High resolution 13C-n.m.r. spectroscopy of 'mixed linkage' xylans

Three xylan fractions, obtained by stepwise precipitation with ethanol, were analysed by 75-MHz 13C-n.m.r. spectroscopy. Diad frequencies, determined from the C-2 resonances, show that the (1 → 3)-linkages are interspersed throughout the chain rather than grouped contiguously. This type of distribut...
