\section{Main Commands}
All molecular orbital (MO) diagrams are created using the environment
\env{MOdiagram}{}.
-\subsection{The \cmd{atom} Command}
-\begin{beschreibung}
- \Befehl{atom}[<name>]{left|right}\ma{<AO-spec>} \\
- \oa{<name>} caption of the atom;\\
- \ma{left|right} on the left or the right in the diagram;\\
- \ma{<AO-spec>} specifications of the \acp{AO}.
-\end{beschreibung}
+\subsection{The \cs*{atom} Command}
+\begin{commands}
+ \command{atom}[\oarg{name}\Marg{\meta{left}|\meta{right}}\marg{AO-spec}]
+ Place an \acs{AO} in the diagram. \meta{name} is caption of the atom,
+ \meta{left} and \meta{right} determine the placement in the diagram,
+ \meta{AO-spec} is the specification of the \ac{AO}.
+\end{commands}
+
Let's take a look at an example:
-\begin{beispiel}
- \begin{MOdiagram}
- \atom{right}{
- 1s = { 0; pair} ,
- 2s = { 1; pair} ,
- 2p = {1.5; up, down }
- }
- \end{MOdiagram}
-\end{beispiel}
+\begin{example}[side-by-side]
+ \begin{MOdiagram}
+ \atom{right}{
+ 1s = { 0; pair} ,
+ 2s = { 1; pair} ,
+ 2p = {1.5; up, down }
+ }
+ \end{MOdiagram}
+\end{example}
-As you can see, the argument \ma{<AO-spec>} is essential to create the actual
+As you can see, the argument \meta{AO-spec} is essential to create the actual
orbitals and the electrons within. You can use these key/value pairs to specify
what you need:
-\begin{beschreibung}
- \Option{1s}{<rel-energy>; <el-spec>}
- \Option{2s}{<rel-energy>; <el-spec>}
- \Option{2p}{<rel-energy>; <x el-spec>, <y el-spec>, <z el-spec>} \\
- \code{<el-spec>} can have the values \code{pair}, \code{up} and \code{down} or
- can be left empty. \code{<rel-energy>} actually is the $y$ coordinate and shifts
- the \ac{AO} vertically by \code{<rel-energy>} \si{\centi\metre}.
-\end{beschreibung}
-
-The argument \ma{left|right} is important, when p orbitals are used. For instance
-compare the following example to the one before:
-\begin{beispiel}
- \begin{MOdiagram}
- \atom{left}{
- 1s = { 0; pair} ,
- 2s = { 1; pair} ,
- 2p = {1.5; up, down }
- }
- \end{MOdiagram}
-\end{beispiel}
+\begin{options}
+ \keychoice{1s}{\{\meta{rel-energy}; \meta{el-spec}\}}
+ Energy level and electron specifications for the 1s orbital.
+ \keychoice{2s}{\{\meta{rel-energy}; \meta{el-spec}\}}
+ Energy level and electron specifications for the 2s orbital.
+ \keychoice{2p}{\{\meta{rel-energy}; \meta{x el-spec}{,} \meta{y el-spec}{,}
+ \meta{z el-spec}\}}
+ Energy level and electron specifications for the 2p orbitals.
+\end{options}
+\meta{el-spec} can have the values \code{pair}, \code{up} and \code{down} or
+can be left empty. \meta{rel-energy} actually is the $y$ coordinate and shifts
+the \ac{AO} vertically by \meta{rel-energy} \si{\centi\metre}.
+
+The argument \meta{left}/\meta{right} is important, when p~orbitals are used.
+For instance compare the following example to the one before:
+\begin{example}[side-by-side]
+ \begin{MOdiagram}
+ \atom{left}{
+ 1s = { 0; pair} ,
+ 2s = { 1; pair} ,
+ 2p = {1.5; up, down }
+ }
+ \end{MOdiagram}
+\end{example}
When both variants are used one can also see, that the right atom is shifted to
the right (hence the naming). The right atom is shifted by \SI{4}{\centi\metre}
per default and can be adjusted individually, see page~\pageref{option:distance}.
-\begin{beispiel}[below]
- \begin{MOdiagram}
- \atom{left}{
- 1s = { 0; pair} ,
- 2s = { 1; pair} ,
- 2p = {1.5; up, down }
- }
- \atom{right}{
- 1s = { 0; pair} ,
- 2s = { 1; pair} ,
- 2p = {1.5; up, down }
- }
- \end{MOdiagram}
-\end{beispiel}
-With the command \cmd{molecule} (section~\ref{ssec:molecule}) the reason for the
+\begin{example}
+ \begin{MOdiagram}
+ \atom{left}{
+ 1s = { 0; pair} ,
+ 2s = { 1; pair} ,
+ 2p = {1.5; up, down }
+ }
+ \atom{right}{
+ 1s = { 0; pair} ,
+ 2s = { 1; pair} ,
+ 2p = {1.5; up, down }
+ }
+ \end{MOdiagram}
+\end{example}
+With the command \cs{molecule} (section~\ref{ssec:molecule}) the reason for the
shift becomes clear.
Any of the arguments for the \ac{AO} can be left empty or be omitted.
-\begin{beispiel}
- Without argument: default height, full:
- \begin{MOdiagram}
- \atom{left}{1s, 2s, 2p}
- \end{MOdiagram}
-\end{beispiel}
-\begin{beispiel}
- empty argument: default height, empty:
- \begin{MOdiagram}
- \atom{left}{1s=, 2s=, 2p=}

