✦ Synopsis

Methyl radical reactions with matrix molecules in glasses C2H50H, (CH20H)z, n-and i-C3H70H, n-and i-C4HsOH, n-and i-CSHIlOH, C~DSOH, and i-C:+D70D, and the reactions of C:2H5, C3H7, C4H9, C : ~H I ~ with methanol glasses have been studied. Alkyl radicals were produced by photolysis of diphenylamine-alkylhalide-alcohol mixtures using ultraviolet light.

In all cases the alkyl radical decay follows the law c = c g exp(-h 4). The 4 law should not be associated with alkyl radical diffusion in a matrix. A method of processing the kinetics of those reactions in which one paramagnetic species changes into another with the total concentration being constant and the electron spin resonance spectra of both species overlapping, is described.

The kinetics of the reaction CH3 + 0 2 (+M) -+ CH302 (+MI have been studied, using the technique of flash photolysis and kinetic spectroscopy to follow the methyl radical concentration. The order of the reaction lies between 2 and 3 throughout the range of pressure from 25 to 380 torr at 22"C, and t
