Arguments for the applicability of absolute rate theory to molecular transport in zeolites are given. Its application to self-diffusion of methane and ethane in 5A zeolites provides satisfactory coincidence with experimental (n.m.r. pulsed field gradient technique) data in both the absolute values and the concentration dependence. A rigorous discussion of the influence of rotational barriers in the windows between adjacent supercages is presented.
