## Abstract Carbon‐13 NMR spectral data for a series of symmetrical 2,6‐disubstituted adamantanes (O, CH~2~, CH~3~, OH, OCOCH~3~) are presented. The substituent effects on ^13^C chemical shifts are additive, except for carbons 2 and 6 in 2,6‐adamantanedione. The non‐additivity of the substituent
## Abstract Carbon‐13 chemical shifts of fourteen __para__‐substituted benzylbenzenes have been determined. The relative substituent chemical shifts (SCS) of the methylene carbons and the aromatic ring carbons (C‐4, C‐1′ and C‐4′) correlated well with the Hammett substituent effects using the dual
## Abstract ^13^C NMR spectra of six epimeric substituted 4‐hydroxypiperidines and two corresponding piperidines were recorded. Substituent parameters for equatorial methyl, __gem__‐dimethyl, equatorial hydroxy and axial hydroxy groups were calculated from the ^13^C chemical shifts of these compoun
