The concept of free volume is used to describe self-diffusion in liquids. It is found that for different organic liquids (including chloroform, carbon tetrachloride, p-xylene, o-xylene, toluene, n-hexane,

Diffusivities measured at 25ยฐC are reported for ethane in normal hexane, heptane, octane, dodecane and hexadecane, and at 25ยฐC and 50ยฐC for carbon dioxide in hexadecane. Measurements were made by means of the steady-state capillary cell technique. The general relation between diffusivities in dilute
The problem of calculating the diffusivities of gases in molecular sieves from experimental sorption curves is discussed. Commercial molecular sieve pellets contain zeolite crystallites of various sizes and it is shown that both the shape and the size distribution of the crystallites have significan
## Abstract Effects of molecular size and configuration on hindered diffusion were examined by measuring diffusion of two series of uncharged macromolecules through trackโetch membranes with uniform and wellโdefined pore geometry. At any given StokesโEinstein radius, diffusivities in small pores we
