Dynamics of chirality explored via time-resolved photoelectron circular dichroism

Prof. Dr. Arno Ehresmann

We will investigate experimentally how the chirality of a molecule evolves during a dissociation process. For how long and under what conditions can the chirality be proven experimentally by time-resolved photoelectron circular dichroism? How may chirality be defined in dissociating systems with chiral or non-chiral fragments? To answer those questions, we will perform pump-probe experiments with split femtosecond X-ray pulses from free-electron lasers and with a combination of picosecond X-ray pulses from synchrotron radiation facilities and UV femtosecond laser pulses. In the dissociation processes we will follow the electrons and the nuclei in their respective time domains.
