abstract = {Photoemission orbital tomography (POT) is an established
technique to investigate the electronic properties of
organic adsorbates on surfaces. In POT, a combined
experimental and theoretical approach, angle-resolved
photoelectron spectroscopy data are measured in a large
angular range at a constant kinetic energy and compared to
calculated wave functions of organic molecules. To simulate
the photoemission process, the final state of the
photoelectrons is approximated by a plane wave (PW). Then,
the experimentally-obtained photoemission intensity
distribution can be correlated directly to theoretical
density of states to identify individual orbitals. Due to
the used PW approximation (PWA), POT is commonly restricted
to π orbitals of large, planar molecules, and a particular
experimental geometry. Yet, some reports in literature
suggest that POT is not fixed to these conditions. In this
work, we verify the limits of POT and thus extend its
potential.},
