Cluster perturbation theory. III. Perturbation series for coupled cluster singles and doubles excitation energies
(2020-05-07)
The cluster perturbation series, CPS(D), for coupled cluster singles and doubles excitation energies is considered. It is demonstrated that the second-order model CPS(D-2) is identical to the configuration interaction ...
