## Abstract The rate coefficient for the reaction of CCl~3~ radicals with ozone has been measured at 303 ยฑ 2 K. The CCl~3~ radicals were generated by the pulsed laser photolysis of carbon tetrachloride at 193 nm. The time profile of CCl~3~ concentration was monitored with a photoionization mass spe

Abstract
The kinetics of gammaโradiationโinduced freeโradical reactions in carbon tetrachloride solutions of ethanol and nโpentanol were studied in the range of 0.05โ0.80__M__ and 25โ170ยฐC. The rate constant for the reaction
was found as
The activation energy is larger by 0.8 kcal/mol than for secondary alcohols, while the A~1~ factors are about the same.
