✦ Synopsis

Metastable electronically-excited NFIZ+, t)' = 0 molecules are produced by the rapid reactions of ground state O(3P), N(4S') and H(2S) atoms with NF2 radicals generated by thermal dissociation of Fi$?4 in a flow system, The IA, v' = 0 state of HP has also been detected from the reactions H+NF2, 0 tNF2 and N+NF2. The rate of decay of NFIZ+, U' = 0 has been determined at 293OK from the rate of attenuation of the intensity of the green emission spectrum (NF1z+-X3C', (I). 0) Q head at 528.8 nm). Assuming no appreciable formation of IB f by energy poolia of two iA molecules, the results are interpreted to show that the radiative lifetime for the NFlx+-X c' transition is 0.2 set, and the rate constant for 5 electronic quenching of NFIZ+ by N2 is 2 X IO-I6 cm3 set-l.
