Analytical & physical chemistry, freeze-frame spectroscopy, catalytic reaction mechanisms

The primary goal of the Moore group research program is to gain a detailed understanding of catalytic reaction mechanisms involving various metallic and non-metallic nanoparticles (NPs). To achieve this, my lab is developing a new approach called “freeze-frame” spectroscopy, which involves the use of liquid helium nanodroplets to stabilize pre- and post-reactive complexes of free NPs with reactant molecules. These complexes are then probed using infrared spectroscopy, and structural assignment is achieved based on predictions from computational studies.
