Abstract
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: ∼750-950 cm -1 , containing information about anomeric configuration ∼950-1200 cm -1 , showing ROA band fingerprints characteristic of the ring structure and the pattern of substituents; and above ∼1200 cm -1 , dominated by CH 2 and C-O-H deformations and reflecting the conformation of an exocyclic hydroxymethyl group
