Monochromatic two beam multiphoton dissociation of CF2HCl

Abstract

Infrared multiphoton dissociation induced by monochromatic two-beam excitation has been carried out by controlling the time delay between the two laser beams. The maximum dissociation yield is found to occur at time delays around 5 μs, when the absorbed energy becomes largely stochastized and an equilibrium among the distinct processes of energy relaxation is manifested. It is shown that this behaviour essentially differs from that which occurs in dichromatic multiphoton dissociation. © 1994.This work was done under Project C187/91 supported by the Comunidad Autónoma de Madrid, and an Acción Especial N630/070 provided by the Consejo Superior de Investigaciones Cientificas (C.S.I.C.).Peer Reviewe
