The lanthanide induced chemical shifts and coupling constants have been determined for ring A protons of steroids having a keto, hydroxyl, or acetate functional group at C‐3. The assignments were made with the aid of suitably deuterated compounds and should prove useful in steroidal stereochemical and conformational studies.
