## Abstract ^13^C NMR spectra of six epimeric substituted 4βhydroxypiperidines and two corresponding piperidines were recorded. Substituent parameters for equatorial methyl, __gem__βdimethyl, equatorial hydroxy and axial hydroxy groups were calculated from the ^13^C chemical shifts of these compoun
In the present work, a theoretical analysis was carried out on the effect of the proximity of a polar bond to a polarizable bond on the magnetic shielding constants of the nuclei belonging to the polarizable bond. In particular, the case of 13 C magnetic shielding constants in a vinylic C C bond is
