Non-adiabatic Perturbation Theory
The solving of Schroedinger equation for molecular systems is usually done by first applying the Born-Oppenheimer approximation. I will describe a method, based on the idea of effective Hamiltonian, which does allow for a systematic calculation of corrections beyond the Born Oppenheimer approximation.
