TLDR
In this paper, the C nmr spectra of some inositols and their partially O-methylated derivatives are tabulated and discussed, and a system of empirical constants which can be used to estimate the spectral properties of the carbons of these ring systems is derived.Abstract:
The ^(13)C nmr spectra of some inositols and their partially O-methylated derivatives are tabulated and
discussed. Methods of assignment are detailed. A system of empirical constants which can be used to estimate
the spectra of the carbons of these ring systems is derived. The substituent effects are noted to conform generally to the notion that steric or proximity effects are very important sources of chemical-shift differences in these systems.read more

NMR spectroscopy of polysaccharide derivatives and their molecular structure. Review
TL;DR: In this paper, the results of experimental investigations to evaluate the reactivity of the hydroxyl groups and the structure of the products in chemical conversions of the polysaccharide chain using high-resolution NMR spectroscopy in its different variants (1H and 13C NMR in solution and 13c NMRI in the solid phase) are reviewed.

Synthesis of Tetrahydrospectinomycin
TL;DR: In this paper, the 1H and 13C NMR spectra were determined and analyzed for tetrahydrospectinomycins, and the compound 11 was found to be identical with one of the four tetrahedrospectrinomycINS.
