摘要：

Vibrational Raman optical activity (ROA) spectra measured in backscattering covering from 600 to 1600 cm-1 of 15 monosaccharides in aqueous solution are reported which carry signatures from the central features of monosaccharide architecture. Most of the ROA bands in this range appear to be generated by short-range interactions and so reflect local stereochemical details. Three main regions are apparent: approximately 750-950 cm-1, containing information about anomeric configuration; approximately 950-1200 cm-1, showing ROA band fingerprints characteristic of the ring structure and the pattern of substituents; and above approximately 1200 cm-1, dominated by CH2 and C-O-H deformations and reflecting the conformation of an exocyclic hydroxymethyl group.
