✦ Synopsis

The fundamental plus the doubled output of a pulsed dye laser have been used to induce two-photon, laser-assisted reactions in low pressure gas mixtures of Xe with Brr, CC&, CCI,Br, CC&Brr and I,. Tbe products are XeCI( B, C), XeBr(B, C) or XeI(B, C) following two-photon promotion to the reactive ion-pair potentials. The utilization of a two-color scheme enhances the twophoton, laser-assisted reactions because of better match with an intermediate state of the reagent molecule. Product selectivity with a propensity for XeCl (B, C) formation from CCl,Br and CCI,Br, by the laser-assisted reactions, relative to the full collisions with Xe( 6s) or Xe(6p) atoms, is demonstrated.
