从随机的角度分析分子系综中电子激发能量的辐射传输（或辐射迁移）。这种方法产生的结果比以前的处理更普遍，其中连续的跳跃被（隐式）假设为不相关，而它们实际上构成了马尔可夫过程。获得分子系响应于外部线偏振且基本上单色光的激发而发射的荧光强度的时间演变。与之前的处理相比，只需要已知的参数。还首次获得了荧光各向异性的时间演化。 (C) 1995 年美国物理研究所。
The radiative transport (or radiative migration) of electronic excitation energy in a molecular ensemble is analyzed from a stochastic point of view. This approach yields results considerably more general than those of previous treatments, where successive hops are (implicitly) assumed to be uncorrelated, while they constitute in fact a Markov process. The time evolution of the fluorescence intensity emitted by the molecular ensemble, in response to excitation by an external beam of linearly polarized and essentially monochromatic light is obtained. In contrast to the previous treatments, only known parameters are required. The time evolution of the fluorescence anisotropy is also obtained for the first time.
