Re: MCSCF calculation with and without state averaging / merits and drawbacks

State-averaging is necessary when you study quasi-degenerate or excited states. In state-specific calculation, the resulting orbitals are best for the selected state, while in the state-averaged calculation the orbitals are sort of compromise, because they are best for several states. However, state-averaging is the only way to obtain a common set of orbitals for several states.
