Practical Application: Building a CDXML Diagram
Let's bring the abstract to life by constructing a simple CDXML energy diagram for the hydrogen molecule (H2):
<?xml version="1.0" encoding="UTF-8"?>
<cdxml>
<molecule id="H2">
<name>Hydrogen Molecule</name>
<formula>H2</formula>
<energyLevel id="1s">
<name>1s sigma</name>
<energy>-13.6 eV</energy>
<orbital type="sigma" />
</energyLevel>
<energyLevel id="1s*">
<name>1s sigma*</name>
<energy>-10.9 eV</energy>
<orbital type="sigma*" />
</energyLevel>
<plot>
<xAxis label="Energy (eV)" />
<yAxis label="Orbital Type" />
<line from="1s" to="1s*" />
</plot>
</molecule>
</cdxml>
This CDXML snippet defines a simple energy diagram for H2. The molecule element specifies the molecule's identity, and energyLevel elements define the two energy levels, 1s and 1s*.
