Nuclear Overhauser effects and the flexibility of saccharides: methyl beta-xylobioside.
The behavior of methyl beta-xylobioside has been analysed by 1H-n.m.r. spectroscopy for solutions in water and methanol in the range - 15 degrees to 85 degrees. Experimental n.O.e. values did not change with temperature and solvent in contrast to the inter-glycosidic 3JC,H values. Experimental n.O.e. data accorded with the values calculated from time-averaged cross-relaxation terms. The tumbling times were determined from relaxation data and were in the sub-ns range.
