摘要: 报道了用时间分辨电子自旋共振波谱仪对吩噻嗪与对苯醌的乙二醇溶液体系的紫外光照过程进行实时检测,从测得的电子自旋共振极化港可知,电子转移和质子转移在光照过程中同时存在并且相互竞争.

关键词: 电子转移, 质子转移, 自由基, ESR, CIDEP

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.

Key words: Electron transfer, Radical, ESR, CIDEP
