Abstract
The intense electric fields present near the electrode-solution interface are sufficient to induce infrared activity of vibrational modes that are normally infrared inactive. The pure Stark effect, intensity enhancement by external electric fields, and charge-transfer effects are three mechanisms by which vibrational transitions in molecules at or near metal surfaces may be observed in addition to conventional absorption. Calculation of the expected absorption coefficients for adsorbed species gives values which are similar to those observed in surface electrochemical reflectance infrared techniques.
