Reactions and Spectroscopy of Excited Nitrenes

Abstract

This report describes the results of an 18 month research program in which reactions and energy transfer processes involving excited NCl(a1 Delta) were investigated. The work included three projects. In the first of these, high densities (> 10(exp 15/cu cm) of NCl(a1 Delta) were produced by photodissociation of CIN3, and excited I(5 sup 2 P 1/2) atoms were generated by a subsequent energy transfer process. The data suggest that a population inversion on the I(5 sup 2p 3/2) - I(5 sup 2 P 3/2) transition was achieved, but the inversion density was insufficient to reach laser threshold in the optical cavity employed. In the second project, rate constants for collisional quenching of NCl(a1 Delta) by a number of atoms and diatomic molecules were measured. In the third project, the production of NCl(a1 Delta) by the H + NC12 reaction was investigated in a continuous transverse-flow reactor, at high reagent densities.
