It is shown that it is possible to obtain good data for the rate constant for the decomposition 01 alkoxy radicals [RO] by using nitric oxide a s a radical trap. Two experimental systems have been used. T h e first system involves the use of dialkyl peroxides [(RO)?] a s thermal sources ofalkoxy ra
Fourier transform infrared spectroscopy was used to identify CH2FOOH and HC(O)F as products of the gas-phase reaction of CHIFOz radicals with HOs radicals. At 700 Torr and 295 + 2 K, branching ratios for the CHrFOOH forming channel, k,,/k, =0.29 f 0.08 and the HC(O)F channel, klb/kl =0.71 f 0.11 wer
Abstrac~Analyses of the rotational diffusion characters of free and bonded nitroxyt radicals in polyvinylacetate were carried out. The radical rotational character essentially depends on the molecular sizes of the radicals. The movement of the "small" radical is matched by the arbitrary jump tumblin
The rate constant for the recombination of trichloromethyl radicals has been measured in the gasphase photozhlori.lation of chloroform at 344.7OK. The observed value is IO9.62mole-Ilsec-I, much lower than the value -u-edicted by transition state calculations using Gorin's model.
