Zusammenfassung

The magnetic-field-dependent kinetics of geminate radical pairs, created by electron transfer from aneline to thionine triplet in reversed micelles has been studied by nanosecond laser flash spectroscopy. Depending on the water concentration, the rate constant of intramicellar recombination is reduced by a factor between 2.4 and 3.2 in a field of 1 T. The B1/2 values increase from about 15 to 48 mT when the water-pool radius is increased by a factor of 4. The experimental results demonstrate that triplet-singlet transitions cannot be rate determining in zero field. However, T± → To and T± → S radical pair spin relaxation must become rate determining as the magnetic field is increased above 10 mT.
