Dear Molpro Users,<br><br>I'm would like to obtain the HOMO orbital energies to use for subsequent DFT-SAPT calculation that requires both the HOMO and vertical I.P.'s. I calculated the following file below and the orbitals from the output are printed below. I'm experiencing difficulty understanding which orbital is actually the HOMO. Any advice would be greatly appreciated. <br>
