Physical/Analytical Chemistry
The Physical Chemistry Division comprises highly collaborative research groups in laboratory measurement and theoretical and computational simulations that, in turn, work closely with the other divisions in the department to answer the most pressing questions in chemistry. Capabilities include state-of-the art ultrafast spectroscopic tools operating across the entire chemistry-relevant electromagnetic spectrum, molecular- and atom-scale in situ microscopes, probes for short-lived excited state species, a wide suite of bulk and surface tools applicable at all necessary length and time scales, and cutting-edge computational tools and methods for accurately describing nuclear motion and electronic structure.
