Abstract The 1 H and 13 C NMR spectra of a range of 1‐, 2‐ and 3‐pheny1, ‐benzyl and ‐phenethyl substituted cyclopentanols and cyclopentylmethyl alcohols and related unsaturated compounds are reported, and assigned using heteronuclear shift correlations. Shift profiles for simple cis ‐ and trans ‐1,3‐disubstituted cyclopentanes are shown to apply also to those with bulkier substituents, and thence stereochemistries can be assigned to isomeric components in mixtures.
