Abstract

The chemical shifts of 13C 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 13C 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.
