摘要：

A new approach for retrieving information on cation siting in silicon-rich zeolites like ZSM-5 is presented. It is based on combined investigations using the cation sensitive methods, far-LR spectroscopy and EXAFS together with computer simulations. This combination proved to be successful for alkali and even for alkaline earth ions. It was possible to obtain cation locations for Cs+ as well as for Ba2+ ions in ZSM-5. In this context the series of far-infrared spectra of alkali exchanged ZSM-5 is shown for the first time.
