J. 5cherer Department of Chemistry University of California Berkeley, California Benoit 5oep Laboratoire de Photophysique Mol~culaire Universit~ de Paris-Sud Orsay, France PREFACE In Volume 3 of this series, we focus on the complex issues which arise in the determination of the structures of gas phase clusters. Although some cluster systems can now be isolated in bulk (e.g., the fullerenes), cluster science began in the gas phase and there are still more varied examples of clusters in this medium. Breckenridge, Jouvet, and Soep provide a comprehensive review of metal-rare gas complexes, where the details of metal-ligand interactions, electronic structure, and their implications for geometric structure are revealed in detail. Rohlfing looks at small polyatomic systems, where large-amplitude motions are important, making the concept of structure more difficult to define. Arnold and Neumark as well as Scherer, Paul, O'Keefe, and Saykally describe the application of nontraditional spectroscopy techniques and their a
