modiagram
package.
Summary description: Easy drawing of molecular orbital diagrams. License type: lppl
Announcement text: ----------------------------------------------------------------------
The environment 'MOdiagram' and some commands are provided to create molecular orbital diagrams using the TikZ package.
The MO diagram of Dihydrogen would be set like: egin{MOdiagram} atom{left}{ 1s = {0;up} } atom{right}{ 1s = {0;up} } molecule{ 1sMO = {1;pair, } } end{MOdiagram}
MOdiagram loads the packages 'expl3', 'xparse' and 'l3keys2e', which means it needs LaTeX3 support as provided by the package bundles 'l3kernel' and 'l3packages'. ----------------------------------------------------------------------
