A complete, unambiguous assignment of all the 13 C signals of cellobiose and maltose has been achieved using methods such as selective proton decoupling, 13 C selective spin labeling, and isotopic chemical shift induced by deuterium. The chemical‐shift variation of the 13 C signals with the degree of polymerization in each α or β (1 → 4) series is discussed. The chemical‐shift dependence on temperature and solvent in these two series is shown and interpreted in terms of modifications of the solvation and of the conformation.
