Description
Photoemission orbital tomography has emerged as a powerful technique that relates measured photoemission angular distributions from oriented films of organic molecules with the molecular orbitals from which the electrons have been emitted. I will highlight its recent applications including the imaging of orbitals in three dimensions, the in-depth characterization of molecule/substrate hybridizations and the identification of surface reaction products. Finally, using femtosecond pump-probe spectroscopy, a new window into the dynamics of excited states has recently been opened. It brings us one step closer to the dream of directly watching in slow-motion videos how electrons move in quantum mechanical orbitals and how this motion shapes the functionalities of condensed matter.
