The phenomenon of Multiple Photon Excitation (MPE) of polyatomic molecules by a (laser) optical field has proved to be quite general. We have been attempting for some time to relate the absorption response of a molecule to the optical driving force in terms of a general model which would take into account the important molecular parameters. A picture of the interaction has emerged which emphasizes the dynamics of absorption within a single vibrational manifold with rapid intramodal coupling to other vibrational modes. The similarity between this picture of the excitation process by an optical field and the de-excitation process for vibrational relaxation of polyatomics provided strong motivation to seek a universal curve for the MPE process by analogy to the Lambert--Salter correlation for relaxation processes.
