Additive Effects on the CIDNP, Cage Effect, and Exit Rate of Micellized Radical Pairs

摘要

The effects of additives on the recombination efficiency and exit rates of micellized benzyl radicals have been studied by steady-state CIDNP, steady-state product analysis, and time-resolved optical absorption techniques. The results indicate that the efficiency of triplet geminate pair recombination increases monotonically as the micellar volume increases. Aggregation numbers of SDS micelles were deduced as a function of additive concentration from CIDNP measurements and were found to be consistent with literature values.
