提出了一种双色光子回波峰移测量方法，用于探测分子复合物中的电子耦合强度。电子本征态之间的激子转移被忽略，与每个单体相关联的浴被假定为彼此独立。在这个简化的模型中，我们推导出一个有用的关系，它可以用来估计电子耦合强度通过一个正常的单色和目前的双色峰移测量的组合。一个基于累积量展开技术的仿真结果说明了我们的建议的有效性。
A two-color photon echo peak shift measurement to probe the electronic coupling strength in molecular complexes is proposed. Exciton transfer between the electronic eigenstates is neglected and the baths associated with each monomer are assumed to be independent of each other. Within this simplified model, we derive a useful relation which can be used to estimate the electronic coupling strength via a combination of a normal one-color and the present two-color peak shift measurements. A simulation based on the cumulant expansion technique illustrates the validity of our suggestion.