-\subsection{The \cmd{molecule} Command}\label{ssec:molecule}
-\begin{beschreibung}
- \Befehl{molecule}[<name>]{<MO-spec>} \\
- \oa{<name>} caption of the molecule; \\
- \ma{<MO-spec>} specifications of the \acp{MO};
-\end{beschreibung}
+\begin{example}[side-by-side]
+ Without argument: default height, full:\par
+ \begin{MOdiagram}
+ \atom{left}{1s, 2s, 2p}
+ \end{MOdiagram}
+\end{example}
+
+\begin{example}[side-by-side]
+ empty argument: default height, empty:\par
+ \begin{MOdiagram}
+ \atom{left}{1s=, 2s=, 2p=}
+ \end{MOdiagram}
+\end{example}
+
+\begin{example}[side-by-side]
+ using some values:\par
+ \begin{MOdiagram}
+ \atom{left}{1s, 2s=1, 2p={;,up} }
+ \end{MOdiagram}
+\end{example}
+
+\subsection{The \cs*{molecule} Command}\label{ssec:molecule}
+\begin{commands}
+ \command{molecule}[\oarg{name}\marg{MO-spec}]
+ Place a \acs{MO} in the diagram. \meta{name} is caption of the molecule,
+ \meta{MO-spec} is the specification of the \ac{MO}.
+\end{commands}
+
An example first:
-\begin{beispiel}
- \begin{MOdiagram}
- \atom{left} { 1s = { 0; up } }
- \atom{right}{ 1s = { 0; up } }
- \molecule { 1sMO = {.75; pair } }
- \end{MOdiagram}
-\end{beispiel}
-The command \cmd{molecule} connects the \acp{AO} with the bonding and anti-bondung
-\acp{MO}. \cmd{molecule} can only be used \emph{after} one has set \emph{both}
-atoms since the orbitals that are to be connected must be known.
-
-The argument \ma{<MO-spec>} accepts a comma separated list of key/value pairs:
-\begin{beschreibung}
- \option{1sMO}{<energy gain>/<energy loss>; <s el-spec>, <s* el-spec>}
- connects the \acp{AO} specified by \key{1s}.
- \option{2sMO}{<energy gain>/<energy loss>; <s el-spec>, <s* el-spec>}
- connects the \acp{AO} specified by \key{2s}.
- \option{2pMO}{<s energy gain>/<s energy loss>, <p energy gain>/<p energy loss>;
- <s el-spec>, <py el-spec>, <pz el- spec>, <py* el-spec>, <pz* el-spec>,
- <s* el-spec>}
- connects the \acp{AO} specified by \key{2p}.
-\end{beschreibung}
+\begin{example}[side-by-side]
+ \begin{MOdiagram}
+ \atom{left} { 1s = { 0; up } }
+ \atom{right}{ 1s = { 0; up } }
+ \molecule { 1sMO = {.75; pair } }
+ \end{MOdiagram}
+\end{example}
+The command \cs{molecule} connects the \acp{AO} with the bonding and
+anti-bondung \acp{MO}. \cs{molecule} can only be used \emph{after} one has
