Re^6: Starting virtual orbitals for MCSCF

Pavlo Solntsev


I am looking a way to generate symmetry adapted NBO type orbitals as starting orbitals for MCSCF. I found AONBO keyword works fine and i can see NBO orbitals in a PUNCH file. Is there any way i can punch NLMO orbitals by using AONLMO or strictly speaking all orbitals from They are in the OUTPUT file but not in PUNCH file. If it is a limitation, could please add this request  to your list "TODO".

Thank you.
