Reactions of the hydroxyl radical, OH, with several reactants have been studied near 1200 K in shock tube experiments in which UV absorption was used to monitor the OH concentration. The values of the rate coefficients were found to be 2.7 x lo", 2.6 X lo", 2.8 x and 1.26 x 1013 cm3/mol-s for the re

β¦ Synopsis
Concentration-time profiles have been measured for hydroxyl radicals generated by the shock-tube decomposition of hydrogen peroxide in the presence of a variety of additives. At temperatures close to 1300"K, the rate constants for the reaction OH + R H + R + HzO arr found to be in the ratio 0.18:0.

The hydrogen transfer reaction between C2H6 and CFs radicals, generated by the photolysis of CF31, has been studied in the temperature range 298-617 K. The rate constant, based on the value of 1013 36 cm3 mo1-l s-' for the recombination of CFs radicals, is given by log kp = (11.90 2 0.09) -(33230 \_
