Welcome to the Nathanson Group

We use molecular beam scattering experiments to investigate the ways in which gas molecules are captured by and react with industrially important liquids and atmospheric aerosols. These experiments enable us to explore the interfacial analogues of bulk solvation, hydrogen bonding, the "like dissolves like" rule, proton exchange, electron solvation, and acid-base reactions. Scattering experiments can disentangle the elementary steps in interfacial and bulk reactions involving a wide range of gases and liquids (including pure and salty water, glycerol, sulfuric acid, molten carbonates, surfactant-coated liquids, and even sea spray). These pathways are illustrated in the figure for collisions of Cl2 with surfactant-coated glycerol. This system is used to model near-interfacial halogen exchange reactions that may lead to Br2-catalyzed destruction of ozone by sea-spray aerosol particles.
