Time-resolved photoelectron spectra from coupled electronic-nuclear motion — •Mirjam Falge1, Volker Engel1, and Stefanie Graefe2 — 1Institut für Physikalische und Theoretische Chemie, Universität Würzburg, Am Hubland, 97074 Würzburg — 2Institute for Theoretical Physics, Vienna University of Technology, Wiedner Hauptstr. 8-10, A-1040 Vienna, Austria
We study the effect of electron-nuclei coupling on time-resolved photoelectron spectra resulting from femtosecond pump-probe ionization. Therefore, a model system is employed [1] which allows a straightforward switching from adiabatic to non-adiabatic dynamics. Non-adiabatic effects are identified in comparing Born-Oppenheimer calculations involving a discretization of the ionization continuum with a treatment where electronic and nuclear degrees of freedom are included explicitely.
