Kerpal, D. Harding, G. Meijer, A. Fielicke] The adsorption of carbon monoxide on neutral iridium clusters in the size range of n=3 to 21atoms is investigated with infrared multiple photon dissociation spectroscopy. For each cluster size only a single ν(CO) band is present with frequencies in the range between 1962 cm-1 (n=8) and 1985 cm-1 (n=18) which can be attributed to an atop binding geometry. This behaviour is compared to the CO binding geometries on clusters of other group 9 and 10 transition metals as well as to that on extended surfaces. The preference of Ir for atop binding is rationalised by relativistic effects on the electronic structure of the later 5d metals. EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg, 2010 Kerpal C.
