Nonlinear Vibrational Spectroscopy Characterizing Model Atmospheric, Geological, Environmental, and Biological Surfaces and Interfaces

EMSL Project ID


We propose to use SFG-VS to study the vibrational spectroscopy at aqueous and non-aqueous solution surfaces, aqueous solution/oxides surfaces and interfaces of model molecular systems that is related to atmospheric, geological, environmental and biological surfaces and interfaces on their chemical interactions and processes. The EMSL surface spectroscopy and dynamics capability is to provide the platform for studying the specific scientific problems in this project, especially the newly developed sub-wavenumber high-resolution broadband sum-frequency generation vibrational spectrometer (HR-BB-SFG-VS). The uniqueness of this platform results from fully utilizing the recent instrumentation and methodology developments in surface nonlinear spectroscopy. Specific tools and experimental setups to study aqueous and non-aqueous solution surfaces, aqueous solution/oxide surfaces and heterogeneous catalytic solid surfaces are to be developed. To demonstrate the feasibility of these tools and capabilities for conducting effective SHG and SFG-VS on many of these surface problems is itself a significant advancement. We are planning to investigate benchmark systems in the interface sciences.
