What would you do if you had the fastest camera in the universe? I would use it to see how electrons move in molecules to transform our knowledge of chemical reactions – if it was fast enough. To really transform chemistry, we need to know how electrons move around a molecule at the earliest moments of a reaction. This motion creates the initial conditions that dictate the rest of the reaction. So how fast of a shutter speed does our camera need to capture this electron motion and see chemical bonds break and form in real time? This is the timescale of “atto-seconds,” the natural timescale of electronic motion. As a Packard Fellow, I will create the novel experimental capabilities necessary to discover, and establish, a fundamentally new era of “attochemistry” in condensed phase molecular and materials research.
