✦ Synopsis

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 of a polycrystalline sample of that compound. The differences between the r3C chemical shifts observed in the c.p.-m.a.s. spectrum of the solid and of solutions of methyl a+u-glucopyranoside are discussed in terms of the different types of hydrogen bonds formed in the crystalline state and in solution.
