“…We can suppose that both the histogram shape and the rich presence of SEIRA enhancements indicate that, in fact, the surface also contains grains of sizes less than 1.5-2 nm, for which the surface selection rules are broken. [26] The SEIRA spectra show that we could register up to 1150 ng (383 ng cm…”

“…On the basis of the surface selection rule, the spectral feature can be ascribed to a specific orientation of a molecule, as mentioned above. However, Greenler et al [26] have performed both classical and quantum-mechanical calculations for the interaction of the electromagnetic field with the metal surface for particles of varying sizes, and arrived at the conclusion that surface selection rules should apply only for particles larger than about 1.5-2 nm.…”

Adsorption of guest molecules on host surfaces can lead to dramatic changes in the spectral properties of the guest. One such effect is surface-enhanced infrared absorption (SEIRA), observed when the guest is adsorbed on, for example, thin films, metal surfaces, or nanotubes. p-Nitrobenzoic acid (p-NBA) exhibits a SEIRA effect when adsorbed on Ag and Au. Herein, the IR spectra of p-NBA adsorbed on a homemade rough Au surface, recorded in reflection mode with an angle of incidence of 16.5°, are reported. This SEIRA experiment reveals more bands than found by previous SEIRA studies. The intensities of both symmetric and asymmetric COO(-) and NO(2) stretching, in-plane CH, and C=C ring stretching modes are enhanced. Theoretical models constructed on the basis of density functional theory reveal the binding mode of p-NBA to gold "particles". The p-NBA anion binds to gold much more strongly than the neutral form, and interaction via the carboxylic oxygen atoms is preferred over the nitro group-gold contact. A significant charge transfer during chemisorption is found, which is considered to be crucial in leading to a high SEIRA enhancement factor.

“…Infrared (IR) spectroscopy has been widely used for the characterization of molecular adsorbates on metals, both on monocrystalline substrates [14][15][16] as well as for metal particles [17,18]. Infrared reflection absorption spectroscopy (IRRAS) is a variant of IR-spectroscopy suited for the investigation of adsorbates on planar model surfaces.…”

Metal oxides are among the technologically most important materials. Almost all metals are covered by one oxide layer under ambient conditions. The characterization of oxide surface properties, therefore, is still attracting an increasing amount of attention in surface science. A challenge is provided by the fact that these materials cannot be studied with standard techniques in a straightforward fashion. In this review, we summarize recent results obtained by IRspectroscopy applied in a reflection-geometry to macroscopic oxide monocrystals. These results provide new insights in the adsorption and subsequent reactions and photoreactions of molecules on these highly interesting, very complex class of materials. In addition, the IR-spectroscopy can also be used to probe photophysical properties, e.g. the generation and decay of electron or hole polarons.
