Abstract
The self-diffusion coefficients D for methyl alpha- and beta-D-glucopy ranosides in aqueous solutions have been measured in the concentration range between 10% and 70% (w/w) glucoside in a wide temperature range . At higher concentrations (c greater than or equal to 40%) the mobili ty of the water and the glucoside molecules is significantly lower in the alpha-D-glucoside solutions than in the corresponding mixtures con taining the beta-anomer.
