Recent methodological progress in pulsed field gradient (PFG) NMR and quasi-elastic neutron scattering (QENS) is exploited to enhance the range of diffusion measurement of the series of the n-alkane homologues in MFI-type zeolites (silicalite-1, ZSM-5) up to n-tetradecane. As observed already for th

Results of the first pulsed field gradient (PFG) NMR studies of hydrogen diffusion in zeolites are presented and compared with corresponding measurements by quasielastic neutron scattering (QENS). The results of the two techniques were in satisfactory agreement. Similarly as with other probe molecul
Deuteron NMR relaxation methods including double quantum filtered (DQF) spectral analyses were examined to study the dynamics of benzene molecules adsorbed in faujasite-type zeolite. To describe the dynamics of benzene molecules, a modified cone model involving in-plane rotation, wobbling motion and
Published kinetic and equilibrium data for the sorption of ethane in various cationic forms of type A zeolite are discussed and interpreted in comparison with experimental data, obtained by the authors, for the SA Linde zeolite. It is shown that the equilibrium data for all the zeolites can be corre
