We present new results on the vibrational spectra of molecules adsorbed or self-assembled on the metal and metal-oxide surfaces using the newly developed sub-wavenumber high resolution broadband sum-frequency generation vibrational spectroscopy (HR-BB-SFG-VS). HR-BB-SFG-VS provides unique capabilities to study the spectroscopic, structural and dynamic details of surface species as well as their interactions with the metal and metal-oxide surfaces through measurement and analysis of spectral splitting and lineshape. Specifically, alkyl thiols on gold surfaces and small organic molecules on silica surfaces are to be discussed.
