Abstract Carbon‐13 NMR signals were assigned for the complete set of the 26 theoretically possible isomers of methyl 5β‐cholanates having one to three hydroxy groups at positions C‐3, C‐7 and/or C‐12 in the nucleus. Substituent effects on the 13 C NMR shielding data serving to characterize the position and configuration of the hydroxy groups are discussed.
