By efficiently combining coupled-cluster iterations with the 2 n + 1 rule of perturbation theory, we report full sixth-order MBPT. All terms are evaluated with a Hartree-Fock reference and the Moller-Plesset separation of the Hamiltonian and less than an n 9 procedure. The total correction correspon

Although the physical significance of Kohn-Sham orbitals is only given by the ground state density of the Kohn-Sham quasi-particle system they nevertheless form a single-particle system, which may serve as a basis for perturbation theory or variational methods.

A zero-order wave function of a dimer is defined as the antisymmetrized product of monomer HartreeαFock wave functions. A symmetry-adapted many-body perturbation theory is developed up to the third order to obtain interaction energies at the HartreeαFock level. Correlation effects are accounted for
