This Letter reports on the application of the vacuum ultraviolet laser-induced fluorescence detection of Br(P-2(1/2)) atoms at 157.48 nm to the kinetic study of collisional removal of Br(P-2(1/2)) by small molecules at 295 K. Gas mixtures of a small amount of CH3Br and an excess amount of collision partners are exposed to pulsed laser irradiation at 193 nm. Temporal decay pro. le of the Br* LIF intensity has been monitored to determine the collisional removal rate coeffficients. The collision partners are H-2, CO2, CF4, CF2H2, H2O, CH3OH, and SF5CF3, and the results are compared to literature data. (c) 2008 Elsevier B. V. All rights reserved.
