Abstract

Bromine monofluoride (BrF), an interhalogen molecule, is a prospective chemical laser candidate. This study continues research begun in characterizing radiative and collisional dynamics in BrF. Vibrational energy transfer of BrF is studied using time resolved laser induced fluorescence (LIF) techniques and observing the spectrally resolved emission. First, vibrational transfer induced by the BrF production mix is determined to follow the Montroll- Shuler model and Landau-Teller scaling with a fundamental rate coefficient of kv(1,0) = (4.0) x 10^-12 cm³/(molecules seconds). Also, rate coefficients for the rare gases were found to scale with the reduced mass of the collision partner, as predicted by the Schwartz, Slawsky and Herzfeld (SSH) theory with values ranging from (3.9) x 10^-12 cm³/(molecules x seconds) for helium to (2. 2) x 10^-13 cm³/(molecules x seconds) for xenon.
