Threose = \cip{2S,3R}-($-$)-2,3,4-Trihydroxybutanal\\
+ \cis-2-Buten = \Z-2-Buten, \cip{2E,4Z}-Hexadien\\
+ \meta-Xylol = 1,3-Dimethylbenzol
+
+ % mit `bpchem'-Befehl \IUPAC:
+ \IUPAC{\Dfi-Wein\|säure} = \IUPAC{\cip{2S,3S}-Wein\|säure}, \IUPAC{\Dfi-($-$)-Threose} = \IUPAC{\cip{2S,3R}-($-$)-2,3,4\-Tri\|hydroxy\|butanal}
+\end{lstlisting}
+\Dfi-Weinsäure = \cip{2S,3S}-Weinsäure, \Dfi-($-$)-Threose = \cip{2S,3R}-($-$)-2,3,4-Trihydroxybutanal\\
+\cis-2-Buten = \Z-2-Buten, \cip{2E,4Z}-Hexadien\\
+\meta-Xylol = 1,3-Dimethylbenzol
+
+\IUPAC{\Dfi-Wein\|säure} = \IUPAC{\cip{2S,3S}-Wein\|säure}, \IUPAC{\Dfi-($-$)-Threose} = \IUPAC{\cip{2S,3R}-($-$)-2,3,4\-Tri\|hydroxy\|butanal}
+
+Im letzten Beispiel wurde der Befehl \lstinline=\IUPAC= des Pakets \paket{bpchem} eingesetzt.
+
+\section{Oxidationszahlen und (echte) Ladungen}\label{sec:ladungen}
+\subsection{Ionenladungen}\label{ssec:ionen}
+Einfaches Darstellen von Ladungen:
+\begin{itemize}
+ \item\lstinline=\pch[<number>]= positive Ladung (\textbf{p}lus + \textbf{ch}arge), \lstinline=\pch, Na\pch, Ca\pch[2]= \pch, Na\pch, Ca\pch[2]
+ \item\lstinline=\mch[<number>]= negative Ladung (\textbf{m}inus + \textbf{ch}arge), \lstinline=\mch, F\mch, S\mch[2]= \mch, F\mch, S\mch[2]
+\end{itemize}
+
+\subsection{Oxidationszahlen}\label{ssec:oxidationszahlen}
+Setzen von Oxidationszahlen:
+\begin{itemize}
+ \item\lstinline=\ox{<number>,<atom>}= setzt \lstinline=<number>= über \lstinline=<atom>=; \lstinline=\ox{+1,Na}=, \lstinline=\ox{+I,Na}=, \lstinline=\ox{-2,S}=, \lstinline=\ox{-II,S}= \ox{+1,Na}, \ox{+I,Na}, \ox{-2,S}, \ox{-II,S}
+\end{itemize}
+Wenn das Paket `mhchem' geladen wurde, wird \lstinline=<atom>= innerhalb des \lstinline=\cf=-Befehls gesetzt: \lstinline=\ox{+II,Ca}\ox{-I,F2}= \ox{+II,Ca}\ox{-I,F2}. Ohne `mhchem' funktioniert das so nicht {\makeatletter\def\oxNoMhchem#1#2{\ensuremath{\overset{\text{\tiny\CM@ox@sign#1}}{\text{#2}}}}\makeatother(\oxNoMhchem{+II}{Ca}\oxNoMhchem{-I}{F2}) und die konventionelle Methode muss verwendet werden: \lstinline=\ox{+II,Ca}\ox{-I,F$_2$}= \oxNoMhchem{+II}{Ca}\oxNoMhchem{-I}{F$_2$}}.
+
+\subsection{Partialladungen und ähnliches}\label{ssec:partialladungen}
+Vielleicht selten gebraucht, nichtsdestoweniger nützlich:
+\begin{itemize}
+ \item\lstinline=\delp= \delp (\textbf{del}ta + \textbf{p}lus)
+ \item\lstinline=\delm= \delm (\textbf{del}ta + \textbf{m}inus)
+\end{itemize}
+Diese Makros können zum Beispiel mit dem \lstinline=\ox=-Befehl eingesetzt werden oder zusammen mit dem Paket \paket{chemfig}:
+\begin{lstlisting}
+ \ox{\delp,H}\ox{\delm,Cl}\par
+ \chemfig{\chemabove[3pt]{\lewis{246,Br}}{\delm}-\chemabove[3pt]{H}{\delp}}
+\end{lstlisting}
+\ox{\delp,H}\ox{\delm,Cl}\par
+\chemfig{\chemabove[3pt]{\lewis{246,Br}}{\delm}-\chemabove[3pt]{H}{\delp}}
+
+Auch die beiden folgenden Makros sind v.a. beim Einsatz mit `chemfig' nützlich.
+\begin{itemize}
+ \item\lstinline=\scrp= \scrp (\textbf{scr}iptstyle + \textbf{p}lus)
+ \item\lstinline=\scrm= \scrm (\textbf{scr}iptstyle + \textbf{m}inus)
+\end{itemize}
+Zum Beispiel:
+\begin{lstlisting}
+ {\setatomsep{1.8em}\chemfig{CH_3-CH_2-\chemabove{\lewis{026,O}}{\hspace{5mm}\scrm}}}
+\end{lstlisting}
+{\setatomsep{1.8em}\chemfig{CH_3-CH_2-\chemabove{\lewis{026,O}}{\hspace{5mm}\scrm}}}
+
+\section{Redoxreaktionen}\label{sec:redoxreaktionen}
+\CMname\ stellt zwei Befehle zur Verfügung\footnote{Dank an \href{http://www.mathannotated.com/}{Peter Cao}, der das Feature vorschlug.}, mit denen die Elektronenübertragungen bei Redoxreaktionen angezeigt werden können. Beide Befehle verwenden `Ti\textbf{\textit{k}}Z', der zweite benötigt außerdem die Tikzlibrary `calc', \textbf{die daher in der Präambel geladen werden muss}.
+\begin{lstlisting}
+ \OX{<name>,<atom>}
+ \redox(<name1>,<name2>)[<tikz>][<dim>]{<text>}
+\end{lstlisting}
+Mit \lstinline=\OX= wird ein \lstinline=<atom>= in eine Node geschrieben, die den Namen \lstinline=<name>= bekommt. Hat man zwei \lstinline=\OX= gesetzt, können Sie mit \lstinline=\redox= mit einen Linie verbunden werden. Dazu werden die Namen der zu verbindenen Nodes in die Runden Klammern geschrieben. Da \lstinline=\redox= ein Tikzpicture mit den Optionen \lstinline=remember picture,overlay= zeichnet, muss das Dokument \emph{mindestens zweimal kompiliert} werden.
