| Abstract: | Basicity of silanol oxygen atom increases after adsorption of ammonia or pyridine, as revealed by FTIR spectra of adsorbed CHF3 and CO2. The same effect of “induced basicity” was observed for the dangling hydroxyl groups of ice surface with coadsorbed ethylene and fluoroform. Possible role of the induced acidity and basicity in surface chemistry is discussed. |
