The coefficient of mutual diffusion and the two coefficients of self- diffusion of aqueous solutions of sucrose from 0 to 2.5 M were measured at 25 deg C. The results indicate that the self-diffusion is caused, in part, by the water - water and sucrose - sucrose exchange, and also to the water- sucrose exchange which contributes, at the same time, to the self-diffusion and the mutual diffusion. The tests on the movement of the stable or marked particles have given supplementary proof of the nature at a short distance'' of the coupling between the three types of molecular movement. The actual theories of coupled diffusion are briefly discussed, and another theory based on the theory of absolute velocities is suggested. The coefficients of diffusion of O/sup 18/ and of hydrogen are given at 25 deg C for the whole scale of H/sub 2/OD/sub 2/O mixtures. It is interesting to note that when the diffusion of O/sup 18/ varies in a direction opposite to the viscosity of the mixture, that of the hydrogen shows a prounced minimum for 50% D/sub 2/O. This is interpreted existence of distinct mechanisms for the movements of oxygen and hydrogen, with different exchange phenomena between the groups of water molecules. (tr-auth)
