A method to distinguish the 5ŕ- from the 5á-isomers of 3-oxosteroid based on lowfrequency 1 H NMR spectra was proposed. Additional 1 H and 13 C NMR characteristics were derived from the comparison of completely assigned spectra of the 5ŕ- and 5á-isomers. The effect of substitution at different positions of steroid skeleton was evaluated on a series of isomeric 3-oxosteroids.
