The concepts of physical chemistry are central to all of molecular science: from the laws describing the properties and reactivities of molecules and clusters in the gas phase, to the principles that govern the structure and dynamics of molecular assemblies in the condensed phase and at interfaces; to the design of new materials and devices. Physical chemistry underpins all other branches of chemistry. For example, the theory and practice of NMR spectroscopy as it is known today had its origins in the fundamental research of many pioneering physical chemists and their research groups. Paul Lauterbur, a Ph.D. graduate of this Department and a world-renowned physical chemist, received the 2003 Nobel Prize in medicine for the development of magnetic resonance imaging.


Physical chemistry also plays an important role in many other fields, including environmental science, materials science, biology, and engineering. Members of our Physical Chemistry Group are involved in a range of collaborative, multidisciplinary research projects with researchers in other parts of the University including Physics, the Medical School and the School of Engineering, as well as at other Universities, National Laboratories, and Industry. Here, we briefly describe ongoing research activities in physical chemistry at the University of Pittsburgh.
