✦ Synopsis

I present a theory for how dipole-forbidden adsorbate vibrations can be excited in infrared reflection absorption spectroscopy from molecules adsorbed on metallic surfaces, and in the light of the theory I discuss the experimental data of Hirschmugl et al. for the CO/Cu( 100) chemisorption system. The frequency-dependent background absorption observed for this system is explained and a qualitative insight into the origin of the various observed effects is given.

We derive a simple relation between the change in dc resistivity &J of a thin metallic film due to adsorption of molecules on the film surface and the electron-hole pair damping (lifetime T) of the parallel frustrated translations of the adsorbates. From the measured 3p for several different adsorba
