Nuclear magnetic resonance spectroscopy: 13C spectra of unsubstituted inositols.
The chemical shifts of (13)C in natural abundance have been obtained from nuclear magnetic resonance spectra of scyllo-, myo-, chiro-, and epi-inositols at 15.1 MHz. A set of empirical substitutent parameters were derived and shown to be moderately successful in correlating the (13)C resonance-line positions for these substances. The substituent parameters conform generally to the idea that steric hindrance or porximity effects are of special importance in influencing chemical shifts of carbons in cyclohexane systems.
