A general formalism is set up to apply the variation‐perturbation method to the quantum theory of non‐linear optical effects, in particular to the electric and magnetic birefringence (Kerr and Cotton‐Mouton effects). The quantities describing these effects are obtained from the wave function Ψ 0 (0)of the ground state of the unperturbed molecule and the different vectors and tensors which are determined by a variation method. With this method an approximate computation of the Kerr and Cotton‐Mouton constants of some simple molecules has been made.
