The hopping of protons in the anionic framework of zeolite H-ZSM5 with different SiO 2 /Al 2 O 3 ratios was examined by complex impedance spectroscopy. We found that the activation energy for the hopping process depends on the spatial distance between the localization sites, given by the SiO 2 /Al 2
## Abstract Reported herein are the results of an investigation into the effect of the extended framework of the zeolite ZSMβ5 on the reaction energetics and structures of (a) the physisorbed complex formed between the zeolite and six alkenes, (b) the corresponding chemisorbed alkoxide intermediate
