摘要：
Proton nuclear magnetic resonance at 500 MHz resolves anomeric proton resonances of dextrans well enough to furnish useful structural information. Minor resonances which would take inordinately long accumulation times to detect by carbon-13 spectroscopy are readily accessible. Enzymic hydrolysis of the dextrans to homologous series of oligosaccharides was useful in assigning anomeric resonances to specific structural features in the polysaccharides. Neighbouring group effects are also discussed. © 1990.