+\begin{lstlisting}
+ \OX{a,Na} $\rightarrow$ \OX{b,Na}\pch\redox(a,b){oxidation}
+\end{lstlisting}
+\OX{a,Na} $\rightarrow$ \OX{b,Na}\pch\redox(a,b){oxidation}
+
+Die Linie kann via \lstinline=<tikz>= mit Ti\textbf{\textit{k}}Z-Keys angepasst werden:
+\begin{lstlisting}
+ \begin{center}
+ \OX{a,Na} $\rightarrow$ \OX{b,Na}\pch\redox(a,b)[->,red]{ox}\redox(a,b)[<-,blue][-.6em]{red}
+ \end{center}
+\end{lstlisting}
+\begin{center}
+ \OX{a,Na} $\rightarrow$ \OX{b,Na}\pch\redox(a,b)[->,red]{ox}\redox(a,b)[<-,blue][-.6em]{red}
+\end{center}
+
+Mit \lstinline=<dim>= kann die Länge der vertikalen Linie festgelegt werden. Diese ist per Default \lstinline=.6em= lang. Gibt man hier einen negativen Wert an, wird die Linie \emph{unterhalb} des Textes geschrieben.
+\begin{lstlisting}
+ \OX{a,Na} $\rightarrow$ \OX{b,Na}\pch
+ \redox(a,b)[->]{ox}
+ \redox(a,b)[<-][-.6em]{red}
+\end{lstlisting}
+\OX{a,Na} $\rightarrow$ \OX{b,Na}\pch
+\redox(a,b)[->,red]{ox}
+\redox(a,b)[<-,blue][-.6em]{red}
+\vskip1cm
+Die Befehle funktionieren auch mit dem `mhchem'-Befehl \lstinline=\ce= und in Verbindung mit dem \lstinline=\ox=-Befehl (Abschnitt \ref{ssec:oxidationszahlen}).
+\begin{lstlisting}
+ \ce{ 2 \OX{o1,Na} + \OX{r1,Cl2} -> 2 \OX{o2,Na}\pch + 2 \OX{r2,Cl}\mch }
+ \redox(o1,o2){\small OX: $- 2\el$}

+\redox(o1,o2)[green,-stealth]{\small OX: $- 2\el$}
+\redox(r1,r2)[purple,-stealth][-.6em]{\small RED: $+ 2\el$}
+
+\section{(Standard) Zustand, Thermodynamik}\label{sec:standardstate}
+\subsection{Mit `siunitx'}\label{ssec:siunitx}
+Wenn das Paket `siunitx' geladen ist, stehen die folgenden Befehle zur Verfügung:
+\begin{itemize}
+ \item\lstinline=\Enthalpy[<kind>,<exponent>,<unit>]{<value>}=
+ \item\lstinline=\Entropy[<kind>,<exponent>,<unit>]{<value>}=
+ \item\lstinline=\Gibbs[<kind>,<exponent>,<unit>]{<value>}=
+\end{itemize}
+Ihr Einsatz ist eigentlich selbsterklärend: mit \lstinline=\Enthalpy{123}= wird \Enthalpy{123} gesetzt. Möchte man genauer spezifizieren, wofür die Enthalpie gelten soll, kann man das über das erste optionale Argument machen:\\
+\lstinline=\Enthalpy[r]{123}= \Enthalpy[r]{123}.
+
+Das Standardzustandssymbol kann durch das zweite optionale Argument ersetzt werden\ldots\\
+\lstinline=\Enthalpy[,0]{123}= \Enthalpy[,0]{123}\\
+\ldots und wird sowieso nur dann als Standardzustand gesetzt, wenn das Paket `chemstyle' geladen wurde, siehe Abschnitt \ref{ssec:state}.
+
+Mit dem dritten optionalen Argument schließlich kann die Einheit geändert werden:\\
+\lstinline=\Enthalpy[,kcal/mol]{123}= \Enthalpy[,,kcal/mol]{123}\\
+Die Einheit wird jeweils entsprechend der Regeln von `siunitx' gesetzt und hängt von den dort gewählten Otionen ab.
+\begin{lstlisting}
+ \Enthalpy{-1234.56e3}\par
+ \sisetup{per-mode=symbol,exponent-product=\cdot,output-decimal-marker={,},group-four-digits=true}
+ \Enthalpy{-1234.56e3}
+\end{lstlisting}
+{\Enthalpy{-1234.56e3}\par
+\sisetup{per-mode=symbol,exponent-product=\cdot,output-decimal-marker={,},group-four-digits=true}
+\Enthalpy{-1234.56e3}}
+
+Ganz entsprechendes gilt für
+\begin{lstlisting}
+ \Entropy{12.3}, \Gibbs{-12.3}.
+\end{lstlisting}
+\Entropy{12.3}, \Gibbs{-12.3}.
+
+Mit dem Befehl \lstinline=\setnewstate[<standard exponent>,<Delta symbol>]{<name>}{<symbol>}{<unit>}= können Sie auch neue entsprechende Befehle festlegen:
+\begin{lstlisting}
+ \setnewstate{Helmholtz}{A}{\kilo\joule\per\mole}
+ \setnewstate{ElPot}{E}{Volt}
+ \Helmholtz{123.4} \ElPot{-1.1}
+\end{lstlisting}
+{\setnewstate{Helmholtz}{A}{\kilo\joule\per\mole}\setnewstate{ElPot}{E}{Volt}\Helmholtz{123.4} \ElPot{-1.1}}
+
+Tatsächlich wurden
+\begin{lstlisting}
+ \Enthalpy, \Entropy, \Gibbs
+\end{lstlisting}
+über
+\begin{lstlisting}
+ \setnewstate{Enthalpy}{H}{\kilo\joule\per\mole}
+ \setnewstate[, ]{Entropy}{S}{\joule\per\kelvin\per\mole}
+ \setnewstate{Gibbs}{G}{\kilo\joule\per\mole}
+\end{lstlisting}
+definiert.