+set \emph{both} atoms since the orbitals that are to be connected must be
+known.
+
+The argument \meta{MO-spec} accepts a comma separated list of key/value pairs:
+\begin{options}
+ \keychoice{1sMO}{\{\meta{energy gain}/\meta{energy loss}; \meta{s
+ el-spec}{,} \meta{s* el-spec}\}}
+ connects the \acp{AO} specified by \option{1s}.
+ \keychoice{2sMO}{\{\meta{energy gain}/\meta{energy loss}; \meta{s
+ el-spec}{,} \meta{s* el-spec}\}}
+ connects the \acp{AO} specified by \option{2s}
+ \keychoice{2pMO}{\{\meta{s energy gain}/\meta{s energy loss}{,} \meta{p
+ energy gain}/\meta{p energy loss}; \meta{s el-spec}{,} \meta{py
+ el-spec}{,} \meta{pz el- spec}{,} \meta{py* el-spec}{,} \meta{pz*
+ el-spec}{,} \meta{s* el-spec}\}}
+ connects the \acp{AO} specified by \option{2p}.
+\end{options}
+
Obviously the regarding \acp{AO} must have been set in order to connect them.
This for example won't work:
-\begin{beispiel}[code only]
- \begin{MOdiagram}
- \atom{left} { 1s = 0 }
- \atom{right}{ 1s = 0 }
- \molecule { 2sMO = .75 }
- \end{MOdiagram}
-\end{beispiel}
-The value used in \code{<energy gain>} determines how many \si{\centi\metre} the
+\begin{sourcecode}
+ \begin{MOdiagram}
+ \atom{left} { 1s = 0 }
+ \atom{right}{ 1s = 0 }
+ \molecule { 2sMO = .75 }
+ \end{MOdiagram}
+\end{sourcecode}
+The value used in \meta{energy gain} determines how many \si{\centi\metre} the
bonding \ac{MO} lies below the lower \ac{AO} or how many \si{\centi\metre} the
anti-bondung \ac{MO} lies above the higher \ac{AO}.
-\begin{beispiel}[below]
- same level:
- \begin{MOdiagram}
- \atom{left} { 1s = { 0; up } }
- \atom{right}{ 1s = { 0; up } }
- \molecule { 1sMO = {.75; pair } }
- \end{MOdiagram}
-
- different levels:
- \begin{MOdiagram}
- \atom{left} { 1s = { 0; up } }
- \atom{right}{ 1s = { 1; up } }
- \molecule { 1sMO = {.25; pair } }
- \end{MOdiagram}
-\end{beispiel}
-
-If you specify \code{<energy loss>} you can create non-symmetrical splittings.
-Then, the first value (\code{<energy gain>}) is used for the bonding \ac{MO} and
-the second value (\code{<energy loss>}) is used for the anti-bonding \ac{MO}.
-\begin{beispiel}[below]
- \begin{MOdiagram}
- \atom{left} { 1s = { 0; up } }
- \atom{right}{ 1s = { 0; up } }
- \molecule { 1sMO = {.75/.25; pair } }
- \end{MOdiagram}
-
- \begin{MOdiagram}

