Dear all,
I want to do CASSCF(4,4) and restrict my active space to pi and pi*
orbitals for carbon dimer . Orbitals 5-6-8-9 have pi symmetry so I
decided to rotate 7 and 9 to have pure pi active space. In output, I can
see "ROTATION OF ORBITALS 9.1 7.1 90.00 DEGREES" but
apparently orbital order goes back to original order during the
calculation and final results (orbitals and energy) looks exactly same
if I remove rotate keyword. is there anyway to force molpro to keep the
order?
Any clarification appreciated,
Thank you,
Kaveh Haghighi Mood
