The third WG will focus on the application of attosecond techniques to problems of chemical relevance, first by using the techniques that are already available and then by incorporating newly developed methods as they become available from the activities of the first two WGs.
The main objectives within this WG are as follows:
- investigation of the role of the early sub- and few-fs electron dynamics in the chemical changes that occur in a molecule on the much longer time-scale that leads to chemical changes
- investigation about how the interplay between electronic and nuclear dynamics determine the final localization of the charge on a specific molecular site or fragment
- investigation of how such dynamics is affected by the presence of the solvent
- analyzing the potential of high-harmonic spectroscopy in imaging charge dynamics in complex molecules
- exploring control strategies of chemical processes by directly acting on the attosecond time scale.
The WG3 will be structured in different research tasks involving the study of attosecond spectroscopy of charge migration induced by UV/XUV few-cycle pulses in target systems including donor-acceptor systems as well as biologically relevant and chiral molecules. Moreover, we aim to apply HHG spectroscopy on these molecules and to probe the attosecond imaging of coupled electron and nuclear dynamics at conical intersections. Finally, within the WG3, experiments with molecules embedded in water clusters and liquid water will be considered together with the possibility to implement control strategies based on attosecond-pulse shaping and pump-probe techniques.
