Abstract

The rate constant for the bimolecular combination of benzyl radicals in cyclohexane and toluene is determined as a function of temperature. Further, it is studied in cyclohexane–toluene mixtures of different compositions. In the entire range covered, 9.8 × 10^8^ ⩽ 2__k__~t~ ⩽ 9.0 × 10^9^M^−1^·sec^−1^, the data are very well described by the Smoluchowski equation for a diffusion‐controlled reaction to ground‐state products using a spin statistical factor of 1/4, a temperature‐ and solvent‐independent reaction distance, and the known diffusion coefficient of toluene.

## Abstract Rate constants for the self‐ and cross‐termination of the isopropylol radical [(CH~3~)~2~ĊOH] and its anion [(CH~3~)~2~ĊO^−^] in aqueous solution are determined by kinetic electron spin resonance. Whereas the self‐termination of the neutral radical occurs close to the diffusion‐controll
