[molpro-user] Triplet Phi States

[Kirk Peterson]

Ed,

you'll want to use both "occ" and "closed" cards to specify the 
occupation
of the molecular orbitals for your state of interest. Then give it 2 wf 
cards
that will state average the 2 components of the Phi, e.g.,
wf,#e's,2,2;
wf,#e's,3,2;
your occ and closed cards will determine the d and p occupations (sort 
of). One
often has to rotate your initial orbitals to get the correct orbitals 
occupied. You might
want to also calculate the lz expectation value to make sure you get a 
Phi state
and not a Pi state (although I'm not sure if a Pi state is possible in 
this case).
