✦ Synopsis

Gentiobiose octaacetate, a disaccharide molecule, was investigated in order to define (i) the proton and carbon assignments and chemical shift values, (ii) the carbon relaxation behaviour in DMSO solution and (iii) the dynamic properties of the molecule. It was found that in solution it behaves like a rigid molecule characterized by an unique isotropic correlation time. Scalar coupling constant analysis allowed the identification of the H-6 axial and H-6 equatorial protons for both sugar ring moieties.
