      abstract     = {Time-resolved photoemission orbital tomography (tr-POT)
                      offers unique possibilities for tracing molecular electron
                      dynamics. The recorded pump-induced changes of the
                      angle-resolved photoemission intensities allow to
                      characterize unoccupied molecular states in momentum space
                      and to deduce the incoherent temporal evolution of their
                      population. Here, we show for the example of CuPc/Cu(001)-2O
                      that the method also gives access to the coherent regime and
                      that different excitation pathways can be disentangled by a
                      careful analysis of the time-dependent change of the
                      photoemission momentum pattern. In particular, we
                      demonstrate by varying photon energy and polarization of the
                      pump light, how the incoherent temporal evolution of the
                      LUMO distribution can be distinguished from coherent
                      contributions of the projected HOMO. Moreover, we report the
                      selective excitation of molecules with a specific
                      orientation at normal incidence by aligning the electric
                      field of the pump light along the molecular axis.},
