Abstract:
The density-matrix equations, as formulated by N. R. Krishna and S. L. Gordon (J. Chem. Phys. 58, 5687 (1973)) for a binary solution are considered, taking into account intermolecular scalar coupling of the first kind as the main relaxation process. The enhancement factor for the intermolecular Overhauser effect is obtained using the nonviscous liquid approximation. This factor results in the opposite sign to that obtained when the only relaxation mechanism considered is the intermolecular dipole-dipole interaction even for strongly coupled spin systems. Since these two are the only interactions which are capable of showing any intermolecular Overhauser effect, this difference in sign obtained for the enhancement factor provides a unique possibility for determining which mechanism is prevailing in a given binary system. An intermolecular Overhauser experiment made by the INDOR procedure is considered. © 1984.
