Research Interests

Our research interests are to investigate the structure-reactivity and characterization of small molecules, bimolecular complexes, transient chemical species, drug molecules, and nanoparticles using novel spectroscopic techniques at room (298 K) and low (0.38 to 10 K) temperatures and non-spectroscopic techniques (such as HPLC and MASS) to develop the fundamental understanding that applies to broad multidisciplinary fields of organic reactions, drug degradation and dissolution, green synthesis of nanoparticles, and atmospheric chemistry, etc. Within this general framework, our research program will address specific issues like the identification of transient species (ions and free radicals) and phytochemicals, the assignment of conformers generated during light and/or temperature-induced chemical transformations, and the formation of molecular complexes (via hydrogen, halogen, and carbon bonding). To achieve these, we integrate our expertise in spectroscopy, photochemistry, pyrolysis, dissolution, laser (CW & ns), HPLC, Mass, and low-temperature studies to probe reaction mechanisms. We employ quantum chemical (DFT & MP2) methods to model spectroscopic data and potential energy surfaces on which reactions occur.
