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 COH deformations region above ∼1200 cm−1. In the fingerprint region, ROA signals which reflect the relative orientation of substituents originate primarily in skeletal CC and CO stretch coordinates: COH deformation coordinates also contribute to the parent Raman band intensity but not to the ROA intensity. In the CH2 and COH 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.
