天然丰度碳13核磁共振所有的葡萄糖二糖和四个选定的葡萄糖三糖在水溶液中的光谱已被测量和讨论。根据甲基吡喃葡萄糖苷、四种单-O-甲基葡萄糖和五种甲基葡萄糖苷的光谱比较，进行了峰归属。碳-13 n.m.r.光谱学被证明是用于这些寡糖的立体化学表征的有用工具。此外，碳-13核磁共振。测定了糖原和支链淀粉的β-极限糊精的光谱，并讨论了它们之间的差异。
Natural-abundance carbon-13 n.m.r. spectra of all the glucobioses and of four selected glucotrioses in aqueous solution have been measured and are discussed. Peak assignments were made on the basis of comparison with the spectra of methyl glucopyranosides, four mono-O-methylglucoses and five methyl glucobiosides. Carbon-13 n.m.r. spectroscopy proved to be a useful tool for stereochemical characterisation of these oligosaccharides. In addition, carbon-13 n.m.r. spectra of the β-limit dextrins from glycogen and amylopectin have been measured and the differences between them are discussed.
