研究领域
The Fayer group is involved in research on the dynamics and interactions of molecules in complex molecular materials. Systems that have mesoscopic structure and other types of complex structures and dynamics are common in nature and have properties that are distinct from a typical bulk material. For example, water in a nanoscopic pool of several hundred water molecules behaves very differently from bulk water. To study such systems, we are applying a variety of ultrafast nonlinear experiments including two dimensional infrared vibrational echo spectroscopy, other ultrafast IR methods, and ultrafast visible and UV experiments. We are exploring dynamics and intermolecular interactions of molecules in liquids, liquids in nanoscopic environments, room temperature ionic liquids, polymers, polymer membranes, and perovskites.We are also studying solute-solvent dynamics and interactions such as complex formation and dissociation and isomerization. A prominent area of our research is the dynamics of water in nanoconfinement, interacting with interfaces, and with ions, as well as dynamics of biological membranes. Proton transfer in water and other liquids and in nanoscopic systems. We are also investigating highly concentrated aqueous salt solutions. We develop methodologies and theory of ultrafast multidimensional vibrational spectroscopy and other ultrafast optical methods for general probes of structural dynamics in complex molecular systems. We also develop and apply statistical mechanics theory of molecular systems and experimental observables.
