We have summarized the solutions of the SAC (symmetry-adapted-cluster) and SAC CI theories for the study of electron correlations in ground and excited states, respectively. Variational and non-variational solutions are considered for both theories and their features are discussed.

A method for excited states is givepn on the bzsis of the symmetry-adapted-cluster (SAC) expansion method. It is based on the fact that the SAC expansion method &es inci;lentally a set of excited functions which satisfies the Brillouin theorem with the ground state.
The generalized version of the symmetry adapted cluster theory (GSAC) which has been developed recently is nearly sizeconsistent and applicable to general classes of nonclosed-shell systems. The generality and the accuracy of the method have been tested for the symmetric dissociation of H,O. The ele
We have discussed the utility of the cluster expansion of the wavefunction and proposed a pseudo+rbital theory which constitutes a generalization of the orbital-theoretic idea It has been applied to the calculation of spin densities of the fustrow atoms.
