Estimation of diffusion coefficients by using a linear correlation between the diffusion coefficient and molecular weight

► Linear correlation between the diffusion coefficient and the molecular weight. ► The rearrangement of the Stokes-Einstein to estimate diffusion coefficients. ► Estimation of diffusion coefficients in organic solvents. ► Diffusion coefficient data in acetonitrile, dimethylsulfoxide and dimethylformamide. ► The linear correlation between the diffusion coefficient and the molecular weight in DOSY experiments.
