Abstract

Vibrational Raman optical activity (ROA) spectra in back-scattering from 600 to 1600 cm−1 of d-glucose, d-glucose-1-d, d-glucose-6,6-d2, d-glucose-O-d5, t-thio-d-glucose, and d-glucosamine hydrochloride are reported. Prominent signals for d-glucose appear in the region above ∼950 cm−1 and can be subdivided into a fingerprint region from ∼950 to ∼1200 cm−1, and a CH2 and COH deformations region above ∼1200 cm−1. In the fingerprint region, ROA signals which reflect the relative orientation of substituents originate primarily in skeletal CC and CO stretch coordinates: COH deformation coordinates also contribute to the parent Raman band intensity but not to the ROA intensity. In the CH2 and COH deformations region, negative and positive ROA bands appear at ∼1220 and ∼1260 cm−1, which may be attributed to the gauche-gauche and gauche-trans rotamers of the exocyclic hydroxymethyl group, respectively. The ∼1260 cm−1 ROA signal also reflects the anomeric configuration since only the β anomer generates an ROA signal at this wavenumber.
