Because the rate of ET and HT reactions is determined by the coupling term J, and in long range ET and HT systems the degeneracy of the π orbitals of donor and acceptor is lifted through mixing with the bridge orbitals of appropriate symmetry by an amount △E. Because the △E splittings are proportional to electronic coupling, so we can use the static quantity △E to exploring the dynamic quantity J, and to make a detailed study on the microscopic influence of coupling mechanism in ET and HT process.

由于电子转移和空穴转移反应速率的大小决定于反应的耦合因子，在长程电子转移和空穴转移体系中，给体和受体的简并π轨道由于与饱和桥之间的TB作用而产生一定的分裂能，此分裂能又与耦合因子的数值成正比，因此，我们可以用静态的分裂能数值间接地表征动态的耦合因子，从而详细研究电子转移和空穴转移过程中耦合机理的微观影响因素。
