The settings now are done completely with a key/value system. This way there are now much more possibilities to customize commands. This also means that the syntax of a number of commands has changed\changed{command}. In order to provide compatibility with documents set with v1.*, there is now the package option \code{version=1}, which restores the old definitions.

Some also can be used without value (\cmd{usepackage\oa{option1, option2}\ma{chemmacros}}), which means that the \uline{underlined} value is used. \begin{description} - \item[\texttt{bpchem}] With this option first the package `bpchem' is loaded and second the appearance of the \lstinline=\NMR= command is changed to match the `bpchem' commands \lstinline=\HNMR= and \lstinline=\CNMR=. Without option: \NMR; with option: \HNMR; - \item[\texttt{circled}] Some chemists -- like me -- prefer circled charge symbols to have a clear distinction between charge and math symbols. In `\CMname's default behaviour they're \emph{not} circled ($+$ und $-$). With the option \lstinline+circled+ all commands of `\CMname' use the circled ones ($\oplus$ und $\ominus$). - \item[\texttt{german}] This option changes \lstinline=\pKa= from \mbox{\textsl{p}$K_\mathrm{A}$} into \mbox{\textsl{p}$K_\mathrm{S}$}. Also the phase identifiers \lstinline=\solid= and \lstinline=\liquid= are changed from \solid\ and \liquid\ into \solid[f] and \liquid[f\/l]. - \item[\texttt{xspace}] With this option, the following commands get a \lstinline=\xspace=: \lstinline=\Hpl= \lstinline=\HtO= \lstinline=\water= \lstinline=\Hyd= \lstinline=\HtO= \lstinline=\pH= \lstinline=\pOH= \lstinline=\pKa= \lstinline=\pKb= \lstinline=\cis= \lstinline=\trans= \lstinline=\insitu= \lstinline=\abinitio= \lstinline=\mech= \lstinline=\NMR= \Hpl \HtO \water \Hyd \HtO \pH \pOH \pKa \pKb \cis \trans \insitu \abinitio \mech \NMR\\ - The two commands \lstinline=\cis= and \lstinline=\trans= are also defined by the `bpchem' package. If you load that package, they are redefined by `\CMname'. In the definition of `bpchem' they \textit{always} have a \lstinline=\xspace=, with `\CMname' only with option \lstinline=xspace=. Apart from that they're identical. + \item[\code{bpchem = \uline{true}/false>}] This option loads the package \paket{bpchem} and adjusts the layout of the \cmd{NMR} command to the \paket{bpchem} commands \cmd{HNMR} and \cmd{CNMR}. (default: \code{false})\label{key:option_bpchem} + % + \item[\code{circled = \uline{formal}/all/none}] \CMname uses two different kinds of charges\footnote{Thanks to Christoph Sch\"afer, who pointed out to me, that v1.1 handled the charges too undifferentiated!}, which indicate the usage of real ($+/-$ ) and formal (\fplus/\fminus) charges. The option \code{formal} distinguishes between them, option \code{none} displays them all without circle, option \code{all} circles all (default: \code{formal}).\label{key:option_circled} + % + \item[\code{circletype = \uline{chem}/math}] This option switches between two kinds of circled charge symbols: \cmd{fplus} \fplus\ and \code{\$\cmd{oplus}\$} $\oplus$. (Default: \code{chem})\label{key:option_circletype} + % + \item[\code{EZ = \uline{chemmacros}/cool}] The command \cmd{E} is defined by the package \paket{cool} as well as by \CMname.

Often you have to leave blank spaces: -\begin{lstlisting} +\begin{LTXexample} \ce{Na\pch}\\ % no problem \ce{Ca\pch[2]}\\ % displayed wrong \ce{Ca \pch[2]}\\ % displayed right \ce{Ca$\pch[2]$} % displayed right -\end{lstlisting} -\ce{Na\pch}\\ -\ce{Ca\pch[2]}\\ -\ce{Ca \pch[2]}\\ -\ce{Ca$\pch[2]$} +\end{LTXexample} You also need to put curly braces at the end of commands: -\begin{lstlisting} +\begin{LTXexample} \ce{\mch OMe}\\ % displayed wrong \ce{\mch{} OMe}\\ % displayed right \ce{$\mch$OMe} % displayed right -\end{lstlisting} -\ce{\mch OMe}\\ -\ce{\mch{} OMe}\\ -\ce{$\mch$OMe} +\end{LTXexample} -This is \emph{not} only true for `\CMname' commands! -\begin{lstlisting} +This is \emph{not} only true for \CMname commands! +\begin{LTXexample}[pos=b] \ce{A \quad B} \ce{Na2\textbf{O}}\\ % displayed wrong \ce{A \quad{} B} \ce{Na2 \textbf{O}}\\ % displayed right \ce{A $\quad$ B} \ce{Na2 \textbf{O}} % displayed right -\end{lstlisting} -\ce{A \quad B} \ce{Na2\textbf{O}}\\ -\ce{A \quad{} B} \ce{Na2 \textbf{O}}\\ -\ce{A $\quad$ B} \ce{Na2 \textbf{O}} +\end{LTXexample} -As you can see in most cases instead of using blank spaces or curly braces you can also put the according command between \lstinline=$ $=. +As