For intramolecular electron transfer reactions in solution,the fluctuations of the intramolecular vibrational modes are much faster than that of solvent mode.Thus,the reaction-diffusion equation is commonly used to describe the motion of solvent,with a sink function to treat the vibrational high-frequency mode.Based on this theory-so -called the Sumi-Marcus theory,we proposed an imaginary-time split operator approach to solve the reaction-diffusion equation.The approach is applied to evaluate the intermolecular ET rate between oxazine 1 and N,N-dimethlaniline.By measuring the two average survival times of the donor state probability and the rate constant in long time limit,the full kinetics of the ET is revealed with a variety of sink functions.

对于扩散控制的溶液中的电子转移反应,分子内振动模的运动比溶剂运动快很多,Sumi-Marcus理论提出用反应扩散方程(reaction-diffusion equation)处理溶剂的扩散运动,而分子内的振动用sink函数来表示,我们基于此理论发展了用虚时间分裂算符的方法(imaginary-time Split operator approach)解反应扩散方程,并将其应用于嗪1(oxazine 1,OX1)和N,N-二甲基苯胺分子之间的电子转移反应,Sink函数采用几种不同的微扰表达式,通过计算得到给体几率衰减的两种平均速率和长时间极限下的速率常数,揭示了该体系电子转移过程中的一些动力学性质。