+\end{example}
+
+If you specify \meta{energy loss} you can create non-symmetrical splittings.

+ \atom{right}{ 1s = { 1; up } }
+ \molecule { 1sMO = {.25/.75; pair } }
+ \end{MOdiagram}
+\end{example}
Please be aware, that you have to specify \emph{two} such values or pairs with
-\key{2pMO}: the splitting of the \textsigma\ orbitals and the splitting of the
-\textpi\ orbitals.
-\begin{beispiel}
- \begin{MOdiagram}
- \atom{left} { 2p = { 0; up, up } }

To create diagrams like this there is the following command, which draws a single
\ac{AO}:
-\begin{beschreibung}
- \Befehl{AO}[<name>]\da{<xshift>}\ma{<type>}\oa{<key = val>}\ma{<energy>;<el-spec>} \\
- \oa{<name>} (optional) name of the node; if not specified, \code{AO\#} is used where
- \code{\#} is a consecutive number. \\
- \oa{<xshift>} vertical position of the orbitals, a \TeX\ dimension. \\
- \ma{<type>} \code{s} or \code{p}. \\
- \oa{<key = val>} key/value pairs with which the \ac{AO} can be customized, see
- section~\ref{ssec:AO_anpassen}. \\
- \ma{<AO-spec>} specification of the \ac{AO}.
-\end{beschreibung}
-
-Depending on the \code{<type>} one s or three p orbitals are drawn.
-\begin{beispiel}
- \begin{MOdiagram}
- \AO{s}{0;}
- \AO(-20pt){p}{1;pair,up,down}
- \end{MOdiagram}
-\end{beispiel}
-
-If one wants to place such an \ac{AO} at the position of an atom, one has to know
-their \code{<xshift>}. They have predefined values (also see
+\begin{commands}
+ \command{AO}[\oarg{name}\darg{xshift}\marg{type}\oarg{options}\Marg{\meta{energy};
+ \meta{el-spec}}]
+ Place an \acs{AO} in the diagram. \meta{<name>} (optional) is the name of
+ the node; if not specified, \code{AO\#} is used where \code{\#} is a
+ consecutive number. \meta{xshift} is the vertical position of the orbital(s),
+ a \TeX\ dimension. \meta{type} can be \code{s} or \code{p}.
+ \meta{options} is a list of key/value pairs with which the \ac{AO} can be
+ customized, see section~\ref{ssec:AO_anpassen}. \meta{AO-spec} is the
+ specification of the \ac{AO}.
+\end{commands}
+
+Depending on the \meta{type} one s or three p orbitals are drawn.

Within the p orbitals there is an additional shift by \SI{20}{pt} per orbital.
This is equivalent to a double shift by the length \code{AO-width} (see
section~\ref{option:AO-width}):
-\begin{beispiel}
- \begin{MOdiagram}
- \atom{left} {2p=0}
- \atom{right}{2p=0}
- % above the left atom:
- \AO(1cm) {s}{ .5}
- \AO(1cm-20pt){s}{ 1;up}
- \AO(1cm-40pt){s}{1,5;down}
- % above the right atom:
- \AO(5cm) {s}{ .5}
- \AO(5cm+20pt){s}{ 1;up}
- \AO(5cm+40pt){s}{1.5;down}
- \end{MOdiagram}
-\end{beispiel}
-
-The \acp{AO} created with \cmd{AO} also can be connected. For this you can use
-the \TikZ command \cmd{draw}, of course. You can use the predefined node names\ldots
-\begin{beispiel}
- \begin{MOdiagram}
- \AO{s}{0} \AO(2cm){s}{1}
- \AO{s}{2} \AO(2cm){s}{1.5}
- \draw[red] (AO1.0) -- (AO2.180) (AO3.0) -- (AO4.180);

