Metal Cluster opportunities — •Gereon Niedner-Schatteburg — Fachbereich Chemie, RPTU Kaiserslautern-Landau

Isolated Main group Metal Clusters (MMC) and those of Transition Metals (TMC), both provide for unique physical properties and chemical activities which are neither found in single atoms nor in bulk metals. Variation of cluster sizes provide for a scalable tuning of these properties, with some cluster size and shape related non scalable exceptions superimposed. Empirical scaling laws often find a descriptive interpretation while the non scalable exceptions receive or await support by explicit quantum chemical modelling. It is a major prevailing challenge to record and to describe appropriately TMCs electronics and their spin couplings. Upon deposition onto strongly interacting surfaces the properties of MMCs and TMCs may change significantly, and much less by weakly interacting surfaces.

The presentation reviews and exemplifies some of these aspects in complement to the prior Symposium on the Spectroscopy of Metal Clusters (SYMC). It concludes with a short outline of likely applications and limitations.
