Nuclear Magnetic Resonance Spectroscopy. Carbon-13 Spectra of Some Inositols and Their O-Methylated Derivatives
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
