| Infrared absorption of molecules is enhanced remarkably when they are adsorbed on some metal surfaces consisting of nanoparticles (islands). The nano-sized morphology facilitates the interaction of IR photons with the metal and the adsorbed molecules, resulting in the enhanced absorption. The enhancing mechanism is discussed using a simple electromagnetic theory. Then the application of this effect to electrochemistry will be reported by focusing on adsorption of molecules (CO. Benzene, pyridine, etc.) on Cu electrodes. |
