About

Someone once said that physical chemistry is the study of anything that’s interesting. The members of the physical chemistry area use a wide variety of experimental techniques and theoretical studies to understand the fundamental structure and properties of matter. The problems we investigate range from vibrational dynamics in solids at very low temperatures to chemical dynamics in gases at high temperatures.

The development of short-pulsed lasers has allowed for direct probing of chemical reactions in real time. Typically, one laser pulse is used to initiate a chemical reaction, and a second pulse is used to probe the intermediates or products some time later. Chemical reactions in condensed phases are especially well suited to these techniques, since the steps in the reactions ...

Many phenomena occur primarily or exclusively at interfaces. These include adhesion, friction, lubrication, chromatographic separations, catalysis and many biological processes. The goal of our research is to establish links between molecular structure and function in interfacial systems. To accomplish this, we use a non-linear spectroscopy technique known as vibrationally resonant sum-frequency generation (VR-SFG). This technique allows us to probe molecules ...

We study the dynamics of chemical reactions. In particular, we are interested in studying events involving highly excited molecules with a chemically significant amount of energy. Highly excited molecules are of great importance, due to their reactivity; however, they are often extremely difficult to study as a result of their complexity. Reactants are produced using laser pumping techniques after which ...
