在量子电动力学（QED）模型的背景下，电子耦合，光谱线宽，和发色团之间的电子能量转移率之间的相互作用进行检查。QED框架适当地允许我们识别近区和远区之间的分区机制，用于分散在凝聚相（液体或固体）宿主介质中的发色团之间的能量转移。耦合被修改的介质的程度进行了研究。一个一般的QED治疗更高的多极贡献之间的耦合过渡时刻也来自，其中涉及电偶极子，四极和八极以及磁偶极子和四极相互作用的相互作用明确检查。提出了一种新的配方，其中多极耦合张量的表达式获得的球形贝塞尔函数，提供了一个清晰，紧凑的表示延迟耦合相互作用及其距离依赖性。不可约张量公式.
The interplay between electronic coupling, spectral linewidth, and rate of electronic energy transfer between chromophores is examined in the context of a quantum electrodynamical (QED) model. The QED framework properly allows us to identify the partitioning between the near and far zone mechanisms for transfer of energy between chromophores dispersed in condensed phase (liquid or solid) host media. The extent to which coupling is modified by the medium is investigated. A general QED treatment of higher multipole contributions to the coupling between transition moments is also derived, whence interactions involving electric dipole, quadrupole and octopole as well as magnetic dipole and quadrupole interactions are examined explicitly. A new formulation is presented wherein expressions for the multipolar coupling tensors are obtained in terms of spherical Bessel functions, providing a clear, compact representation of the retarded coupling interaction and its distance-dependence. The irreducible tensor formu...
