Attosecond time-resolved molecular electron dynamics — •Marc Vrakking — Max-Born-Institut, Berlin

Using attosecond light sources based on high-harmonic generation (HHG), pump-probe experiments can be performed where electron dynamics is studied on its natural timescale, providing insight into the fundamental role that electrons play in photo-induced processes.

In my talk I will present some of the first applications of these techniques in molecular science, focusing on two-color experiments where several small molecules were exposed to a sequence of one or more attosecond pulses and an infrared field. In addition to the attosecond time-structure accompanying HHG, the short wavelengths in HHG allow to use ejected photoelectrons as a probe of the (time-evolving) molecular structure, which amounts to *illuminating the molecule from within*. I will present the present status of our experiments on this topic.