+
+The \acp{AO} created with \cs{AO} also can be connected. For this you can use

- \AO[a]{s}{0} \AO[b](2cm){s}{1}
- \AO[c]{s}{2} \AO[d](2cm){s}{1.5}
- \draw[red] (a.0) -- (b.180) (c.0) -- (d.180);

+ \draw[red] (a.0) -- (b.180) (c.0) -- (d.180);
+ \end{MOdiagram}

-\code{AO1x}, \code{AO1y}, \code{AO1z}, \code{AO2x} \etc for the type \code{p}.
-Nodes of the type \code{p} get an \code{x}, \code{y} or \code{z} if you specify
-your own name, too.

- \begin{MOdiagram}
- \AO{p}{0}
- \draw[<-,shorten >=5pt] (AO1y.-90) -- ++ (.5,-1) node {y};

+ \command{connect}[\marg{AO-connect}]
+ Connects the specified \acp{AO}. \meta{AO-connect} is comma separated

+\end{commands}
This command expects a comma separated list of node name pairs that are to be
connected. The names have to be connected with a \code{\&}:
-\begin{beispiel}

-
-Some things still need to be said: \cmd{connect} adds the anchor \code{east} to
-the first name and the anchor \code{west} to the second one. This means a
-connection only makes sense from the left to the right. However, you can add own
-anchors using the usual \TikZ way:
-\begin{beispiel}
- \begin{tikzpicture}
- \draw (0,0) node (a) {a} ++ (1,0) node (b) {b}
- ++ (0,1) node (c) {c} ++ (-1,0) node (d) {d} ;

+\end{sourcecode}
+
+\subsubsection{Option \option*{style}}\label{option:style}
There are five different styles which can be chosen.
\begin{itemize}
- \item\key{style}{plain} \AOinline[style=plain]{pair} (default)
- \item\key{style}{square} \AOinline[style=square]{pair}
- \item\key{style}{circle} \AOinline[style=circle]{pair}
- \item\key{style}{round} \AOinline[style=round]{pair}
- \item\key{style}{fancy} \AOinline[style=fancy]{pair}
+ \item\keyis{style}{plain} \AOinline[style=plain]{pair} (default)
+ \item\keyis{style}{square} \AOinline[style=square]{pair}
+ \item\keyis{style}{circle} \AOinline[style=circle]{pair}
+ \item\keyis{style}{round} \AOinline[style=round]{pair}
+ \item\keyis{style}{fancy} \AOinline[style=fancy]{pair}
\end{itemize}
Let's take the \ac{MO} diagram of \ch{H2} to illustrate the different styles:
-\begin{beispiel}
- % use package `chemmacros'
- \begin{MOdiagram}[style=plain]% default
- \atom[H]{left} { 1s = {;up} }
- \atom[H]{right}{ 1s = {;up} }
- \molecule[\ch{H2}]{ 1sMO = {.75;pair} }
- \end{MOdiagram}
-\end{beispiel}
-\begin{beispiel}
- % use package `chemmacros'
- \begin{MOdiagram}[style=square]
- \atom[H]{left} { 1s = {;up} }
- \atom[H]{right}{ 1s = {;up} }
- \molecule[\ch{H2}]{ 1sMO = {.75;pair} }
- \end{MOdiagram}
-\end{beispiel}
-\begin{beispiel}
- % use package `chemmacros'
- \begin{MOdiagram}[style=circle]

- \end{MOdiagram}
-\end{beispiel}
-\begin{beispiel}
- % use package `chemmacros'
- \begin{MOdiagram}[style=round]
- \atom[H]{left} { 1s = {;up} }
- \atom[H]{right}{ 1s = {;up} }
- \molecule[\ch{H2}]{ 1sMO = {.75;pair} }
- \end{MOdiagram}
-\end{beispiel}
-\begin{beispiel}

