A Direct Kinetic Study of Cl Atom Reactions

[摘要] A non-Boltzman equilibrium population of Cl(2P1/2) atoms has been observed in a flow discharge-atomic absorpion experiment. The rates of reactions of Cl(2P3/2) atoms with various substrates are in reasonable agreement with reported values determined by competition methods. The similar reactivities of both Cl(2Pl/2) and Cl(2P3/2) atoms indicate that the contribution of Cl(2P1/2) atoms to the rate measurements in the competition experiment is small, and this negligible contribution may be the reason why the rate constants obtained by assuming single reactive species (in competition method) agree well with our direct measurement.
