Ultrafast Electron Diffraction from Molecules in the Gas Phase

Ultrafast electron diffraction (UED) can provide information on the structure of molecules with sub-Angstrom spatial resolution and temporal resolution of approximately 1 ps. I will describe two recent applications of gas phase UED. In the first, we have used diffraction from laser-aligned molecules to retrieve the 3D structure of symmetric top molecules. In the second, we investigate the interaction of CS2 molecules with an intense laser field. We are interested in the regime where the laser intensity is high enough to induce alignment and deformation of molecules but still remains below the threshold for ionization. I will also briefly discuss ongoing improvements to the experimental setup to achieve 200 fs resolution and planned experiments on molecular dynamics.
