【Abstract】 In this paper, the time-resolved ESR technique has been used to study the photochemical process of phenothiazine and p - benzoquinone in ethylene glycol. From the CIDEP spectra and the thermodynamic calculations, we come to the conclusion that the electron transfer and the hydrogen abstraction proceeded simultaneously and competed with each other during the photolysis.更多还原
