[en] A method of separating two isotope components of a gaseous mixture is described. The mixture is iradiated with coherent polarised electromagnetic radiation. The frequency and electric field strength of the radiation are selected so that the irradiation preferentially excites dipole moment oscillation of molecules of one isotope component. The phasing of the oscillation excited is, at least at the steady-state amplitude of selected oscillation, substantially opposite to that of the electric field of the radiation
