Charged Atmospheric Conglomerates: Role of Negative Ions in Heteromolecular Nucleation; The Properties of Small Clusters and Atmospheric Ions.
Abstract
There has been an enormous growth of interest in the properties of small particles and in the mechanisms by which they are formed. The research program undertaken in our laboratory was directed to a study of the fundamentals of nucleation about negative ions, with particular attention to an elucidation of the structure of small clusters, and the role of chemical bonding in establishing their stability. Using a new high pressure mass spectrometric technique, a systematic investigation of the bond energies and entropies of numerous ligand-negative ion complexes were determined. Concurrent theoretical work on the bonding of small complexes and ion-induced nucleation was also undertaken. The results have led to a more complete understanding of nucleation phenomena, and especially of the importance of cluster structure in the development of surfaces and in effecting phase transformations. In addition, the work has led to a clarification of some recent atmospheric observations reported in the literature.
