A quantum-classical model of photoisomerization of the visual pigment rhodopsin chromophore is proposed. At certain (and more realistic) parameter value combinations, the model is shown to accurately reproduce a number of independent experimental data on the photoreaction dynamics: the quantum yield, the time to reach the point of conical intersection of potential energy surfaces, the termination time of the evolution of quantum subsystem, as well as the characteristic low frequencies of retinal molecular lattice fluctuations during photoisomerization. In addition, the model behavior is in good accordance with experimental data about coherence and local character of quantum transition.
提出了视觉色素视紫红质发色团光异构化的量子-经典模型。在某些（更现实的）参数值组合下，该模型被证明能够准确再现关于光反应动力学的一些独立实验数据：量子产率、到达势能面锥形交叉点的时间、量子子系统演化的终止时间，以及光异构化过程中视网膜分子晶格波动的特征低频。此外，该模型的行为与关于量子跃迁的相干性和局部特征的实验数据高度吻合。
