## Abstract A general procedure, based on the two‐point Padé approximant technique, is formulated, enabling an interpolation of the low‐lying energy levels of the PPP (Pariser–Parr–Pople) Hamiltonian over the divergency gap separating the asymptotic perturbation expansions in both strongly and weak
