In a recent publication, Mills et al. (1) calculated distinct diffusion coefficients in 4 frames of reference for 14 binary nonelectrolyte mixtures. Because of space limitations, some of the data were represented graphically in that paper. The distinct diffusion coefficient data for the mass-, volume- and number-fixed frames of reference for all systems are given numerically here. The thermodynamic factor (partial derivative ln a(i)lpartial derivative ln x(i))T,P, which is often used in mass-transport theories, is also given.
