The 1 H and 13 C NMR signals of cyclohexyl phenyl sulphides, sulphoxides and sulphones were almost completely assigned, and the effects of diastereotopism in cis ‐4‐ tert ‐butylcyclohexyl phenyl sulphoxide were rationalized. Substituent effects on the 17 O chemical shift of numerous sulphoxides and sulphones are discussed. An unusual paramagnetic γ gauche effect on the 33 S nucleus was detected in cis ‐4‐ tert ‐butylcyclohexyl phenyl sulphone.
