Rates of reactions of azide radical with fluorine, chlorine, bromine, and hydrogen atoms

Abstract

The room temperature rate constant of the reaction F+N 3 →NF+N 2 has been determined by monitoring the time dependence of laser-induced fluorescence from the intermediate N 3 radicals in the presence of a large excess of F atoms. Experiments were performed with CF 4 , SF 5 , and F 2 as precursors of the F atoms. The results indicate that the F+N 3 rate constant is (5.8±0.6)×10 -11 cm 3 s -1 at 298 K
