The configurational and conformational assignments of the carbonyl group in the Z ‐ and E ‐1‐(3‐substituted‐5,5‐dimethyl‐2‐cyclohexen‐1‐ylidene)‐2‐butanones are carried out using only the through‐space effects of the carbonyl group. It is demonstrated that, regardless of the Z ‐ or E ‐configuration or the nature of the substituent in position 3, the conformation of the carbonyl group is always s ‐ cis .
