Dielectric and far-infrared investigation of cation movements in X-type zeolites. Study of their correlations

Abstract

A study is reported of the correlations between the movements of cations in partially rubidium-exchanged X zeolites. The study shows that electrostatic repulsions between the cations have no influence on the mechanism responsible for the correlations observed with dielectric relaxation. Moreover, by using far-infrared spectroscopy it is possible to infer that these repulsions are weak compared with the cation–framework interactions.