- \molecule[\ch{H2}]{ 1sMO = {.75;pair} }
- \end{MOdiagram}
-\end{beispiel}
-
-\subsubsection{Option \key{distance}}\label{option:distance}
-Depending on labels and captions the \SI{4}{\centi\metre} by which the right and
-left atom are separated can be too small. With \key{distance}{<dim>} the length
-can be adjusted. This will change the position of the right atom to \code{1cm + <dim>}
-and the position of the molecule is changed to \code{0.5*(1cm + <dim>)}, also see
-page~\pageref{xshift} and section~\ref{orbital-positionen}.
-\begin{beispiel}
- % use package `chemmacros'
- \begin{MOdiagram}[distance=6cm]
- \atom[H]{left} { 1s = {;up} }
- \atom[H]{right}{ 1s = {;up} }
- \molecule[\ch{H2}]{ 1sMO = {.75;pair} }
- \end{MOdiagram}
-\end{beispiel}
-
-\subsubsection{Option \key{AO-width}}\label{option:AO-width}
-The length \key{AO-width} sets the length of the horizontal line in a orbital
-displayed with the \code{plain} style. It's default value is \SI{10}{pt}.
-\begin{beispiel}
- % use package `chemmacros'
- \begin{MOdiagram}[AO-width=15pt]
- \atom[H]{left} { 1s = {;up} }
- \atom[H]{right}{ 1s = {;up} }
- \molecule[\ch{H2}]{ 1sMO = {.75;pair} }
- \end{MOdiagram}
-\end{beispiel}
-\begin{beispiel}

- \atom[H]{right}{ 1s = {;up} }
- \molecule[\ch{H2}]{ 1sMO = {.75;pair} }
- \end{MOdiagram}
-\end{beispiel}
-By changing the value of \key{AO-width} the positions of the p and the \textpi\
-orbitals also change, see section~\ref{orbital-positionen}.

+\subsubsection{Option \option*{distance}}\label{option:distance}
+Depending on labels and captions the \SI{4}{\centi\metre} by which the right
+and left atom are separated can be too small. With \key{distance}{dim} the
+length can be adjusted. This will change the position of the right atom to
+\code{1cm + \meta{dim}} and the position of the molecule is changed to
+\code{0.5*(1cm + \meta{dim})}, also see page~\pageref{xshift} and
+section~\ref{orbital-positionen}.
+\begin{example}[side-by-side]

+ \end{MOdiagram}
+\end{example}
+
+\subsubsection{Option \option*{AO-width}}\label{option:AO-width}

+\end{example}
+By changing the value of \option{AO-width} the positions of the p and the

+
+\subsubsection{Optionen \option*{el-sep}, \option*{up-el-pos} und
+ \option*{down-el-pos}}
+\label{option:electrons}
+
These three options change the horizontal positions of the arrows representing
-the electrons in an \ac{AO}/\ac{MO}. The option \key{el-sep}{<num>} needs a value
-between \code{0} and \code{1}. \code{0} means \emph{no} distance between the arrows
-and \code{1} \emph{full} distance (with respect to the length \key{AO-width}, see
-section~\ref{option:AO-width}).
-\begin{beispiel}
- % use package `chemmacros'

+ \end{MOdiagram}
+\end{example}
+
The options \key{up-el-pos}{<num>} and \key{down-el-pos}{<num>} can be used
-alternatively to place the spin-up and spin-down electron, respectively. Again
-they need values between \code{0} and \code{1}. This time \code{0} means \emph{on
-the left} and \code{1} means \emph{on the right}.

