Abstract
A new approach for retrieving information on cation siting in silicon- rich zeolites like ZSM-5 is presented. It is based on combined investi gations using the cation sensitive methods, far-LR spectroscopy and EX AFS together with computer simulations. This combination proved to be successful for alkali and even for alkaline earth ions. It was possibl e 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 exchang ed ZSM-5 is shown for the first time.
