In the Kretschmann ATR configuration, a short-range strong electric field is generated on the surface of a thin metal film by the collective resonance of free electrons upon incidence of infrared light. This strong field enhances the intensity of infrared absorption from species present in the immediate neighborhood of the metal surface. In a few cases, infrared absorption of adsorbed species is enhanced through the coupling of vibration modes with charge-transfer excitation. Consequently, the Kretschmann ATR configuration is feasible for the in-situ observation of infrared spectra of species on metal surfaces without significant interference of signals from bulk species.