- \molecule[\ch{H2}]{ 1sMO = {.75;pair} }
- \end{MOdiagram}
-\end{beispiel}
-
-\subsubsection{Option \key{names}}\label{option:names}
-If you use the option \key{names} the atoms and the molecule get captions provided
-you have used the optional \code{<name>} argument of \cmd{atom} and/or \cmd{molecule}.
-\begin{beispiel}
- % use package `chemmacros'

-\end{beispiel}
-
-\subsubsection{Optionens \key{names-style} and \key{names-style-add}}\label{option:names_style}
-These options enable to customize the style of the captions of the atoms and of

+\subsubsection{Option \option*{lines}}\label{option:lines}
+The option \option{lines} can be used to modify the \TikZ\ style of the

+\subsubsection{Options \option*{names-style} and \option*{names-style-add}}\label{option:names_style}
+These options enable to customize the style of the captions of the atoms and

+\key{names-style}{anchor=base}\footnote{Please see ``\TikZ\ and PGF -- Manual
+ for Version 2.10'' p.\,183 section 16.4.4 (pgfmanual.pdf) for the meaning}.
+\begin{example}[side-by-side]

+ \atom[b]{right}{ 1s = {;up} }
+ \molecule[\ch{X2}]{ 1sMO = {.75;pair} }
+ \end{MOdiagram}
+\end{example}
+
With this the default setting is overwritten. As you can see it destroys the
vertical alignment of the nodes. In order to avoid that you can for example
specify \code{text height} and \code{text depth} yourself \ldots
-\begin{beispiel}
- % use package `chemmacros'
- \begin{MOdiagram}[names,names-style={text height=1.5ex, text depth=.25ex, draw=blue}]
- \atom[p]{left} { 1s = {;up} }
- \atom[b]{right}{ 1s = {;up} }
- \molecule[\ch{X2}]{ 1sMO = {.75;pair} }
- \end{MOdiagram}
-\end{beispiel}
+\begin{example}
+ % use package `chemmacros'
+ \begin{MOdiagram}[names,names-style={text height=1.5ex, text depth=.25ex, draw=blue}]

+ \atom[b]{right}{ 1s = {;up} }
+ \molecule[\ch{X2}]{ 1sMO = {.75;pair} }
+ \end{MOdiagram}
+\end{example}
+
\ldots, add the \code{anchor} again \ldots
-\begin{beispiel}
- % use package `chemmacros'
- \begin{MOdiagram}[names,names-style={anchor=base, draw=blue}]
- \atom[p]{left} { 1s = {;up} }
- \atom[b]{right}{ 1s = {;up} }
- \molecule[\ch{X2}]{ 1sMO = {.75;pair} }
- \end{MOdiagram}

+ \atom[b]{right}{ 1s = {;up} }
+ \molecule[\ch{X2}]{ 1sMO = {.75;pair} }
+ \end{MOdiagram}
+\end{example}
+
\ldots\ or use the option \key{names-style-add}. It doesn't overwrite the
current setting but appends the new declaration:
-\begin{beispiel}
- % use package `chemmacros'
- \begin{MOdiagram}[names,names-style-add={draw=blue}]
- \atom[p]{left} { 1s = {;up} }
- \atom[b]{right}{ 1s = {;up} }
- \molecule[\ch{X2}]{ 1sMO = {.75;pair} }
- \end{MOdiagram}
-\end{beispiel}
-\begin{beispiel}
- % use package `chemmacros'
- \MOsetup{names,names-style={text height=2.5ex,text depth=.5ex,draw=blue!80,rounded corners}}
- \begin{MOdiagram}
- \atom[p]{left} { 1s = {;up} }
- \atom[b]{right}{ 1s = {;up} }
- \molecule[\ch{X2}]{ 1sMO = {.75;pair} }
- \end{MOdiagram}
- \begin{MOdiagram}[names-style-add={fill=blue!20}]
- \atom[p]{left} { 1s = {;up} }
- \atom[b]{right}{ 1s = {;up} }
- \molecule[\ch{X2}]{ 1sMO = {.75;pair} }
- \end{MOdiagram}
-\end{beispiel}
-
-\subsubsection{Option \key{labels}}\label{option:labels}
-If you use the option \key{labels} predefined labels are written below the
-orbitals. These labels can be changed, see section~\ref{sec:key:label}.
-\begin{beispiel}
