In connection with the study of sugars and glycosides by infrared absorption spectra, the present studies and those reported by Whistler and House and by Barker, et al. were compared. It was thereby found that the results of Barker and of the writer agree well but not that of Whistler and the writer. Barker and others concluded that the infrared spectra of the α, β-series of the reducing sugars and methyl-glucosides or polysaccharides made it possible to discriminate between α and β. The present writer made further clarification of this theory and assumed that it might be possible to discriminate the structural difference of cis and trans of the asymmetric C₁ and C₂ carbons in sugars and glucosides.
