Intense field resonance Raman scattering by a molecular continuum: A coupled equations study

摘要

Resonance Raman scattering (RRS) via a dissociative molecular electronic state has been studied numerically by a coupled equations approach from low (sim;108W/cm2) to high (1010W/cm2) field intensities for the Ar+2diatomic molecule.Laserinducedresonancestates found in a previous calculation lsqb;A. D. Bandrauk and M. L. Sink, J. Chem. Phys. 74, 1110 (1981)rsqb; are shown to be detectable by RRS. The stability of these states is examined in detail at high field strengths and the validity of the rotating wave approximation (RWA) is also verified. It is shown that the semiclassical theory of predissocation is a very useful tool to locate all laserhyphen;induced bound states which appear as resonances in the coupled equations formalism.
