Abstract
Two theorems are presented which increase the scope of double perturbation theory. First, an interchange theorem is found for polarizabilities at complex-valued frequencies. Second, a form of double perturbation theory is developed which does not assume the existence of an unperturbed Hamiltonian relating the unperturbed and perturbed wavefunctions.Keywords
