Assuming an ionic-like interaction potential between the framework atoms and cations, Smirnov et al. performed an MD study to assess the cation dynamics in zeolite A. The calculation of the power spectra for Na" and cations at each site revealed that no specific spectral pattern can be attributed to a particular cation position. Vibrations of cations in all sites occur over a frequency region of 30-300 cm In addition, the spectra calculated with a flexible framework showed a substantial coupling between the cationic and lattice degrees of freedom. The results of this work °° have brought into question the assignments proposed for the bands in the far-infrared spectra of cationic forms of zeolites.

As for thin films J, = -df (dc /df), (89) and (90) have the same form as the Bruckenstein and Hillman equation (64) when q min is considered to be negligible. For the solvent, the same model as used by Bruckenstein and Hillman (68) is adopted and which has formally the same form as the anion and cation dynamic laws ...
