摘要: 用时间分辨电子自旋共振(TRESR)波谱仪研究了光解蒽醌自由基的化学诱导动态电子极化(CIDEP).实验测量表明,在蒽醌/乙二醇/TX-100体系中,蒽半醌自由基AQH·有很强极化ESR信号,在激光激发后~0.8μs,检测到蒽醌负离子基AQ·-的信号,表明AQH·自由基部分地离解为负离子基AQ·-.

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·-.
