STM and XPS studies of the oxidation of aniline at Cu(110) surfaces

Article Abstract:

Aniline chemisorption at clean and partially oxidized Cu(110) surfaces at 293 K is compared with the reaction of a 300:1 aniline/dioxygen mixture at the same surface using STM and XPS. Limited dissociation occurs at the clean surface but in the presence of chemisorbed oxygen efficient oxy-dehydrogenation takes place with water desorption and the formation of chemisorbed phenyl imide [(C6H5N(a)] with a reaction stoichiometry that changes with coverage.

Watching ultrafast barrierless excited-state isomerization of pseudocyanine in real time

Article Abstract:

The photoinduced excited-state processes in 1,1'-diethyl-2,2'-cyanine iodine are investigated using femtosecond time-resolved pump-probe spectroscopy. The results show that the overall excited-state relaxation is separated into three distinct processes, hole replica broadening, directed excited-state torsional motion, and finally Brownian torsional motion in concert with radiationless transition back to the ground state.

The reactive chemisorption of alkyl iodides t Cu(110) and Ag(111) surfaces: A combined STM and XPS study

Article Abstract:

The chemisorption of methyl and phenyl iodide is studied at Cu(110) and Ag(111) surfaces at 290 K with STM and XPS. Dissociation of both molecules leads to chemisorbed iodine at both surfaces, but methyl groups are not stable and desorb immediately, presumably as ethane.
