Surface-enhanced Raman spectroscopic studies of the orientation of organonitriles on metal colloids
The orientation of adsorbates on metal colloids was studied by Surface enhanced Raman spectroscopy. We studied the orientation of cyanopyridines, aminomethylpyridines and 4-biphenylcarbonitrile on gold and copper colloids as a function of concentration of the adsorbates. It was found that the …

Interfacial Electronic Structure of Dipolar Vanadyl Naphthalocyanine Thin Films
… in both the ground and excited state manifolds. Systematic investigations of single systems using two-photon photoemission (TPPE) and ultraviolet photoelectron spectroscopy (UPS) were undertaken in order to assess the evolution of the electronic structure and molecular organization at the …

Selective excitation of adsorbate vibrations on dissipative surfaces
… regime ("vibrationally mediated chemistry"). For adsorbates on surfaces it has been theoretically predicted that IR preexcitation will lead to higher UV/Vis photodesorption yields and larger cross sections for other photoreactions. In a recent experiment, IR-mediated desorption of molecular …

Elektronen-Korrelationen und Elektron-Phonon-Kopplung in einem nanostrukturierten Adsorbatsystem
… in einem niedrigdimensionalen Adsorbatsystem untersucht. Ein solches System kann als einfaches Modellsystem zum Verständnis der Vielteilcheneffekte dienen. Mit Hilfe der Photoelektronenspektroskopie und Rastertunnelspektroskopie kann die Lebensdauer der Quasiteilchen direkt gemessen …
