Abstract
Full configuration-interaction (FCI) calculations have been performed for the ã 1A1−b1B1and ã 1A1−(2)1A1transitions in CH2 and for selected dipole and quadrupole transitions in BeO. The FCI transition moments are compared to those obtained from correlation treatments that truncate the n-particle expansion. The state-averaged MCSCF/SOCI and FCI results agree well, even for BeO, where the CASSCF level nonorthogonal transition moment differs from the state-averaged CASSCF transition moment.
