Abstract

Measurements of the rates of quenching of XeF*(B) by He, Xe, NF ₃, and F₂ are reported in this paper. Photolyzing XeF ₂ in the presence of the desired diluent gas resulted in the single-step, collisionless formation of XeF*(B), allowing exponential decay studies of the B state population to be made. The large three body quenching rate measured for xenon (∼2.4×10^-29 cm ⁶sec^-1) supports the existence of the trimer Xe ₂F*. Also, for a given pressure, NF₃ quenches XeF(B)∼13 times slower than does F₂.