+
+Sie können mit \lstinline=\setnewstate= auch die vordefinierten Befehle überschreiben:
+\begin{lstlisting}
+ \setnewstate{Enthalpy}{X}{\joule\per\mole}
+ \Enthalpy[f]{12.5}
+\end{lstlisting}
+{\setnewstate{Enthalpy}{X}{\joule\per\mole}\Enthalpy[f]{12.5}}
+
+\subsection{State}\label{ssec:state}
+Die in Abschnitt \ref{ssec:siunitx} vorgestellten Befehle verwenden alle den auch ohne `siunitx' definierten Befehl
+\begin{lstlisting}
+ \State[<exponent>,<Delta symbol>]{<symbol>}{<kind>}
+\end{lstlisting}
+Mit diesem Befehl können die thermodynamischen Größen auch ohne Zahl und Einheit angegeben werden.
+\begin{lstlisting}
+ \State{G}{f}, \State[ ]{E}{}, \State[\SI{1000}{\celsius}]{H}{f}
+\end{lstlisting}
+\State{G}{f}, \State[ ]{E}{}, \State[\SI{1000}{\celsius}]{H}{f}
+
+Das Standardzustandssymbol wird nur angezeigt, wenn das Paket `chemstyle' geladen wurde und mit dem Befehl \lstinline=\standardstate= zur Verfügung steht. \lstinline=\State{A}{b}=: Wenn `chemstyle' geladen wurde \State{A}{b}, sonst \State[ ]{A}{b}.
+
+\section{Umgebungen für `mhchem'}\label{sec:mhchem}
+Falls das Paket `mhchem' geladen wurde, stehen die Umgebungen
+\begin{lstlisting}
+ \begin{reaction}
+ <mhchem code>
+ \end{reaction}
+ \begin{reactions}
+ <mhchem code>
+ \end{reactions}
+\end{lstlisting}
+sowie die Varianten
+\begin{lstlisting}
+ \begin{reaction*}
+ <mhchem code>
+ \end{reaction*}
+ \begin{reactions*}
+ <mhchem code>
+ \end{reactions*}
+\end{lstlisting}
+zur Verfügung. Die Umgebung \lstinline=reaction=/\lstinline=reaction*= verwendet die Mathematik-Um\-ge\-bung \lstinline=equation=/\lstinline=equation*=, die Umgebung \lstinline=reactions=/\lstinline=reactions*= die Mathematik-Umgebung \lstinline=align=/\lstinline=align*=, um die Reaktionen zu setzen.
+\begin{lstlisting}
+ Reaktion mit Zähler:
+ \begin{reaction}
+ H2 + 1/2 O2 -> H2O
+ \end{reaction}
+ Reaktion ohne Zähler:
+ \begin{reaction*}
+ C + O2 -> CO2
+ \end{reaction*}
+ mehrere Reaktionen mit Zähler:
+ \begin{reactions}
+ Cl2 &-> 2 Cl. \\
+ Cl.{} + CH4 &-> HCl + {}.CH3\\
+ {}{}.CH3 + Cl2 &-> CH3Cl + Cl.
+ \end{reactions}
+ mehrere Reaktionen ohne Zähler:
+ \begin{reactions*}
+ \Hpl + \Hyd &<=>> H2O\\
+ SO4 \mch[2] + Ba \pch[2] &-> BaSO4 v
+ \end{reactions*}
+\end{lstlisting}
+Reaktion mit Zähler:
+\begin{reaction}
+ H2 + 1/2 O2 -> H2O
+\end{reaction}
+Reaktion ohne Zähler:
+\begin{reaction*}
+ C + O2 -> CO2
+\end{reaction*}
+mehrere Reaktionen mit Zähler:
+\begin{reactions}
+ Cl2 &-> 2 Cl. \\
+ Cl.{} + CH4 &-> HCl + {}.CH3\\
+ {}{}.CH3 + Cl2 &-> CH3Cl + Cl.
+\end{reactions}
+mehrere Reaktionen ohne Zähler:
+\begin{reactions*}
+ \Hpl + \Hyd &<=>> H2O\\
+ SO4 \mch[2] + Ba \pch[2] &-> BaSO4 v
+\end{reactions*}
+Wenn Sie das Aussehen des Zählers ändern wollen, so können Sie \lstinline=\renewtagform{<tagname>}[<format>]{<right delim>}{<left delim>}=\footnote{Durch das Paket `mathtools' zur Verfügung gestellt} verwenden.
+\begin{lstlisting}
+ \renewtagform{CMreaction}[R \textbf]{[}{]}
+ \begin{reaction}
+ H2O + CO2 <<=> H2CO3
+ \end{reaction}
+\end{lstlisting}
+{\renewtagform{CMreaction}[R \textbf]{[}{]}
+\begin{reaction}
+ H2O + CO2 <<=> H2CO3
+\end{reaction}
+}
+
+\section{Newman-Projektionen}\label{sec:newman}
+Mit dem Befehl
+\begin{lstlisting}
+ \newman[<angle>,<scale>,<tikz>]{<1>,<2>,<3>,<4>,<5>,<6>}
+\end{lstlisting}
+lassen sich Newman-Projektionen erstellen (verwendet Ti\textbf{\textit{k}}Z). \textbf{Dazu müssen sie in der Präambel die Tikzlibrary `calc' einbinden}:
+\begin{lstlisting}
+ \usetikzlibrary{calc}
+\end{lstlisting}
+Beispiele:
+\begin{lstlisting}
+ \newman{}\par% Standard: gestaffelt
+ \newman[165]{}\par% gedreht => ekliptisch
+ \newman{1,2,3,4,5,6} \newman{1,2,3} \newman{,,,4,5,6}\par% mit Atomen
+ \newman[,.75,draw=blue,fill=blue!20]{}% verkleinert und mit TikZ angepasst
+\end{lstlisting}
+\newman{}\par
+\newman[165]{}\par
+\newman{1,2,3,4,5,6} \newman{1,2,3} \newman{,,,4,5,6}\par
+\newman[,.75,draw=blue,fill=blue!20]{}
+
+Mit einer weiteren Option können die Nodes der Atome gestaltet werden:
+\begin{lstlisting}
+ \newman[][<tikz nodes>]{<1>,<2>,<3>,<4>,<5>,<6>}
+ % Beispiel:
+ \newman[][draw=red,fill=red!20,inner sep=2pt,rounded corners]{1,2,3,4,5,6}
+\end{lstlisting}
+\newman[][draw=red,fill=red!20,inner sep=2pt,rounded corners]{1,2,3,4,5,6}
+
+Wenn Sie die "`vorderen"' und "`hinteren"' Nodes verschieden gestalten wollen, können Sie noch eine dritte Option verwenden:
+\begin{lstlisting}
+ \newman[][<tikz front nodes>][[<tikz back nodes>]]{<1>,<2>,<3>,<4>,<5>,<6>}
+ % Beispiel:
+ \newman[][draw=red,fill=red!20,inner sep=2pt,rounded corners][draw=blue,fill=blue!20,inner sep=2pt,rounded corners]{1,2,3,4,5,6} \newman[170][draw=red,fill=red!20,inner sep=2pt,rounded corners][draw=blue,fill=blue!20,inner sep=2pt,rounded corners]{1,2,3,4,5,6}
+\end{lstlisting}
+\newman[][draw=red,fill=red!20,inner sep=2pt,rounded corners][draw=blue,fill=blue!20,inner sep=2pt,rounded corners]{1,2,3,4,5,6} \newman[170][draw=red,fill=red!20,inner sep=2pt,rounded corners][draw=blue,fill=blue!20,inner sep=2pt,rounded corners]{1,2,3,4,5,6}
+
+\section{p-Orbitale}\label{sec:orbitale}
+\CMname\ stellt auch Befehle zur Verfügung, mit denen p-Orbitale visualisiert werden können.
