Abstract
The adsorption of benzene on Na beta and Cs beta followed by IR spectroscopy shows two pairs of CH out-of-plane bands. They are assigned to benzene interacting with either the cations, acidic sites or the oxygen of the 12-R window, basic sites. Ethylbenzene interacts only with the cations. In addition species similar to liquid benzene are detected below saturation of the adsorption sites. The basicity of the oxygen is higher than that predicted from the Al content. This may result from a specific structure influence.Keywords
