Spectroscopic line shapes of vibrational quanta in the presence of molecular resonances. - In: The journal of physical chemistry letters, ISSN 1948-7185, Bd. 7 (2016), 13, S. 2388-2393
Line shapes of molecular vibrational quanta in inelastic electron tunneling spectroscopy may indicate the strength of electron-vibration coupling, the hybridization of the molecule with its environment, and the degree of vibrational damping by electron-hole pair excitation. Bare as well as C60-terminated Pb tips of a scanning tunneling microscope and clean as well as C60-covered Pb(111) surfaces were used in lowtemperature experiments. Depending on the overlap of orbital and vibrational spectral ranges different spectroscopic line shapes of molecular vibrational quanta were observed. The energy range covered by the molecular resonance was altered by modifying the adsorption configuration of the molecule terminating the tip apex. Concomitantly, the line shapes of different vibrational modes were affected. The reported observations represent an experimental proof to theoretical predictions on the contribution from resonant processes to inelastic electron tunneling.

Superstructures and electronic properties of manganese-phthalocyanine molecules on Au(110) from submonolayer coverage to ultrathin molecular films. - In: Langmuir, ISSN 1520-5827, Bd. 32 (2016), 27, S. 6843-6850
The adsorption of manganese-phthalocyanine molecules on Au(110) was investigated using a low-temperature scanning tunneling microscope. A rich variety of commensurate superstructures was observed upon increasing the molecule coverage from submonolayers to ultrathin films. All structures were associated with reconstructions of the Au(110) substrate. Molecules adsorbed in the second molecular layer exhibited negative differential conductance occurring symmetrically around zero bias voltage. A double-barrier tunneling model rationalized this observation in terms of a peaked molecular resonance at the Fermi energy together with a voltage drop across the molecular film.

Energy and spectroscopic line shape of the C-O stretch mode on Ir(111) in the presence of organic molecules. - In: The journal of physical chemistry. Energy, materials, and catalysis / American Chemical Society. - Washington, DC : Soc., 2007- , ISSN: 1932-7455 , ZDB-ID: 2256522-X, ISSN 1932-7455, Bd. 120 (2016), 21, S. 11490-11497
Measuring molecular interactions on surfaces requires subtle probes. Electron energy loss spectroscopy was used to determine that the C-O stretch mode energy of CO on Ir(111) gradually decreased due to the increasing coverage of coadsorbed phthalocyanine molecules. Density functional calculations rationalized the energy shift in terms of static electric dipole interactions, which affect the C-O stretch mode energy via the vibrational Stark effect. Starting from the lowest phthalocyanine coverage up to the nearly closed monolayer the spectroscopic signature of the C-O stretch mode adopted a rather broad and asymmetric line shape. This observation was traced to different phthalocyanine-CO distances and thus different dipole fields at the CO site, which gave rise to a finite distribution of vibrational energies. Additional calculations demonstrated that the influence of dynamic dipole coupling, intermolecular charge transfer and adsorbate-induced substrate lattice relaxations on the C-O stretch mode energy was negligible. The findings may be relevant to scanning probe methods striving for local force measurements.
