Notizen:
It is shown that the exact pair-cluster coefficients corresponding to the fully correlated limit of cyclic polyene model satisfy the equations of the approximate coupled-pair theory with quadruples (ACPQ) approach, but do not represent any solution of the standard coupled-cluster method with doubles (CCD) equations. Implications of this result for the performance of various coupled-cluster (CC) approaches, when applied to cyclic polyene model, are discussed.
