| | The structure of the electrochemical interface plays an important part in electrochemistry and electrocatalysis. We are interested in coupling surface sensitive in situ (IR and Raman) spectroscopic methods with conventional electrochemical techniques for the study of metal-solution interfaces. Results of the study are expected to follow changes in surface coverage down to a few percent of one monolayer. In our microwave spectroscopy laboratory, research is carried out to determine the conformations and structures of some organic and organometallic molecules. Information about chemical bonding, intramolecular hydrogen bonds, and/or dynamics of intramolecular motions are obtained. Infrared and laser Raman spectroscopic methods are also applied in these investigations. We are investigating supersonic free jet molecules coupled with low temperature spectroscopic techniques for the identification and characterization of intermolecular interactions. Other projects include surface enhanced Raman scattering (SERS) and surface enhanced resonance Raman spectroscopy (SERRS) methods for ultra-trace analyses of biomolecules and drugs. We also investigate solid surfaces which have been modified by different chemical methods including the silyl self-assembly monolayer (SAM) and the silyl sol-gel coating and the adsorption behavior of molecules at or near metal surfaces. |
