Population transfer in the multi-photon excitation of molecules — •Volker Engel, Marco Erdmann, and Stefanie Gräfe — Institut für Physikalische Chemie, Universität Würzburg, Am Hubland,*D-97074 Würzburg, Germany

The laser induced selective preparation of electronically excited molecular states is investigated, where the instantaneous dynamical response of the system to an applied field is employed to determine the latter. By construction, the obtained pulses carry the signature of the electronic and nuclear motion [1]. It is shown that an effective population transfer to different target states is possible. Time-dependent photoelectron spectra are calculated to illustrate that the achieved control yields can be measured directly [2].