+\begin{lstlisting}
+ \porb[<size factor>,<color>,<angle>]
+ \phorb[<size factor>,<color>,<angle>]
+ \setorbheight{<length>}
+\end{lstlisting}
+Damit wird ein liegendes oder um \lstinline=<angle>= gedrehtes p-Orbital dargestellt: \lstinline=\porb \qquad \porb[,,30]= \quad\porb \qquad\porb[,,30]
+
+\lstinline=\phorb= stellt nur ein halbes Orbital dar: \lstinline=\phorb[,red,90]= \phorb[,red,90]
+
+Mit den folgenden drei Befehlen stehen die in $x$-, $y$- und $z$-Richtung gedrehten Orbitale zusätzlich als Makro zur Verfügung:
+\begin{lstlisting}
+ \pzorb \qquad \pyorb \qquad \pxorb
+\end{lstlisting}
+\pzorb \qquad \pyorb \qquad \pxorb
+
+Durch geeignetes Verschieben lassen sie sich alle an einer Stelle darstellen:
+\begin{lstlisting}
+ \hspace{2cm}\pxorb\hspace{-.3em}\pyorb\hspace{-.3em}\pzorb
+ \tikz[overlay]{
+ \draw[->](0,0)--(1,0)node[right]{$y$};
+ \draw[dashed](0,0)--(-1,0);
+ \draw[->](0,0)--(0,1)node[above]{$z$};
+ \draw[dashed](0,0)--(0,-1);
+ \draw[->](0,0)--(-.707,-.707)node[below left]{$x$};
+ \draw[dashed](0,0)--(.707,.707);
+ }
+\end{lstlisting}
+\hspace{2cm}\pxorb\hspace{-.3em}\pyorb\hspace{-.3em}\pzorb\tikz[overlay]{\draw[->](0,0)--(1,0)node[right]{$y$};\draw[->](0,0)--(0,1)node[above]{$z$};\draw[->](0,0)--(-.707,-.707)node[below left]{$x$};\draw[dashed](0,0)--(-1,0);\draw[dashed](0,0)--(0,-1);\draw[dashed](0,0)--(.707,.707);}
+\vspace{2cm}
+
+Die Orbitale lassen sich z.\,B. auch zusammen mit `chemfig' einsetzen:
+\begin{lstlisting}
+ \setorbheight{2em}\setbondoffset{0pt}
+ \chemfig{?\pzorb-[,1.3]\pzorb-[:30,1.1]\pzorb-[:150,.9]\pzorb-[4,1.3]\pzorb-[:-150,1.1]\pzorb?}\qquad
+ \chemfig{?\pzorb-[,1.3]{\porb[,,-90]}-[:30,1.1]\pzorb-[:150,.9]{\porb[,,-90]}-[4,1.3]\pzorb-[:-150,1.1]{\porb[,,-90]}?}
+\end{lstlisting}
+\vspace{1cm}
+{\setorbheight{2em}\setbondoffset{0pt}
+\chemfig{?\pzorb-[,1.3]\pzorb-[:30,1.1]\pzorb-[:150,.9]\pzorb-[4,1.3]\pzorb-[:-150,1.1]\pzorb?}\qquad
+\chemfig{?\pzorb-[,1.3]{\porb[,,-90]}-[:30,1.1]\pzorb-[:150,.9]{\porb[,,-90]}-[4,1.3]\pzorb-[:-150,1.1]{\porb[,,-90]}?}}
+
+\section{Paket-Optionen}\label{sec:optionen}
+\CMname\ hat zwei Paketoptionen:
+\begin{itemize}
+ \item\lstinline+xspace=<boolean>+ Mit der Option \lstinline+xspace=true+ bekommen folgende Befehle ein \lstinline=\xspace= angehängt:\\
+ \lstinline=\Hyd \HtO Text \Hyd, \HtO, Text= \Hyd \HtO Text \Hyd, \HtO, Text\\
+ Default: \lstinline+xspace=false+
+ \item\lstinline+circled=<boolean>+ Nicht alle mögen Kreise um die Ladungssymbole ($\oplus$ und $\ominus$) sondern bevorzugen sie ohne Kreise ($+$ und $-$). Dieses Verhalten kann mit dieser Option gesteuert werden. Mit \lstinline+circled=false+ verwenden alle Befehle von \CMname\ die Symbole ohne Kreis.\\
+ Default: \lstinline+circled=true+
+\end{itemize}
+

+ \begin{abstract}
+ `\CMname' is a collection of macros and commands which are intended to make typesetting chemistry documents faster and more convenient. This includes some nomenclature commands, oxidation numbers, thermodynamic data, newman projections...

+
+\section{Licence, Requirements}
+\makeatletter\CM@name\ v\CM@version\makeatother\ underlies the The \LaTeX\ project public license\\(\url{http://www.latex-project.org/lppl.txt}).
+
+\CMname\ internally loads the packages \paket{xkeyval}, \paket{amsmath} and `tikz' (Ti\textbf{\textit{k}}Z = \paket{pgf}). If they're missing it will cause an error.
