Infrared Spectroelectrochemical Measurements Of The Electrochemical Double Layer: Using Carbon Monoxide As A Double Layer Probe Molecule, Andrea Russell, Stanley Pons, Mark Anderson
Mark R. Anderson
The utility of infrared spectroelectrochemical measurements to provide information about the electrochemical interface has been previously demonstrated. The use of small adsorbate molecules as probes of the interface has only recently been investigated. The infrared spectroscopic behavior of adsorbed carbon monoxide in the presence of methanol, ethanol, n-propanol, isopropanol, and ethylene glycol as well as in alcohol/water binary solvent mixtures is presented. Changes in the Stark tuning rate for the adsorbed CO are correlated with solvent dipole reorganization in methanol, ethanol, and n-propanol. No change was observed for ethylene glycol or isopropanol. For the binary mixtures, a dramatic change in …
