Abstract
The rate constants for XeF(B,C), XeCl(B,C), and XeI(B,C) formation from reactions of Xe(3P1) and Xe(3P2) with NF3, N2F4, NF2, CCl4, and CF3I have been measured relative to XeCl(B,C) formation from the reactions with Cl2. The XeCl(B,C) formation rate constants from Cl2 are assumed to equal the total Xe(3P2) and Xe(3P1) quenching rate constants. The dependence of the XeX* formation rate constants upon reagent for Xe(3P1) and Xe(3P2) are similar with the polyatomic reagents having considerably smaller XeX* product formation rate constants than does Cl2. The previous claim from this laboratory that the XeF(B,C) formation rate constant from NF3 was approximately equal to the total quenching rate constant is revised downward in this work.
