Ring 'H and I3C NMR chemical shifts for 14 aldopyranoses were measured in D,O and dimethyl-d, sulphoxide; those for eight aldofuranose monosaccharides were measured in dimethyl-d6 sulphoxide. The effects of solvent are small. Shifts can be predicted with reasonable accuracy using algorithms having a