+
+The definition of some commands depends on which packages have been loaded \emph{before} \CMname\ was loaded. Some commands are only defined if a certain package has been loaded. This concern the packages \paket{mhchem}, \paket{siunitx} and \paket{chemstyle} and the commands from section \ref{sec:teilchen}, \lstinline=\ox= (section \ref{ssec:oxidationszahlen}), the commands from section \ref{sec:standardstate} and the environments drom section \ref{sec:mhchem}.
+
+The package option \lstinline=xspace= (section \ref{sec:optionen}) needs the package \paket{xspace} to be available.
+
+If the user loads `mhchem' \emph{before} \CMname, the packages \paket{mathtools} and \paket{environ} are needed.
+
+The \lstinline=\redox= command (section \ref{sec:redoxreaktionen}) and the \lstinline=\newman= command (section \ref{sec:newman} need the tikz library `calc' to be loaded.
+
+The full functionality should be guaranteed with a preamble like this:
+\begin{lstlisting}
+ \usepackage{siunitx,chemstyle}
+ \usepackage[version=3,arrows=pgf]{mhchem}
+ \usepackage[xspace=true]{chemmacros}
+ \usetikzlibrary{calc}
+\end{lstlisting}
+
+\section{Particles, Ions and a Symbol}\label{sec:teilchen}
+Some simple macros for displaying often needed particles and a symbol:
+\begin{itemize}
+ \item\lstinline=\Hpl= \Hpl (proton)
+ \item\lstinline=\Hyd= \Hyd (hydroxide)
+ \item\lstinline=\HtO= \HtO (oxonium)
+ \item\lstinline=\el= \el (electron)
+ \item\lstinline=\prt= \prt (proton)
+ \item\lstinline=\ntr= \ntr (neutron)
+ \item\lstinline=\transitionstatesymbol= \transitionstatesymbol\ transition state symbol (uses Ti\textbf{\textit{k}}Z)
+\end{itemize}
+These commands are working both in text mode and math mode. Depending on wether `mhchem' has been loaded, the first three particles are defined with the \lstinline=\cf{}= command or with \lstinline=\ensuremath{\text{}}=.
+
+\section{Stereo Descriptors, Nomenclature}\label{sec:stereo}
+The following macros are intended to make the writing of IUPAC names more convenient:
+\begin{itemize}
+ \item Cahn-Ingold-Prelog:
+ \begin{itemize}
+ \item\lstinline=\Rcip= \Rcip
+ \item\lstinline=\Scip= \Scip
+ \item\lstinline=\cip{<conf>}= e.\,g.: \lstinline=\cip{R,S}= \cip{R,S}
+ \end{itemize}
+ \item Fischer:
+ \begin{itemize}
+ \item\lstinline=\Dfi= \Dfi
+ \item\lstinline=\Lfi= \Lfi
+ \end{itemize}
+ \item cis/trans \&\ zusammen/entgegen:
+ \begin{itemize}
+ \item\lstinline=\Z= \Z
+ \item\lstinline=\E= \E
+ \item\lstinline=\cis= \cis
+ \item\lstinline=\trans= \trans
+ \end{itemize}
+ \item ortho/meta/para:
+ \begin{itemize}
+ \item\lstinline=\ortho= \ortho
+ \item\lstinline=\meta= \meta
+ \item\lstinline=\para= \para
+ \end{itemize}
+\end{itemize}
+absolute configuration (uses Ti\textbf{\textit{k}}Z):
+\begin{itemize}
+ \item\lstinline=\Rconf[<letter>]= \lstinline=\Rconf=: \Rconf \quad\lstinline=\Rconf[]=: \Rconf[]
+ \item\lstinline=\Sconf[<letter>]= \lstinline=\Sconf=: \Sconf \quad\lstinline=\Sconf[]=: \Sconf[]
+\end{itemize}
+
+\begin{lstlisting}
+ \Dfi-Weinsäure = \cip{2S,3S}-Weinsäure, \Dfi-($-$)-Threose = \cip{2S,3R}-($-$)-2,3,4-Trihydroxybutanal\\
+ \cis-2-Buten = \Z-2-Butene, \cip{2E,4Z}-Hexadiene\\
+ \meta-Xylol = 1,3-Dimethylbenzene
+
+ % with `bpchem' command \IUPAC:
+ \IUPAC{\Dfi-Wein\|säure} = \IUPAC{\cip{2S,3S}-Wein\|säure}, \IUPAC{\Dfi-($-$)-Threose} = \IUPAC{\cip{2S,3R}-($-$)-2,3,4\-Tri\|hydroxy\|butanal}
+\end{lstlisting}
+\Dfi-Weinsäure = \cip{2S,3S}-Weinsäure, \Dfi-($-$)-Threose = \cip{2S,3R}-($-$)-2,3,4-Trihydroxybutanal\\
+\cis-2-Buten = \Z-2-Butene, \cip{2E,4Z}-Hexadiene\\
+\meta-Xylol = 1,3-Dimethylbenzene
+
+\IUPAC{\Dfi-Wein\|säure} = \IUPAC{\cip{2S,3S}-Wein\|säure}, \IUPAC{\Dfi-($-$)-Threose} = \IUPAC{\cip{2S,3R}-($-$)-2,3,4\-Tri\|hydroxy\|butanal}
+
+The last example uses the \lstinline=\IUPAC= command, which is provided by the \paket{bpchem} package.
+
+\section{Oxidation Numbers and (real) Charges}\label{sec:ladungen}
+\subsection{Ion Charges}\label{ssec:ionen}
+Simple displaying of charges:
+\begin{itemize}
+ \item\lstinline=\pch[<number>]= positive charge (\textbf{p}lus + \textbf{ch}arge), \lstinline=\pch, Na\pch, Ca\pch[2]= \pch, Na\pch, Ca\pch[2]
+ \item\lstinline=\mch[<number>]= negative charge (\textbf{m}inus + \textbf{ch}arge), \lstinline=\mch, F\mch, S\mch[2]= \mch, F\mch, S\mch[2]
+\end{itemize}
+
+\subsection{Oxidation Numbers}\label{ssec:oxidationszahlen}
+Typesetting oxidation numbers:
+\begin{itemize}
+ \item\lstinline=\ox{<number>,<atom>}= places \lstinline=<number>= above \lstinline=<atom>=; \lstinline=\ox{+1,Na}=, \lstinline=\ox{+I,Na}=, \lstinline=\ox{-2,S}=, \lstinline=\ox{-II,S}= \ox{+1,Na}, \ox{+I,Na}, \ox{-2,S}, \ox{-II,S}
+\end{itemize}
+If the package `mhchem' has been loaded \lstinline=<atom>= is set inside the \lstinline=\ce= command: \lstinline=\ox{+II,Ca}\ox{-I,F2}= \ox{+II,Ca}\ox{-I,F2}. Without `mhchem' this isn't working this way {\makeatletter\def\oxNoMhchem#1#2{\ensuremath{\overset{\text{\tiny\CM@ox@sign#1}}{\text{#2}}}}\makeatother(\oxNoMhchem{+II}{Ca}\oxNoMhchem{-I}{F2}) and you need to use the math way: \lstinline=\ox{+II,Ca}\ox{-I,F$_2$}= \oxNoMhchem{+II}{Ca}\oxNoMhchem{-I}{F$_2$}}.
