Photoinduced intramolecular electron transfer in donor–acceptor systems separated by a long distance are studied by fluorescence quenching experiments; reduced rate constants for electron transfer are observed in highly exothermic reactions, which indicates the existence of an ‘inverted region’, in accord with Marcus' model.
通过荧光猝灭实验研究了在长距离分隔的供体-受体系统中光诱导的分子内电子转移。在高度放热的反应中观察到电子传递速率常数降低,这表明存在“倒置区域”,这与马库斯模型一致。
