<p>Hello, developers for COLUMBUS7.0</p>
<p><br>
</p>
<p>I am In Seong Lee and I have a question for determining the spin configuration.</p>
<p><br>
</p>
<p>I run MCSCF and MRCI calculation with hydrogen dimer system.</p>
<p><br>
</p>
<p>From mcpcls, cipcls, natural orbitals, I can know that the electronic configuration of certain excited state is following.</p>
<p>(I denote the bonding orbital as sigma_g and the anti-bonding orbital as sigma_u for each monomer.)</p>
<p><br>
</p>
<p>ex) one H<sub>2</sub> monomer -> sigma_g has 1 e-, sigma_u has 1 e-</p>
<p> another H<sub>2</sub> monomer -> sigma_g has 1 e-, sigma_u has 1 e-.</p>
<p>(For ground state, one hydrogen monomer has 2 e-s in sigma_g, the other hydrogen also has 2 electrons in sigma_g)</p>
<p><br>
</p>
<p>In this excited state, I want to know which electrons have which direction of spin.</p>
<p><br>
</p>
<p>In other words, for example, 1sigma_g: up, 1sigma_u: up, 2sigma_g: down, 2sigma_u: down.</p>
<p>(In this sentence, 1 means one hydrogen monomer and 2 indicates the other monomer.)</p>
<p>Or, 1sigma_g: up, 1sigma_u : down, 2sigma_g: up, 2sigma_u: down, etc.</p>
<p><br>
</p>
<p>Therefore, I want to check the spin information for each certain excited state.</p>
<p><br>
</p>
<p>How can I check this information from which file?</p>
<p><br>
</p>
<p>Thanks for reading my mail.</p>
<p><br>
</p>
<p>In Seong Lee.</p>