+
+\subsection{Partial Charges and similar Stuff}\label{ssec:partialladungen}
+The next ones probably are seldomly needed but nevertheless useful:
+\begin{itemize}
+ \item\lstinline=\delp= \delp (\textbf{del}ta + \textbf{p}lus)
+ \item\lstinline=\delm= \delm (\textbf{del}ta + \textbf{m}inus)
+\end{itemize}
+These macros for example can be used with the \lstinline=\ox= command or with the \paket{chemfig} package:
+\begin{lstlisting}
+ \ox{\delp,H}\ox{\delm,Cl}\par
+ \chemfig{\chemabove[3pt]{\lewis{246,Br}}{\delm}-\chemabove[3pt]{H}{\delp}}
+\end{lstlisting}
+\ox{\delp,H}\ox{\delm,Cl}\par
+\chemfig{\chemabove[3pt]{\lewis{246,Br}}{\delm}-\chemabove[3pt]{H}{\delp}}
+
+Also the following macros are useful together with `chemfig'.
+\begin{itemize}
+ \item\lstinline=\scrp= \scrp (\textbf{scr}iptstyle + \textbf{p}lus)
+ \item\lstinline=\scrm= \scrm (\textbf{scr}iptstyle + \textbf{m}inus)
+\end{itemize}
+For example:
+\begin{lstlisting}
+ {\setatomsep{1.8em}\chemfig{CH_3-CH_2-\chemabove{\lewis{026,O}}{\hspace{5mm}\scrm}}}
+\end{lstlisting}

+\section{Redox Reactions}\label{sec:redoxreaktionen}
+\CMname\ provides two commands \footnote{Thanks to \href{http://www.mathannotated.com/}{Peter Cao} who suggested the feature.} to visualize the transfer of electrons in redox reactions. Both commands are using `Ti\textbf{\textit{k}}Z', the second also needs the tikz library `calc', \textbf{which thus must be loaded in the preamble}.
+\begin{lstlisting}
+ \OX{<name>,<atom>}
+ \redox(<name1>,<name2>)[<tikz>][<dim>]{<text>}
+\end{lstlisting}
+\lstinline=\OX= places \lstinline=<atom>= into a node, which is named with \lstinline=<name>=. If you have set two\lstinline=\OX=, they can be connected with a line using \lstinline=\redox=. To do so the names of the two nodes that shall be connected are written in the round braces. Since \lstinline=\redox= draw a tikzpicture with options \lstinline=remember picture,overlay=, the document needs to be \emph{compiled at least two times}.
+\begin{lstlisting}
+ \OX{a,Na} $\rightarrow$ \OX{b,Na}\pch\redox(a,b){oxidation}
+\end{lstlisting}
+\OX{a,Na} $\rightarrow$ \OX{b,Na}\pch\redox(a,b){oxidation}
+
+This line can be customized using Ti\textbf{\textit{k}}Z keys in \lstinline=<tikz>=:
+\begin{lstlisting}
+ \OX{a,Na} $\rightarrow$ \OX{b,Na}\pch\redox(a,b)[->,red]{ox}
+\end{lstlisting}
+\OX{a,Na} $\rightarrow$ \OX{b,Na}\pch\redox(a,b)[->,red]{ox}
+
+\lstinline=<dim>= can be used to adjust the length of the vertical line. The default value is \lstinline=.6em=. If you use a negative value the line is placed \emph{below} the text.
+\begin{lstlisting}
+ \begin{center}
+ \OX{a,Na} $\rightarrow$ \OX{b,Na}\pch\redox(a,b)[->,red]{ox}\redox(a,b)[<-,blue][-.6em]{red}
+ \end{center}
+\end{lstlisting}
+\begin{center}
+ \OX{a,Na} $\rightarrow$ \OX{b,Na}\pch\redox(a,b)[->,red]{ox}\redox(a,b)[<-,blue][-.6em]{red}
+\end{center}
+
+Both commands also can be used with the `mhchem' command \lstinline=\ce= and with the \lstinline=\ox= command (section \ref{ssec:oxidationszahlen}).
+\begin{lstlisting}

+\section{(Standard) State, Thermodynamics}\label{sec:standardstate}
+\subsection{With `siunitx'}\label{ssec:siunitx}
+If the package `siunitx' has been loaded, the following commands are available:
+\begin{itemize}
+ \item\lstinline=\Enthalpy[<kind>,<exponent>,<unit>]{<value>}=
+ \item\lstinline=\Entropy[<kind>,<exponent>,<unit>]{<value>}=
+ \item\lstinline=\Gibbs[<kind>,<exponent>,<unit>]{<value>}=
+\end{itemize}
+Their usage is pretty much self-explaining: \lstinline=\Enthalpy{-123.4}= gives \Enthalpy{-123.4}. If you want to specify what kind of enthalpy (reaction, formation,\ldots) is meant Möchte you can use the first optional argument:\\
+\lstinline=\Enthalpy[r]{-123.4}= \Enthalpy[r]{-123.4}.
+
+The standard state symbol can be replaced by the second optional argument\ldots\\
+\lstinline=\Enthalpy[,o]{-123.4}= \Enthalpy[,o]{-123.4}\\
+\ldots and is anyway only set as standard state if the package `chemstyle' has been loaded, see section \ref{ssec:state}.
