The Dependency of Diffusion Coefficients and Geometric Factor on the Size of the Diffusing Molecule: Observations for Different Clay-Based Materials

Table 8

Ratios between the experimentally determined (values see Table 4) and the fitted (using the fits given in Table 6), as well as the averages for each element. Due to the deviating value of He for sample OPA1, the corresponding is not included in the average.
