Moller-Plesset Perturbation Theory: Energy Corrections and Wavefunction Expansion

This lecture covers the continuation of Moller-Plesset Perturbation Theory, focusing on the perturbation energy corrections and the expansion of the perturbed wavefunction in doubly excited Slater determinants. It explains the 1st and 2nd order corrections to the energy, the basis functions in Moller-Plesset theory, and the 0th order energy. The lecture also includes a quiz on Moller-Plesset theory and its solutions, emphasizing the importance of understanding the energy corrections and wavefunction expansion in quantum chemistry.
