It has been reported that characteristic IR absorption bands of steroid 5, 6-oxides are observed at 10351050cm-1 and 870875cm-1. IR spectra of cholesterol-α-oxide, its acetate, cholesterol-β-oxide, its acetate, cholestan-3β, 5α, 6β-triol, its triacetate, stigmasterol-5, 6α-oxide, its acetate and stigmast erol-5, 6β-oxide acetate ware compared. As a result, the above absorption bands at 10351050cm-1 and 870875cm-1 were also.observed in the spectra of the triol and triacetate. It was observed that characteristic absorption bands of sterol 5, 6-oxides were 685690cm-1 (α, β;3-OH, 3-AcO), 716720cm-1 (α, β;3-AcO), 748752cm-1 (α;3-OH, 3-AcO), 784786cm-1 (β;3-OH, 3-AcO) and 798cm-1 (α, 3-OH).
