Probing the Structure of Metal Cluster-Adsorbate Systems with High-Resolution Infrared Spectroscopy

K. Nauta, D. T. Moore, P. L. Stiles, R. E. Miller*

High-resolution infrared laser spectroscopy was used to obtain rotationally resolved infrared spectra of adsorbate-metal complexes. The method involves forming the bare metal clusters in helium nanodroplets and then adding a molecular adsorbate (HCN) and recording the infrared spectrum associated with the C-H stretching vibration. Rotationally resolved spectra were obtained for HCN-Mgn (n = 1 to 4). The results suggest a qualitative change in the adsorbate-metal cluster bonding with cluster size.
