Research was conducted to examine the chemistry of HNO3 on Ge(100). The initial bonding geometry and decomposition mechanism of HNO3 on Ge(100) is described. To gain an insight on the details of the complex, a combination of Auger elecrtron spectroscopy, high-resolution electron energy loss spectroscopy an temperature programmed desorption studies were employed. Results indicate that HNO3 adsorbs molecularly at 190 K in a bidentate bonding configuration.

Analyses performed on clean potassium-modified Pt(111) surfaces involved an examination of methylcyclohexane's (MCH) adsorption, desorption and reaction. The combined electronic effect of co-adsorbed alkali adatoms and the local postdosing effect of CHx from the methyl group significantly increases MCH to benzene conversion, especially benzene desorption. Preadsorbed carbon leaves the bonding energy unaltered and does not induce benzene desoption, though enhances the degree of revocable MCH adsorption.

High resolution electron energy loss spectroscopy (HREELS) was used to study ultrathin films of gamma- Al2O3 grown on NiAl (001). On the NiAl (001) surface, 1, 3- butadiene is pi- bonded to the surface until the substrate is heated to 300K, above which the butadiene converts to a sigma bonded structure.

The dimerization of 1,3-butadiene was performed to form 4-vinyl-cyclohexene on the surfaces of hydroxylated ultrathin films of gamma-Al2O3. The dimerization transpired via either a proton-induced cationic polymerization or by a Diels-Alder reaction activated by the interaction of butadiene molecules with the acidic surface of the OH groups. The dimerization reaction was absent when 1,3-butadiene was subjected to the non-hydroxylated surface of the gamma-AL2O3 film.
