Chemically-Produced N2(A) to NO(X) Energy Transfer in a Supersonic Flow.

Abstract

A supersonic nozzle has been used to produce N2(A) by the reaction of NF2 and H. The NO has been added to the flow via a hypersonic wedge. Excited state NO has been observed from energy transfer. The importance of showing chemically-produced N2(A) transfer of energy to NO is for possible use as a purely chemical ultraviolet laser. The densities observed here are not sufficiently high for use as a laser; however, these experiments indicate that in principle the transfer occurs with good efficiency in a chemical system. Keywords: Nitrogen fluoride, Excited nitrogen, Metastable nitrogen, Energy transfer, Chemical laser.
