Archivio Istituzionale della RicercaWhen a molecule, engaged in H-bonding with an acidic proton in zeolites, is large enough to interact with the surrounding walls, the IR spectroscopic measure of the acidity is affected, but information may be gained on the geometry of the site. Examples concerning MCM-22, ZSM-5, SAPO-40, and Theta-1 are discussed.

Abstract
When a molecule, engaged in H-bonding with an acidic proton in zeolites, is large enough to interact with the surrounding walls, the IR spectroscopic measure of the acidity is affected, but information may be gained on the geometry of the site. Examples concerning MCM-22, ZSM-5, SAPO-40, and Theta-1 are discussed.
