Use the Window option to define a different orbital set. Options Singlets Solve only for singlet excited states. Only effective for closed-shell systems, for which it is the default.
Triplets Solve only for triplet excited states.
Only effective for closed-shell systems. 50-50 Solve for half triplet and half singlet states. Only effective for closed-shell systems. N Read converged states off the checkpoint file and solve for an additional N states. The two values specify the starting and ending orbitals to be used.
