Proton chemical shifts for the C-18, C-21, -CO,CH,CH, and -CO,CH,CH, protons of epimeric ethyl esters of 20(R,S)-hydroxy-23-norcholanoic acids were measured in deuteriochloroform and pyridine-d, . The observed solvent shifts due to specific OH-pyridine hydrogen-bonded complexes allowed the quantific
