Abstract
ABSTRACT Experimental 1H NMR chemical shifts were related to results obtained from theoretical calculations, in this case the HSEA approach, in order to obtain information about conformational equilibria about the glycosidic bond of disaccharides. Assuming the existence of the exo-anomeric effect, it was shown that the sign of torsion angle Ψ can be obtained tentatively from the 1H N M R chemical shifts.
