## Abstract An approximate fourthβorder expression for the electron correlation energy in the MΓΈllerβPlesset perturbation scheme is proposed. It takes into account all the contributions to the fourthorder energy neglecting only those of the tripleβsubstituted determinants. It is size consistent and
The electric dipole moment (p,), dipole polarizability (CQ) and first (Balk) and second (v,,& dipole hyperpolarizability of ammonia were obtained from finite-field self-consistent-field (SCF) and complete fourth-order many-body perturbation theory (MP4) calculations. With z as the C, axis, the follo
