摘要：

Photochemical reactions of triplet xanthone and 2,5-dimethyl-p-benzoquinone with 2-propanol, xanthene, and N,N-diethylaniline in 2-propanol were investigated at 293 K by a nanosecond laser photolysis technique under magnetic fields of 0-10 T. In the reactions with 2-propanol and xanthene hydrogen transfer was found to occur and generated neutral radical pairs showed no or a very small magnetic field effect. On the other hand, electron transfer was found to occur in the reactions with N,N-diethylaniline and the generated radical ion pairs showed fairly large magnetic field effects. Here, reverted magnetic field effects were also observed in 2-propanol like those observed in micellar solutions.
