Ammonia adsorbed on Cu(110): An angle resolved x-ray spectroscopic and ab initio study
We present a study of a monolayer of ammonia (NH3) adsorbed on Cu(110) using core level spectroscopies in combination with ab initio calculations based on density functional theory. In particular,…
Manipulating the reactivity of nanoscale catalysts
This thesis presents the results of three di erent projects, all with focus on heterogeneous catalysis. The rst part concerns the investigation of the structure sensitivity of the CO dissociation…
THE ROTATIONAL STATE DISTRIBUTIONS OF PHOTODESORBED AMMONIA AS A LOCAL PROBE OF CORRUGATION
Photodesorption of ammonia follows a curved reaction path. Electronic excitation of, or electron attachment to, the adsorbate molecule leads to a transition from the pyramidal ground state to an…

TLDR
The origin of the differential ionization potential shifts of the CO 5 and NH 3 lone pairs observed in the photoemission spectra of these molecules chemisorbed on transition-metal surfaces is identified and these differential shifts do not indicate the nature of the adsorbate-metal chemical bond; they may, however, indicate the adsorption geometry.
