It is proposed that the calculation of non-dynamical electronic correlation effects by the complete active space self-consistent field (CASSCF) method can be extended by the inclusion of dynamical correlation effects through the use of a suitably modified single-reference coupled-cluster (CC) proced

The nonlinear coupled-cluster (CC) equations possess several solutions. They describe various excited states as long as they contain a contribution from the reference function. We study the additional solutions of the single-reference CC equations and demonstrate that unlike the ground state, the ap
