The interhalogen molecule, bromine monofluoride BrF, is currently under study as a potential candidate for a visible chemical laser medium. Previous studies have shown a strong emission from BrFB3IIO in the presence of singlet oxygen. While singlet oxygen will pump BrFX to BrFB, the exact mechanism is not known. Chemiluminescence observed from BrFB excited by oxygen in a gas flowtube was used to study the energy transfer mechanism. The objective of this research was fourfold. First, the pumping process was identified as a 3- Body Mechanism. Second, the observed vibrational distribution clearly showed the population of the BrFB state to be non-Maxwellian.
