Complete assignments are presented of the 13C-n.m.r. spectra of the mixtures of methylated D-glucoses and methylated methyl D-glucosides that respectively result from hydrolysis and methanolysis of commercial samples of O-methylcellulose. The effects of methylation on the 13C chemical shifts of some

The effects of O-carboxymethylation at each of positions 2, 3, and 6 on the 13C chemical shifts of glucose have been used to assign first the 13C-n.m.r. spectra of 2,3-, 2,6-, and 3,6-di-O-(carboxymethyl)glucose and 2,3,6-tri-O-(carboxymethyl)glucose and then the spectrum of hydrolyzed O-(carboxymet
