## Abstract The ^13^C NMR spectra of 20 aminocycloalkanecarbonitriles were determined in CDCl~3~. The signals were assigned by a self‐consistent analysis of chemical shift data and comparison with results from phencyclidine analogues. The results were interpreted in terms of changes in the amine (p
## Abstract Fourier transform carbon‐13 nuclear magnetic resonance spectra have been obtained and interpreted for some 2‐substituted tetrahydropyrans. The effects of the substituents on α, β, γ and δ‐carbon atoms are discussed. Using suitable reference compounds the γ‐parameter can be used for quan
