Abstract

Rate constants for the self‐reaction of __tert__butyl radicals in six __n__alkanes are determined as functions of temperature by kinetic electron‐spin resonance spectroscopy and from rates of product formation. They are well described by a Smoluchowski–Stokes–Einstein treatment including effects of microfriction and spin statistical factors, indicating complete diffusion control. The ratio of disproportionation to combination products is found to depend on temperature and solvent. This is tentatively ascribed to reorientational effects in the encounter pairs.
