The rate constant for the combination of trichloromethyl radicals in the gas phase has been measured by applying the rotating sector technique to the gas phase carbon tetrachloride–cyclohexane photochemical system. A temperature‐independent rate constant, k 5 , of 3.9 ± 1.0 × 10 12 cc mole −1 sec −1 was found. Arrhenius parameters for the reaction\documentclass{article}\pagestyle{empty}\begin{document}$${\rm CCl}_{\rm 3} + c - {\rm C}_{\rm 6} {\rm H}_{{\rm 12}} \mathop {\hbox to 30pt{\rightarrowfill}}\limits^{k_4 } {\rm CHCl}_{\rm 3} + c - {\rm C}_{\rm 6} {\rm H}_{{\rm 11}} $$\end{document}were found to be given by the expression log k 4 = 11.79 – (10,700/2.3 RT ).
