摘要

THE GENERAL RELATIONSHIP FOR CALCULATING INDIRECT NUCLEAR SPIN SPIN COUPLING CONSTANTS OF 1 J N=N AND 1 J N=C HAS BEEN DERIVED. THE COUPLING CONSTANTS ARE MAINLY AFFECTED BY BOND POLARIZATION AND HYBRIDIZATION OF BONDING ATOMS.THE COUPLING CONSTANTS EVALUATED BY USE OF THESE CONCRETE RALATIONSHIPS ARE IN GOOD AGREEMENT WITH THE EXPERIMENTED DATA.
