BiF/NF2 Kinetics Studies: Mechanism and Conversion Efficiency

Abstract

Unraveling the complex kinetics of the Nitrogen fluoride energy transfer system has been an ongoing concern of our laboratory for the past several years. The system is of particular interest because of its potential as a visible chemical laser. Of central importance in the evaluation of this potential is a knowledge of the chemical pathways leading to the formation of electronically excited Bismuth fluoride. This report describes the results of a series of recent experiments designed to investigate the nature of the BiF production mechanism and the efficiency with which the electronic energy of NF is converted to BiF(A-X) photons. We have examined the time behavior of three key species resulting from excimer laser initiated reactions of NF2/Bi(CH3)3, NF2/Bi(CH3)3/H2, and NF2/Bi(CH3)3/HBr mixtures. (JS)
