Abstract
In order to determine the C–C bondchemical shift in a new series of substituted hydrocarbons, the chemical shifts of the α protons in a series of monosubstituted cyclohexanes have been studied. Where possible each sample was frozen into its individual conformers in order to account for varying stereochemical influences. The derived values of the C–C bond shifts are in good agreement with the values found for corresponding ethyl and isopropyl derivatives.
