All arrangements and procedures for steady-state and time-resolved ESR were as described in [4]. The radicals Me,C and Me3C02CCH, were generated by photolysis of the corresponding disubstituted ketones. These undergo type-I cleavage from a short-lived triplet state followed by a fast decarbonylation
