Enhanced infrared absorption of adsorbates on smooth metal ultrathin films — •Andreas Priebe, Matthias Lust, Gerhard Fahsold, and Annemarie Pucci — Kirchhoff-Institut für Physik, Universität Heidelberg, Albert-Ueberle-Strasse 3-5, D69120 Heidelberg.

In normal transmission we observed strong infrared absorption lines for the stretching mode of CO on ultrathin Fe(100) prepared as smooth films, where field enhancement does not work. The signal strength and the lineshape were investigated with respect to iron film thickness.
