constraints and electronic factors pertaining to the molecule. The decay kinetics studied using Time Correlated Single Photon Counting showed a bi-exponential decay indicating the involvement of two transient species in the excited state of these molecules. Also, we build up a relation between the rate of the photochemical reaction, free energy change and quenching of excited states.

甲胺的光物理性质。这些化合物的吸收和荧光发射光谱分析表明,分子内光诱导的电子转移导致激发态猝灭,其效率取决于几何约束和与分子有关的电子因素。使用时间相关单光子计数研究的衰变动力学显示出双指数衰变,表明两个瞬态物质参与了这些分子的激发态。此外,我们建立了光
化学反应速率,自由能变化和激发态猝灭之间的关系。
