Experimental results for optically controlled electron-transfer reaction kinetics (ETRK) and nonequilibrium solvation dynamics (NESD) of Coumarin 480 in DMPC vesicle show their dependence on excitation wavelength λex. However, the celebrated Marcus theory and linear-response-theory-based approaches for ETRK and NESD, respectively, predict both of the processes to be independent of λex. The above said lacuna in these theories prompted us to develop a novel theory in 1D space, where the effect of innumerable Franck–Condon states is included through λex. The present theory not only sheds light on the origin of failure of the existing theories but also gives the correct trend for the effect of λex on ETRK and NESD. More importantly, the calculated results of NESD are in excellent agreement with the experimental results for different values of λex. The new theory will therefore advance the knowledge of scientific community on the dynamics of photoinduced nonequilibrium processes.

光学控制的电子转移反应动力学和溶剂化动力学:弗兰克–康登状态的影响

香豆素480在DMPC囊泡中的光控电子转移反应动力学(ETRK)和非平衡溶剂化动力学(NESD)的实验结果表明,它们依赖于激发波长λex。然而,著名的Marcus理论和基于线性响应理论的ETRK和NESD方法分别预测这两个过程都与λex无关。上面说的空隙在这些理论促使我们开发的一维空间,如果国家通过λ包括无数的弗兰克-康登的作用的新理论。本理论不仅阐明了现有理论的失败根源,而且给出了λex效应的正确趋势。在ETRK和NESD上。更重要的是,NESD的计算结果均符合λ的不同值的实验结果非常吻合。因此,新理论将促进科学界对光致非平衡过程动力学的认识。
