摘要

Simple proximity relationships and relative stereochemistries of substituents in natural and synthetic organic molecules are routinely deduced from'H NMR coupling constants. The verification of distant intramolecular relationships frequently requires the measurement of nuclear Overhauser enhancements,'V2 TI relaxation times, 2 or lanthanide-induced chemical shift change^.^ A recent report by Bax et aL4 showed that small couplings could ...
