 which would account for the frequency-dependent magnetizability of a molecule in the presence of an optical field, represented as a monochromatic wave, has been investigated. It has been shown that, whereas the electric dipole moment induced by the incident wave is origin independent, the magnetic dipole depends on the origin and cannot be rationalized via a function

. This result was arrived at using time-dependent perturbation theory, within dipole, quadrupole, and octopole approximations for the interaction Hamiltonian, employing a series of relationships, which describe the change of molecular response tensors in a change of origin of the coordinate system.
