Our group's research focuses on using the inelastic laser light scattering technique known as resonance Raman spectroscopy to study the specific atomic-level motions that occur in a molecule or nanocrystal immediately after it absorbs light. This information is relevant to the photochemical and photophysical mechanisms important in optical sensing, optoelectronic devices, artificial lighting, solar energy conversion, and other technologies. Our work involves close coupling between experimental measurements and computational simulations of the Raman spectra. In addition to work on standard resonance Raman scattering, we have developed the two-photon analog, resonance hyper-Raman spectroscopy, as a tool to explore the structures and dynamics of two-photon allowed states of molecules and materials. A currently active and exciting area of research is the use of resonance Raman spectroscopy to probe how the vibrations (phonons) of semiconductor nanocrystals couple to the electronic states of these materials. |
