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.
