Abstract

When Bromine is combined with flourine atoms and discharged oxygen in a flow tube is produced in a highly non thermal distribution peaking at v'=3. The emission was linearly dependent on the concentration. The observed dependence of the BrF(B) emission on Bromine and atomic oxygen is inconsistent with a steady state prediction of a sequential excitation mechanism, where BrF(X) is excited by successive collisions with singlet oxygen. The experimental data are consistent with a three body mechanism involving Br and F atoms. Electronic quenching of BrF(B) by a number of collision partners (Br2, CO2, O2, N2, CF4, SF6, Ar) was examined for three vibrational levels using laser induced fluorescence (LIF) techniques. Vibrational transfer in BrF(B), induced by the BrF production mix (CF4, Br2, F) was measured by observing the spectrally resolved LIF emission from each vibrational level after an initial excitation of BrF(B) v'=5.
