推导了描述由两个相同分子形成的二聚体的电子振动状态的哈密顿量。假设单体单元仅通过共振力耦合并且在基态和激发态具有不同的平衡位置。这两种效应的竞争是用数学公式表示的。当共振力占主导地位时，会出现强耦合情况；当平衡位置变化的影响占主导地位时，就会出现弱耦合情况。
The Hamiltonian describing the vibronic states of a dimer formed by two identical molecules is derived. The monomeric units are assumed to couple by resonance forces only and to have different equilibrium positions in the ground and excited states. The competition of these two effects is formulated mathematically. The strong coupling case occurs when the resonance forces dominate; the weak coupling case arises when the effect of the change of equilibrium positions dominates.
