Long-range heteronuclear coupling constants, 3J(C,H), were measured across glycosidic linkages in b-linked disaccharides and also for vicinally disubstituted trisaccharides. One-dimensional multiple-site 13C excitation experiments using Hadamard spectroscopy and band-selective 1H decoupling during t

## Abstract Carbon‐13 NMR spectra of pyridine have been observed by using the slow scan technique in the absorption mode. The long range coupling constants between carbon‐13 and protons have been obtained and assigned by the isotope substitution method.
A m d i e d version of the two-dimensional semiselective INEPT experiment is presented which allows the determination of long-range protowarbon couplings in medium-sized molecules. The difference in the TI relaxation times is utilized for the reduction of the number of protons from which coherence i
