摘要：

Magnetic field effects on the photodissociation reaction of triphenylphosphine at 293 K were investigated in several non-viscous homogeneous solvents by means of a nanosecond laser photolysis technique under magnetic fields of 0-1.75 T. The generated neutral radical pair of the diphenylphosphinyl and phenyl radicals showed clear magnetic field effects. The yield of the escaped diphenylphosphinyl radical at 1.5 T reduced to 74% +/- 3% of that at 0 T in 2-propanol (eta = 2.379 at 293 K). Similar magnetic field effects were observed at 293 K even in more fluid solvents such as n-hexane (84% +/- 5% at 1.5 T), cyclohexane (65% +/- 2% at 1.5 T), and p-dioxane (64% +/- 3% at 1.5 T).
