Imaging ultrafast chemical dynamics in the molecular frame

We develop methods to fix molecules in space, i.e., to align and orient them in laboratory space. The molecules are directly amenable to imaging their structures and dynamics in the molecular frame, which we approach using ultrashort electron and x-ray pulses for "coherent" diffractive imaging studies. In an alternative approach, we perform photoionization imaging experiments where the outgoing electrons have similar information encoded due to holographic interferences of the outgoing electrons or due to coherent rescattering of electrons on their counter ion.
