| Abstract: | The rate constant for the title reaction was found to be (5.72 ± 0 30) × 10?11 cm3 molecule?1 s?1. Fluorine atoms were generated via IR multiphoton dissociation of SF6 in a mixture of CH4, D2, and Ar. The time-dependent concentration of fluorine atoms, and hence the rate of reaction, could be monitored either by HF IR luminescence or by DF luminescence. We have thus established that real-time observation of competitive kinetics can be used to measure a variety of reaction rates. |