you can see in most cases instead of using blank spaces or curly braces you can also put the according command between \code{\$ \$}. \subsection{Reaction Environments}\label{ssec:mhchem_reaktionen} -\subsubsection{Defined by `\CMname'} +\subsubsection{Defined by \CMname} You can use these environments for numbered\ldots -\begin{lstlisting} - \begin{reaction} - <mhchem code> - \end{reaction} - \begin{reactions} - <mhchem code> - \end{reactions} -\end{lstlisting} +\begin{framed} +\cmd{begin\ma{reaction}}\\ + \code{<mhchem code>}\\ +\cmd{end\ma{reaction}}\\ +\cmd{begin\ma{reactions}}\\ + \code{<mhchem code>}\\ +\cmd{end\ma{reactions}} +\end{framed} \ldots and their starred versions for unnumbered reactions. -\begin{lstlisting} - \begin{reaction*} - <mhchem code> - \end{reaction*} - \begin{reactions*} - <mhchem code> - \end{reactions*} -\end{lstlisting} +\begin{framed} +\cmd{begin\ma{reaction*}}\\ + \code{<mhchem code>}\\ +\cmd{end\ma{reaction*}}\\ +\cmd{begin\ma{reactions*}}\\ + \code{<mhchem code>}\\ +\cmd{end\ma{reactions*}} +\end{framed} With them you can create (un)numbered reaction equations similar to mathematical equations. -The environments \verb=reaction=/\verb=reaction*= use the \lstinline=equation=/\lstinline=equation*= environments and the environments \verb=reactions=/\verb=reactions*= use the \lstinline=align=/\lstinline=align*= environments to display the reactions. +The environments \code{reaction}/\code{reaction*} use the \code{equation}/\code{equation*} environments and the environments \code{reactions}/ \code{reactions*} use the \code{align}/\code{align*} environments to display the reactions. -Reaction with counter: -\begin{lstlisting} +\begin{LTXexample}[pos=b] + Reaction with counter: \begin{reaction} A -> B \end{reaction} -\end{lstlisting} -\begin{reaction} - A -> B -\end{reaction} -Reaction without counter: -\begin{lstlisting} +\end{LTXexample} + +\begin{LTXexample}[pos=b] + Reaction without counter: \begin{reaction*} C -> D \end{reaction*} -\end{lstlisting} -\begin{reaction*} - C -> D -\end{reaction*} -Several aligned reactions with counter: -\begin{lstlisting} +\end{LTXexample} + +\begin{LTXexample}[pos=b] + Several aligned reactions with counter: \begin{reactions} A &-> B + C \\ D + E &-> F \end{reactions} -\end{lstlisting} -\begin{reactions} - A &-> B + C \\ - D + E &-> F -\end{reactions} -Several aligned reactions without counter: -\begin{lstlisting} +\end{LTXexample} + +\begin{LTXexample}[pos=b] + Several aligned reactions without counter: \begin{reactions*} G &-> H + I \\ J + K &-> L \end{reactions*} -\end{lstlisting} -\begin{reactions*} - G &-> H + I \\ - J + K &-> L -\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 `mathtools' package.}. -\begin{lstlisting} - \renewtagform{CMreaction}[R \textbf]{[}{]} +\end{LTXexample} + +If you want to change the layout of the counter tags, you can use \cmd{renewtagform\ma{<tagname>}\oa{<format>}\ma{<right delim>}\ma{<left delim>}}\footnote{Provided by the \paket{mathtools} package}. +\begin{LTXexample}[pos=b] + \renewtagform{reaction}[R \textbf]{[}{]} \begin{reaction} H2O + CO2 <<=> H2CO3 \end{reaction} -\end{lstlisting} -{\renewtagform{CMreaction}[R \textbf]{[}{]} -\begin{reaction} - H2O + CO2 <<=> H2CO3 -\end{reaction} -} +\end{LTXexample} +Note, that the name of the tagform has changed with v2.0. It was called \code{CMreaction} in v1.*. Option \code{version=1} restores this name. \subsubsection{Own Reactions} -\NEU[1.1]You can create new types of reactions with the command: -\begin{lstlisting} - \newreaction{<name>}{<math name>} -\end{lstlisting} -\lstinline=<name>= will be the name of the new environment. \lstinline=<math name>= is the used math environment. - -The command has variants. The first one is \lstinline=\newreaction*=, which will also define a starred version of the new environment, if the starred math environment exists. If it doesn't exist, this will cause an error. - -The second one is \lstinline=\newreaction+=, which is used to define an environment with a mandatory argument. Of course this only works, if the used math environment has a mandatory argument. - -You can also use the combined version \lstinline=\newreaction*+=. - -The predefined environments are defined via -\begin{lstlisting} - \newreaction*{++reaction++}{equation} - \newreaction*{++reactions++}{align} -\end{lstlisting} - -Let's suppose, you'd like to have the alignment behaviour of the \lstinline=alignat= environment for `mhchem' reactions.