+
+The third optional argument can be used to change the unit:\\
+\lstinline=\Enthalpy[,kcal/mol]{-123.4}= \Enthalpy[,,kcal/mol]{-123.4}\\
+The unit is set corresponding to the rules of `siunitx' and depends on its settings:
+\begin{lstlisting}
+ \Enthalpy{-1234.56e3}\par
+ \sisetup{per-mode=symbol,exponent-product=\cdot,output-decimal-marker={,},group-four-digits=true}
+ \Enthalpy{-1234.56e3}
+\end{lstlisting}
+{\Enthalpy{-1234.56e3}\par
+\sisetup{per-mode=symbol,exponent-product=\cdot,output-decimal-marker={,},group-four-digits=true}
+\Enthalpy{-1234.56e3}}
+
+The other two commands work exactly the same way.
+\begin{lstlisting}
+ \Entropy{12.3}, \Gibbs{-12.3}.
+\end{lstlisting}
+\Entropy{12.3}, \Gibbs{-12.3}.
+
+You can use the command \lstinline=\setnewstate[<standard exponent>,<Delta symbol>]{<name>}{<symbol>}{<unit>}= to create new corresponding commands:
+\begin{lstlisting}
+ \setnewstate{Helmholtz}{A}{\kilo\joule\per\mole}
+ \setnewstate{ElPot}{E}{Volt}
+ \Helmholtz{123.4} \ElPot{-1.1}
+\end{lstlisting}
+{\setnewstate{Helmholtz}{A}{\kilo\joule\per\mole}\setnewstate{ElPot}{E}{Volt}\Helmholtz{123.4} \ElPot{-1.1}}
+
+Indeed, the commands
+\begin{lstlisting}
+ \Enthalpy, \Entropy, \Gibbs
+\end{lstlisting}
+are defined as follows:
+\begin{lstlisting}
+ \setnewstate{Enthalpy}{H}{\kilo\joule\per\mole}
+ \setnewstate[, ]{Entropy}{S}{\joule\per\kelvin\per\mole}
+ \setnewstate{Gibbs}{G}{\kilo\joule\per\mole}
+\end{lstlisting}
+
+With \lstinline=\setnewstate= you also can redefine the existing commands:
+\begin{lstlisting}
+ \setnewstate{Enthalpy}{X}{\joule\per\mole}
+ \Enthalpy[f]{12.5}
+\end{lstlisting}
+{\setnewstate{Enthalpy}{X}{\joule\per\mole}\Enthalpy[f]{12.5}}
+
+\subsection{State}\label{ssec:state}
+The commands presented in section \ref{ssec:siunitx} internally all use the command
+\begin{lstlisting}
+ \State[<exponent>,<Delta symbol>]{<symbol>}{<kind>}
+\end{lstlisting}
+which also is available without `siunitx'. It can be used to write the thermodynamic variables without value and unit.
+\begin{lstlisting}
+ \State{G}{f}, \State[ ]{E}{}, \State[\SI{1000}{\celsius}]{H}{f}, \State[ ,\delta]{+}{}
+\end{lstlisting}
+\State{G}{f}, \State[ ]{E}{}, \State[\SI{1000}{\celsius}]{H}{f}, \State[ ,\delta]{+}{}
+
+The standard state symbol \standardstate\ is only used, if the `chemstyle' package has been loaded, which provides it through the command \lstinline=\standardstate=. With `chemstyle': \lstinline=\State{A}{b}= \State{A}{b}, without: \State[ ]{A}{b}.
+
+\section{Environments for `mhchem'}\label{sec:mhchem}
+If the package `mhchem' has been loaded the environments
+\begin{lstlisting}
+ \begin{reaction}
+ <mhchem code>
+ \end{reaction}
+ \begin{reactions}
+ <mhchem code>
+ \end{reactions}
+\end{lstlisting}
+and the starred versions
+\begin{lstlisting}
+ \begin{reaction*}
+ <mhchem code>
+ \end{reaction*}
+ \begin{reactions*}
+ <mhchem code>
+ \end{reactions*}
+\end{lstlisting}
+are defined. \lstinline=reaction=/\lstinline=reaction*= uses the math environment \lstinline=equation=/\lstinline=equation*= and \lstinline=reactions=/\lstinline=reactions*= uses the math environment \lstinline=align=/\lstinline=align*= to display the reactions.
+\begin{lstlisting}
+ reaction with counter:
+ \begin{reaction}
+ H2 + 1/2 O2 -> H2O
+ \end{reaction}
+ reaction without counter:
+ \begin{reaction*}
+ C + O2 -> CO2
+ \end{reaction*}
+ several aligned reactions with counter:
+ \begin{reactions}
+ Cl2 &-> 2 Cl. \\
+ Cl.{} + CH4 &-> HCl + {}.CH3\\
+ {}{}.CH3 + Cl2 &-> CH3Cl + Cl.
+ \end{reactions}
+ several aligned reactions without counter:
+ \begin{reactions*}
+ \Hpl + \Hyd &<=>> H2O\\
+ SO4 \mch[2] + Ba \pch[2] &-> BaSO4 v
+ \end{reactions*}
+\end{lstlisting}
+reaction with counter:
+\begin{reaction}
+ H2 + 1/2 O2 -> H2O
+\end{reaction}
+reaction without counter:
+\begin{reaction*}
+ C + O2 -> CO2
+\end{reaction*}
+several aligned reactions with counter:
+\begin{reactions}
+ Cl2 &-> 2 Cl. \\
+ Cl.{} + CH4 &-> HCl + {}.CH3\\
+ {}{}.CH3 + Cl2 &-> CH3Cl + Cl.
+\end{reactions}
+several aligned reactions without counter:
+\begin{reactions*}
+ \Hpl + \Hyd &<=>> H2O\\
+ SO4 \mch[2] + Ba \pch[2] &-> BaSO4 v
+\end{reactions*}
+If you want to change the layout of the counter tags, you can use \lstinline=\renewtagform{<tagname>}[<format>]{<right delim>}{<left delim>}=\footnote{provided by the package `mathtools'}.
