in surface studies, and benzalacetophenone has been used Infrared spectra are reported of silica preheated at 873 K and as a visual indicator of surface acidity (3). Benzophenones exposed at 295 K to the vapors of four acetophenones (H, 4are not sufficiently volatile for adsorption from the vapor Me

## Good agccmcnt of the results of numerical wlrulations with experimental data shows that rhc simple qrcscntarion of a Lewis acid site of an alumina surface as a positive point charge plus van der Waals interaction can dcscribc some chxactcristics of its interaction with ;I nitrogen moleculc.
Infrared spectra of acetophenone adsorbed on mordenite and acid-leached mordenite are reported. The effects of dealumination were characterized by pyridine adsorption and 29 Si and 27 Al magic angle spinning nuclear magnetic resonance spectroscopy (MAS NMR). Adsorption of pyridine gave bands at 1634
