The magnetic field effect on the hydrogen abstraction of xanthone from xanthene, 9,10-dihydroanthracene, and sodium dodecyl sulfate (SDS) surfactant has been studied in SDS micellar solution by steady-state (= 260 mT) and laser flash photolysis (= 80 mT).In the steady-state photolysis, the relative quantum yield of the disappearance of xanthone decreases in the magnetic field.Transient absorption intensities of 9-xanthenyl and 9,10-dihydroanthracene-9-yl radicals in the laser flash photolysis show remarkable magnetic field dependence, when xanthene and 9,10-dihydroanthracene are used as the respective hydrogen donors.All the results are interpreted in terms of the radical-pair model.
