Abstract
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
were found to be given by the expression log k~4~ = 11.79 – (10,700/2.3 RT).
