چکیده انگلیسی
Magnetic field effects (MFEs) of the radical pairs on the reaction of the photoexcited 2-methyl-1, 4-naphthoquinone in two sodium alkyl sulfate micelles (SDS and SDeS) were investigated under magnetic fields below 1.7 T by a nanosecond laser flash photolysis technique. The result showed that MFEs on the decay of radical pairs and yields of escaped radicals in SDeS micellar solution were saturated at lower magnetic field than in SDS micellar solution. Such saturation could be qualitatively interpreted by relaxation mechanism. Peculiar MFEs on the second chemical and physical process were found for the first time in SDeS micellar solution.
