Probing the structure of metal cluster-adsorbate systems with high-resolution infrared spectroscopy.
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-Mg(n) (n = 1 to 4). The results suggest a qualitative change in the adsorbate-metal cluster bonding with cluster size.
