The chemical shielding tensors and their direction cosines of the "C nuclei in a single crystal of methyl cr-D-glucopyranoside were determined by the high-resolution solid state n.m.r. technique. The results were used to assign the 13C cross-polarization, magic angle spinning (c.p.-m.a.s.) spectrum
