在这项工作中，我们推导出了与一对超出波函数重叠的分子之间的共振能量转移（RET）过程相关的量子振幅的公认表达式。这项工作的新奇在于，介导光子的场被描述为球面波而不是平面波。场的角分量用矢量球谐函数表示，径向分量用汉克尔函数表示。这种方法解决了平面波推导中必须从非物理解中选择物理正确解的问题。球坐标系允许人们容易地将光子场分解成纵向和横向分量，并提供了一种自然的方式来分析近区、中间区和远区RET，这是在两个分子的跃迁偶极矩的相对取向的背景下进行的。
In this work, we derive the well-established expression for the quantum amplitude associated with the resonance energy transfer (RET) process between a pair of molecules that are beyond wavefunction overlap. The novelty of this work is that the field of the mediating photon is described in terms of a spherical wave rather than a plane wave. The angular components of the field are constructed in terms of vector spherical harmonics while Hankel functions are used to define the radial component. This approach alleviates the problem of having to select physically correct solution from non-physical solutions, which seems to be inherent in plane wave derivations. The spherical coordinate system allows one to easily decompose the photon's fields into longitudinal and transverse components and offers a natural way to analyse near-, intermediate-, and far-zone RET within the context of the relative orientation of the transition dipole moments for the two molecules.
