Book Description
Two new types of infrared spectrometers have been developed for the study of gas-phase cluster species. A tunable far-infrared (FIR) laser was combined with an apparatus for producing planar supersonic beams of laser vaporized clusters, and used in the measurement of the 64.1 cm-1 bending vibration of c sub 3. A mid-IR diode laser system was constructed with a similar cluster source, and used in studies of the C sub 4, C sub 5, C sub 7, and C sub 9 clusters. Structures and internal dynamics of the clusters were determined. Extensions to metal cluster systems are currently underway. A new type of spectrometer was developed for measuring electronic spectra of supersonic metal clusters. Cavity Ringdown Laser Absorption Spectroscopy (CRLAS) was utilized in a study of the Cu sub 3 cluster in the initial application of the method.

Book Description
Due to the interaction with the contact medium, the properties of clusters may change or even disappear. Thus the physics of cluster-on-surface systems -- the main subject of this book -- is of fundamental importance. The book addresses a wide audience, from the newcomer to the expert. Starting from fundamental concepts of adsorbate-surface interactions, the modification of electronic properties through electron confinement, and concepts of cluster production, it elucidates the distinct properties of the new metallic nanostructures.

Book Description
The cluster which is an ensemble of two thousands of atoms or molecules, has emerged as a completely new class of materials at the frontier of materials science. The frontier of cluster science extends so rapidly that the map of the science is renewed day by day. In order to provide basic knowledge and recent information on this growing field, 14 world-renowned scientists who are actively involved experimentally and theoretically in cluster science have written this book, which is concise, comprehensive, suitable for students at both the undergraduate and the graduate level, as well as people who work outside cluster science. Contents: Survey of Structure, Energetics and Dynamics of Clusters (R S Berry & R D Levine); Molecular and Ionic Cluster Spectroscopy (J M Lisy); Physical and Chemical Properties of Metal Clusters in the Gas Phase and on Solid Surfaces (A Terasaki); Femtosecond Spectroscopy on Metal Clusters (a Vajda et al.); Core Level Excitation of Clusters (E Rhl); Laboratory Experiments on Single Levitated Aerosol Particles (T Leisner); Cluster Formation from Liquid Phase (F Mafun(r)). Readership: Researchers in atomic physics, molecular physics and physical chemistry."

Book Description
Gas phase clusters were produced composed of a metal ion bound to one or more molecular "ligands" (e.g., water, nitrogen, acetylene, methanol, etc.). These gas phase complexes were studied with mass-selected laser photodissociation spectroscopy and laser photoelectron spectroscopy (ZEKE) . These studies determine the structures and energetics of these clusters and they probe the dynamics of nascent solvation processes. Other metal clusters and metal-organic complexes were produced in the gas phase and evaluated for their potential for isolation in macroscopic quantities. Mass spectrometry and laser photodissociation measurements were employed for metal carbides, metal-C60 complexes and complexes of metal with polyaromatic hydrocarbons. These studies provide detailed experimental data which can be compared to theory to improve the overall understanding of metal-molecular interactions.

Book Description
This book discusses current techniques and instrumentation for cluster chemistry. It addresses both the experimental and theoretical aspects of gas-phase metal cluster reactivities, especially those pertaining to pollution removal, energetic reactions and corrosion and anticorrosion. These metal cluster systems have attracted enormous interest as they display a completely new class of physical, chemical, electronic, magnetic and catalytic properties. As these properties change with size and composition, it can thus be understood how their nature evolves from atoms to bulk solids. The book offers readers a basic understanding of the structural chemistry and reactivity of metal clusters in both gas-phase and wet chemistry. Further, the lessons they learn here regarding metal cluster chemistry will prepare researchers for the study of condensed phase dynamics that pertain to wet chemical synthesis, soft-landing deposition and cluster assembly.

Book Description
The field of nanoscience was pioneered in the 1980s with the groundbreaking research on clusters, which later led to the discovery of fullerenes. Handbook of Nanophysics: Clusters and Fullerenes focuses on the fundamental physics of these nanoscale materials and structures. Each peer-reviewed chapter contains a broad-based introduction and enhances
