Hydration of carbohydrates: NMR studies on solute-solute and solute-solvent interaction

摘要

NMR Diffusion-Ordered Spectroscopy (DOSY) allows discrimination among species present in a mixture on the basis of their different translational diffusion coefficient (D_t). Accord ing to the Stokes-Einstein equation (D_t=kT/(6πrη0, k= Boltzmann's constant), D_t values are governed by hydrodynamic radius of a molecule (r) as well as temperature (T) and viscosity of the solution (η0).
