Transition Metal Cluster Chemistry.

Abstract

Reactions of transition metal cluster ions are examined using guided ion beam techniques. These techniques allow ionic clusters of variable size and composition to be isolated. Measurement of reaction cross sections and branching ratios characterize the interactions of the clusters with a variety of neutral gases. By examining the variation of these quantities with the kinetic energy of the cluster ions, extensive thermochemical data for both ionic and neutral cluster species can be determined. Prototypical data for Mn(2)+ and Co(2)+ have been obtained. In addition, a new source of cold metal cluster ions (both bare and ligated) has been developed and demonstrated. Keywords: Transition metals, Clusters, Ion chemistry.
