✦ Synopsis

The kinetics of geminate processes of ground and excited diphenylmethyl radical pairs have been examined in micellar solution using laser photolysis techniques. The radicals do not escape from the micelles in the submicrosecond time scale in which geminate processes-which are controlled by spin evolution -take place. Excited radical lifetimes are 120-140 ns in micellized radical pairs, but become comparable to typical homogeneous values (circa 250 ns) in the presence of magnetic fields. * Issued as NRCC 31525.
