将论文 I（前一篇论文）中开发的分子系统的多极形式应用于分子对，以计算能量转移速率和分子间势能。在这些计算中，当其中一个分子置于另一个分子的麦克斯韦场中时，该分子被视为被动分子。电磁场是使用海森堡图片计算的，如论文 II（前第二篇论文）中所示。对于相同分子之间的共振转移，考虑一阶场就足以获得 F\"orster 速率。对于不同的分子，利用海森堡场可以找到作为时间函数的激发转移概率。色散能计算的一个值得注意的特点是，利用电磁场，校正跃迁矩中的二次项，通过考虑一个分子作为测试极化体，可以获得完整的卡西米尔-波尔德分子间势能。对方的领域。
The multipolar formalism for a system of molecules developed in paper I (first preceding paper) is applied to a molecular pair to calculate the rate of energy transfer and intermolecular potential energies. In these calculations, one of the molecules is treated as passive when placed in the Maxwell field of the other. The electromagnetic field is calculated with the use of the Heisenberg picture as in paper II (second preceding paper). For resonance transfer between identical molecules, it is sufficient to consider the first-order fields to obtain the F\"orster rate. For nonidentical molecules, the probability of excitation transfer as a function of time is found with the use of the Heisenberg fields. A noteworthy feature of the calculations of dispersion energy is that with the use of electromagnetic fields, correct to quadratic terms in the transition moments, the complete Casimir-Polder intermolecular potential energy can be obtained by the consideration of one molecule as a test polarizable body in the field of the other.
