Physical chemistry is concerned with the fundamental principles of chemistry, and serves as the underpinning for all other branches of chemical sciences. Anne Kelley's group focuses on using the inelastic laser-light scattering technique of resonance Raman spectroscopy to study atomic-level details of how molecules interact with light; the nonlinear optical properties of materials; and analytical applications of metal nanoparticles. David Kelley's group uses ultrafast optical spectroscopy to examine the optical and electronic properties of semiconductor nanoparticles that have potential in solar photovoltaics and display technologies. Christine Isborn's group uses time-dependent density functional theory to study photoexcitation and excitation energy transfer in complex systems. Tao Ye's group employs scanning probe microscopy to understand how molecules self-assemble at surfaces and interfaces. Matt Meyer's group uses kinetic isotope effects and computational chemistry to study chemical reaction dynamics. Erik Menke's group studies light absorption and exciton generation in semiconductor nanowires. Liang Shi's group employs theory and simulation to study heterogeneous molecular systems for energy applications.
