✦ Synopsis

A complete, unambiguous assignment of all the 13C signals of cellobiose and maltose has been achieved using methods such as selective proton decoupling, 13C selective spin labeling, and isotopic chemical shift induced by deuterium. The chemical-shift variation of the 13C signals with the degree of polymerization in each (Y or 0 (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.

By means of alkaline extraction of the cell walls of the yeasts Saccharomyces cermisiue and Candida albicans, water-insoluble glucans were obtained. Methylation analysis and 13C-nmr investigation in dimethyl sulfoxide solution revealed the similar chemical structure of these glucans, being composed

## Abstract NMR spectroscopic studies are undertaken with derivatives of 2‐pyrazinecarboxylic acid. Complete and unambiguous assignment of chemical shifts (^1^H, ^13^C, ^15^N) and coupling constants (^1^H,^1^H; ^13^C,^1^H; ^15^N,^1^H) is achieved by combined application of various 1D and 2D NMR spe
