Abstract
Valence bond theory, Dirac's vector model, and a perturbation calculation express the coupling constant between nuclear spins as a function of exchange integrals. The approximation of mean excitation energy is not utilized. The singlet states are represented by the product of singlet functions of two electrons in one bond, or singlet functions of four electrons in two bonds, while the triplet states are represented by the product of one triplet function of two electrons in one bond, and of the preceding singlet functions. The different transfer processes of the excitation from a nucleus to the other in the molecule are given.
