Two-Photon Direct Laser-Assisted Reaction between Xe and ClF

Article abstract of DOI:10.1021/j100167a004

The two-photon laser-assisted reaction between Xe and ClF under dilute gas conditions is demonstrated.The only product is XeCl(B,C) in contradistinction to the reactions of Xe(6s) and Xe(6p) atoms with ClF or the reaction of ClF(4s^1,3Π) with Xe, which give both XeCl(B,C) and XeF(B,C).The excitation spectra from the laser-assisted reaction Xe/ClF and Xe/Cl2 are compared.Arguments based upon product-state distributions and the laser intensity dependence are summarized to favor a direct, rather than a stepwise, mechanism for the laser-assisted reactions of Xe with halogens under dilute gas conditions.
