✦ Synopsis

The diffusion coefficient of '%r in natural krypton has been measured as a function of density. T'hc results deviate significantly from the values predicted by the Enskog theory. At low densities. the behaviour can be described by regarding the gas as a monomer-dimer mixture.

## Abstract The free‐volume theory of diffusion is used to predict the effect of the glass transition on the concentration dependence of the solvent self‐diffusion coefficient at constant temperature. The theoretical prediction is in agreement with experimental data. Β© 2003 Wiley Periodicals, Inc.
