Collisional deactivation studies of the XeF* (B) state by He, Xe, NF3, and F2

Abstract
Measurements of the rates of quenching of XeF* (B) by He, Xe, NF3, and F2 are reported in this paper. Photolyzing XeF2 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 cm6 sec−1) supports the existence of the trimer Xe2F*. Also, for a given pressure, NF3 quenches XeF(B) ∼13 times slower than does F2.
