The liquid phase oxidation of isopropanol catalyzed by platinum was studied with sum-frequency generation vibrational spectroscopy (SFG) in conjunction with reaction rate measurements.  The SFG spectra are presented as a function of solvent, bulk alcohol concentration, and ion concentration.  We correlate this spectroscopic data with the reaction rate and selectivity in order to identify intermediates in the oxidation pathway as well as other surface species which may be spectator species or intermediates in side reactions.  These studies elucidate the role of experimental conditions unique to the liquid phase catalytic oxidation in determining the activity and selectivity of heterogeneous catalysis on platinum.
