Møller-Plesset theory truncated at 4th order.
(Møller-Plesset Theory, 4th order) A perturbative approximation for including electron correlation, using the Hartree-Fock wavefunction as the zeroth order wavefunction. MP4 refers to the fourth order energy correction. MP4 as implemented in GAUSSIAN can be calculated using various configurations. For example, MP4SDQ means that all terms involving singles, doubles and quadruples configurations are included through fourth order.
