Diffusion coefficients of gases in R-BAPB at temperature T = 300 K, obtained in molecular dynamics simulations (shaded columns) and in the experiment (solid columns). Semi-logarithmic axes. The error bars denote standard deviation (see main text for details). The diffusion coefficient of N2 lies in the range (0.007 ÷ 0.09) × 10−3 nm2/ns, with 0.02 nm2/ns being the value given by the approximation line.
