Abstract
The mechanism and kinetics of energy transfer from highly excited Xe states (E ex > 9.5 eV), generated by a 12-ns electron beam, to chlorine donor molecules were deduced from time-resolved spectra of fluorescence in the region 240–340 nm. The emissions at 240–250 nm were assigned to Xe2** excimers, and those at 308 and 340 nm to XeCl(B) and XeCl(C) states. Kinetic analysis of the recorded spectra for Xe–CCl4 and Xe–SOCl2 gas mixtures at constant xenon pressure and various pressures of molecular admixtures (0.1–1 Torr) allowed us to find the rate constants for the reactions (5) Xe** + RCI → products, (6a) Xe** + RCl → XeCl(B) + R*, and (6b) Xe** + RCl → XeCl(C) + R*, where R is any radical.
