Hi,<br><br>I am working on a huge system ~ 4000 atoms. I am using OT + DIIS. For this method, how computational<br>expensive is it to compute the the LUMO+ states/energies. I am sure that I get the HOMO< states for free.
<br><br>This is what I am using:<br><br> &MO_CUBES<br> ADD_LAST NUMERIC<br> EACH 1<br> NLUMO -1<br> NHOMO -1<br> WRITE_CUBE F<br> &END MO_CUBES<br><br><br><br>-- <br>
