Dear All,

I wonder if it's possible with molpro to calculate
symmetry allowed conical intersections between
excited states (of different symmetry) at the
EOM-CCSD level. Specifically, I wonder if one can
perform optimization of (Ei-Ej) (or (Ei-Ej)²),
where Ei,Ej - energies of ith and jth excited states.
Did anyone try to do something like that? Thanks!
