Abstract

Abstract: The chemically induced dynamic electron polarization (CIDEP)of the photolysed anthraquinone radicals was studied by using the time-resolved ESR spectrometer.The strong polarization signal of anthrasemiquinone radical AQH· was obtained experimentally in the anthraquinone/ethyleneglycol/TX-100 system.The polarization signal of the anthraquinone anion radical AQ·^- was measured after laser excitation ~0.8μs. This fact indicates that the anthrasemiquinone radical was dissociated partially to the anthraquinone anion radical AQ·^-.

Key words: Time-resolved ESR, CIDEP, Photolysed anthraquinone radical, Surfactant
