## Abstract The decay of photochemically generated __tert__βbutyl radicals in methylcyclopentane solutions containing chloroform is studied by timeβresolved ESR spectroscopy. In the pure solvent it perfectly follows the secondβorder rate law for radical selfβtermination. Increasing chloroform conce
