The concentration dependence of solvent self‐diffusion coefficients is examined near the pure solvent limit. It is shown that it is possible to explain an apparently anomalous concentration dependence for the solvent self‐diffusion coefficient at high penetrant mass fractions within the framework of the free‐volume theory of transport.
