Abstract
Stationary perturbation theory is one of the main approximation methods in quantum mechanics. It applies to quantum systems with a Hamiltonian which, in a sense that will be made clear, is close to a Hamiltonian whose eigenvalues and eigenvectors are known. We will develop the formalism and use it to investigate the effect of the spatial extension of the nucleus on electronic energies; the Stark effect and the van der Waals forces in hydrogen; and the rotation-vibration energies of a diatomic molecule.1
