001028431 520__ $$aPhotoemission 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.
