Chemisorption of monocarboxylic acids on alumina: A tunneling spectroscopy study

Adsorption of stereoregular poly(methyl methacrylates) on ?-alumina: Spectroscopic analysis

“…For example, in (C-O 2Ϫ ) vibrating group, appears at 1590 cm Ϫ1 for the adsorbed PMMA 43 whereas it is not seen in the spectrum of the bulk sample. However, this band, which is relatively intense in the IR spectra of smooth surfaces (observed by specular reflectance), could not be used here for any quantitative analysis.…”

Characterization of the oxide/hydroxide surface of aluminium using x-ray photoelectron spectroscopy: a procedure for curve fitting the O 1s core level

“…The hydroxyl functionality at the surface of aluminium has been implicated in the formation of interfacial carboxylate functionalities with carboxylic acids 1,2 and is likely to play a role in the interaction with other organic functionalities. 3 The aim of this work is to develop a procedure enabling quantification, from XPS data, of the functional stoichiometry of the oxide/hydroxide film formed at the surface of aluminium.…”

Characterization of Metal Oxide Surfaces and Thin Semiconductor Films by Inelastic Electron Tunneling Spectroscopy

“…They concluded that although these aliphatic dicarboxylic acids are adsorbed as monocarboxylate anions on the surfaces, the νC=O peak of the COOH group in the tunneling spectra is attenuated by the presence of the Pb top electrode from a comparison of the MRAIR spectra. 63,64 The tunneling spectra of benzoic acid 5,17,18,[25][26][27][66][67][68][69][70]83 and various related compounds [16][17][18]26,41,51,56,65,[69][70][71][72][73][74][75][76][77][78]80,81,83 were measured and reported. Benzoic acid is adsorbed as benzoate anion on alumina and magnesia, giving a good tunneling spectrum with strong and well-resolved peaks.…”

“…16,17,26,56,[69][70][71][72][73][75][76][77][78]80,81 Monjushiro et al 76 measured the tunneling spectra of various o-substituted benzoic acids on alumina and studied the interaction of the substituted groups with the surface. They reported that the -COOH, -OH, and -SH groups interact strongly in this order, but the -NH2, -F,…”