+\begin{lstlisting}
+ \renewtagform{CMreaction}[R \textbf]{[}{]}
+ \begin{reaction}
+ H2O + CO2 <<=> H2CO3
+ \end{reaction}
+\end{lstlisting}
+{\renewtagform{CMreaction}[R \textbf]{[}{]}
+\begin{reaction}
+ H2O + CO2 <<=> H2CO3
+\end{reaction}
+}
+
+\section{Newman Projections}\label{sec:newman}
+The command
+\begin{lstlisting}
+ \newman[<angle>,<scale>,<tikz>]{<1>,<2>,<3>,<4>,<5>,<6>}
+\end{lstlisting}
+allows you to create newman projections (uses Ti\textbf{\textit{k}}Z). \textbf{You need to load the tikz library `calc' for that}:
+\begin{lstlisting}
+ \usetikzlibrary{calc}
+\end{lstlisting}
+Examples:
+\begin{lstlisting}
+ \newman{}\par% default: staggered
+ \newman[165]{}\par% rotated by 165 degrees => eclipsed
+ \newman{1,2,3,4,5,6} \newman{1,2,3} \newman{,,,4,5,6}\par% with atoms
+ \newman[,.75,draw=blue,fill=blue!20]{}% scaled and customized with TikZ
+\end{lstlisting}
+\newman{}\par
+\newman[165]{}\par
+\newman{1,2,3,4,5,6} \newman{1,2,3} \newman{,,,4,5,6}\par
+\newman[,.75,draw=blue,fill=blue!20]{}
+
+Another option allows you to customize the nodes within which the atoms are placed:
+\begin{lstlisting}
+ \newman[][<tikz nodes>]{<1>,<2>,<3>,<4>,<5>,<6>}
+ % example:
+ \newman[][draw=red,fill=red!20,inner sep=2pt,rounded corners]{1,2,3,4,5,6}
+\end{lstlisting}
+\newman[][draw=red,fill=red!20,inner sep=2pt,rounded corners]{1,2,3,4,5,6}
+
+If you want to display the "front" atoms differently from the "back" atoms, you can use a third option:
+\begin{lstlisting}
+ \newman[][<tikz front nodes>][[<tikz back nodes>]]{<1>,<2>,<3>,<4>,<5>,<6>}
+ % example:
+ \newman[][draw=red,fill=red!20,inner sep=2pt,rounded corners][draw=blue,fill=blue!20,inner sep=2pt,rounded corners]{1,2,3,4,5,6} \newman[170][draw=red,fill=red!20,inner sep=2pt,rounded corners][draw=blue,fill=blue!20,inner sep=2pt,rounded corners]{1,2,3,4,5,6}
+\end{lstlisting}
+\newman[][draw=red,fill=red!20,inner sep=2pt,rounded corners][draw=blue,fill=blue!20,inner sep=2pt,rounded corners]{1,2,3,4,5,6} \newman[170][draw=red,fill=red!20,inner sep=2pt,rounded corners][draw=blue,fill=blue!20,inner sep=2pt,rounded corners]{1,2,3,4,5,6}
+
+\section{p-Orbitals}\label{sec:orbitale}
+\CMname\ provides commands to visualize p-orbitals.
+\begin{lstlisting}
+ \porb[<size factor>,<color>,<angle>]
+ \phorb[<size factor>,<color>,<angle>]
+ \setorbheight{<length>}
+\end{lstlisting}
+This displays a horizontal orbital or one rotated by \lstinline=<angle>=: \lstinline=\porb \qquad \porb[,,30]= \quad\porb \qquad\porb[,,30]
+
+\lstinline=\phorb= only displays one half orbital: \lstinline=\phorb[,red,90]= \phorb[,red,90]
+
+There are shortcuts for the $x$-, $y$- and $z$-orbitals:
+\begin{lstlisting}
+ \pzorb \qquad \pyorb \qquad \pxorb
+\end{lstlisting}
+\pzorb \qquad \pyorb \qquad \pxorb
+
+With suitable shifting you can display them all on one spot:
+\begin{lstlisting}
+ \hspace{2cm}\pxorb\hspace{-.3em}\pyorb\hspace{-.3em}\pzorb
+ \tikz[overlay]{
+ \draw[->](0,0)--(1,0)node[right]{$y$};
+ \draw[dashed](0,0)--(-1,0);
+ \draw[->](0,0)--(0,1)node[above]{$z$};
+ \draw[dashed](0,0)--(0,-1);
+ \draw[->](0,0)--(-.707,-.707)node[below left]{$x$};
+ \draw[dashed](0,0)--(.707,.707);
+ }
+\end{lstlisting}
+\hspace{2cm}\pxorb\hspace{-.3em}\pyorb\hspace{-.3em}\pzorb\tikz[overlay]{\draw[->](0,0)--(1,0)node[right]{$y$};\draw[->](0,0)--(0,1)node[above]{$z$};\draw[->](0,0)--(-.707,-.707)node[below left]{$x$};\draw[dashed](0,0)--(-1,0);\draw[dashed](0,0)--(0,-1);\draw[dashed](0,0)--(.707,.707);}
+\vspace{2cm}
+
+The orbitals also can be used together with `chemfig':
+\begin{lstlisting}
+ \setorbheight{2em}\setbondoffset{0pt}
+ \chemfig{?\pzorb-[,1.3]\pzorb-[:30,1.1]\pzorb-[:150,.9]\pzorb-[4,1.3]\pzorb-[:-150,1.1]\pzorb?}\qquad
+ \chemfig{?\pzorb-[,1.3]{\porb[,,-90]}-[:30,1.1]\pzorb-[:150,.9]{\porb[,,-90]}-[4,1.3]\pzorb-[:-150,1.1]{\porb[,,-90]}?}
+\end{lstlisting}
+\vspace{1cm}
+{\setorbheight{2em}\setbondoffset{0pt}
+\chemfig{?\pzorb-[,1.3]\pzorb-[:30,1.1]\pzorb-[:150,.9]\pzorb-[4,1.3]\pzorb-[:-150,1.1]\pzorb?}\qquad
+\chemfig{?\pzorb-[,1.3]{\porb[,,-90]}-[:30,1.1]\pzorb-[:150,.9]{\porb[,,-90]}-[4,1.3]\pzorb-[:-150,1.1]{\porb[,,-90]}?}}
+
+\section{Pachage Options}\label{sec:optionen}
+\CMname\ has two package options:
+\begin{itemize}
+ \item\lstinline+xspace=<boolean>+ With the option \lstinline+xspace=true+ the commands\\
+ \lstinline=\Hyd \HtO Text \Hyd, \HtO, Text= \Hyd \HtO Text \Hyd, \HtO, Text\\
+ get a \lstinline=\xspace=.\\
+ Default: \lstinline+xspace=false+
+ \item\lstinline+circled=<boolean>+ not everybody likes circled charge symbols ($\oplus$ and $\ominus$). Some prefer them without circles ($+$ and $-$). This can be chosen this option. With \lstinline+circled=false+ all \CMname\ commands are set without circles.\\
+ Default: \lstinline+circled=true+
+\end{itemize}
