Vibrational Broad-Band Sum-Frequency Generation Spectroscopy (BB-SFG) is the second-generation SFG method for studying surfaces, including wet electrochemical interfaces. Simultaneous electrochemical and BB-SFG measurements are presented for adsorption/oxidation of CO on well-ordered Pt(hkl) electrodes with both CO-free and CO-saturated electrolytes. The emphasis will be on the combination between thin layer electrochemistry and vibrational electrode surface analysis, and on dynamics of Pt/solution interfaces probed by the CO molecule adsorption and oxidation. This is an abstract of a paper presented at the 231st ACS National Meeting (Atlanta, GA 3/26-30/2006).
