The rate constant for the reaction \documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm CH}_{\rm 3} + {\rm CH}_{\rm 3} + {\rm M}\mathop {\longrightarrow}\limits^{k_1 } {\rm C}_{\rm 2} {\rm H}_{\rm 6} + {\rm M} \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\left( {{\rm M = He}} \right) $$\end{document} has been determined by means of vacuum ultraviolet flash photolysis and time-resolved kinetic spectroscopic observations of the 1504-Å absorption band of CH3. The measurements made using three different sources of methyl radicals (azomethane, dimethylmercury, and ketene-hydrogen) were in accord and yielded a value for the rate constant of k1 = (9.53 ± 1.17) × 10-11 cc molec-1 sec-1. A detailed error analysis is presented. The f-value for the 1504-Å band of CH3 is determined to be (2.5 ± 0.7) × 10-2.
