This volume, edited by a well-known specialist in the field of theoretical chemistry, gathers together a selection of papers on theoretical chemistry within the themes of mathematical, computational, and quantum chemistry. The authors present a rich assembly of some of the most important current research in the field of quantum chemistry in modern times. In Quantum Chemistry at the Dawn of the 21st Century, the editors aim to replicate the tradition of the fruitful Girona Workshops and Seminars, held at the University of Girona, Italy, annually for many years, which offered important scientific gatherings focusing on quantum chemistry. This volume, like the workshops, showcases a large variety of quantum chemical contributions from different points of view from some of the leading scientists in the field today. This unique volume does not pretend to provide a complete overview of quantum chemistry, but it does provide a broad set of contributions by some of the leading scientists on the field, under the expert editorship of two leaders in the field.

"This publication brings together contributions by eminent specialists in the field of the theoretical determination of electric polarizability. The contents of this book cover a wide area of subjects relevant to Chemical Physics, Molecular Physics, Nonlinear Optics and Materials Science. Specific subjects Ab initio and Density functional theory calculations of electric polarizability and hyperpolarizability, intermolecular forces, aromaticity, molecular design, electric properties of solvated molecules, NLO materials, Raman intensisties, polarizability of metal and semiconductor clusters, relativistic effects on electric properties, and more. Common experience had taught us that computational methods originally developed in a given basic science, e.g. physics, can be of paramount importance to other neighbouring sciences, e.g. chemistry, as well as to engineering or technology and, in turn, to society as a whole."

The principal focus of this volume is to illustrate the level of accuracy currently achievable by ab initio quantum chemical calculations. While new developments in theory are discussed to some extent, the major emphasis is on a comparison of calculated properties with experiment. This focus is similar to the one taken in a book, Comparison of Ab Initio Quantum Chemistry with Experiment for Small Molecules, edited by Rodney Bartlett (Reidel, 1984). However, the phenomenal improvement in both theoretical methods and computer architecture have made it possible to obtain accurate results for rather large molecular systems. This is perhaps best illustrated in this volume by the chapter entitled `Spectroscopy of Large Organic Molecules' by Bjorn Roos and coworkers. For example, the electronic spectra of the nucleic acid base monomer structures shown on the front cover have been obtained using a fully correlated ab initio study. For researchers, teachers and students in chemistry and physics.

The physics of clusters is a new and rapidly developing area. It is a frontier in the field of atomic and molecular physics, and condensed matter physics. One of the biggest concerns in the study of the physics of clusters is the methods of cluster measurements. The findings reported in this book on the methods of cluster measurements will lead to new avenues using nondestructive mass spectrometry and dipole mass isomers. Much attention is given to the physics and chemistry of fullerenes and nanotubes, including the problems surrounding the formation and growth of nanotubes, electron characteristics of fullerenes, the influence of solvents, simulation of the properties of carbon clusters, etc. Some unique experimental data on the conversion of aerosols into aerogels with the formation of fractal structures is provided. In addition, the book covers one of the most interesting subjects of modern physics — fractal clusters. Quantitative information on the thermodynamic properties of transition metal clusters, their binding energies to various ligands, and their reactions is obtained using a metal cluster guided ion beam mass spectrometer. Measurement of the thermodynamic stability of transition metal clusters is reported. The thermodynamic data given is unique, in that no comparable information has been obtained from any other method. Other topics of interest include atomic collision processes (including studies of electron attachment); oxidation; fundamental physical and chemical properties of clusters in the gas phase and in plasma (such as their geometrical and electron structure, magnetic, optical, chemical characteristics, etc.), and the wide range of their potential applications (including nucleation and growth of small particles such as aerosols, development of new materials with predetermined properties (cluster ensembles and nanophase materials), growing of thin films, cluster nanowire contacts, cluster lamps, dusty plasma, etc. Contents:Dusty Plasma and Hot Clusters:Ordered Structures in Low Temperature Dusty Plasmas (V E Fortov et al.)Cluster Plasma of Light Source (B M Smirnov)Clusters Consisting of Polar Molecules:Approaching Water Through Clusters (M D Tissandier et al.)Influence of Solvation Upon Electron Affinities of Polar Molecules (V Periquet et al.)Metal Clusters:Thermochemistry and Reactivity of Transition Metal Cluster Ions (P B Armentrout et al.)Shell Structure and Ionization Potentials of Lithium Monoxide Clusters (H Weidele et al.)Theory and Modeling of Clusters:Fullerenes in Solutions (A V Eletskii & M V Okun)Quantum Chemical Simulation of Non-Regular Covalent Structures (A S Kaklyugin & G E Norman)and other papers Readership: Researchers in plasma physics, condensed matter physics, materials science and physical chemistry.

This volume contains the proceedings of the NATO Advanced Research Workshop on Band Structure Engineering in Semiconductor Microstructures held at Il Ciocco, Castelvecchio Pascali in Tuscany between 10th and 15th April 1988. Research on semiconductor microstructures has expanded rapidly in recent years as a result of developments in the semiconductor growth and device fabrication technologies. The emergence of new semiconductor structures has facilitated a number of approaches to producing systems with certain features in their electronic structure which can lead to useful or interesting properties. The interest in band structure engineering has stimd ated a variety of physical investigations and nove 1 device concepts and the field now exhibits a fascinating interplay betwepn pure physics and device technology. Devices based on microstruc tures are useful vehicles for fundamental studies but also new device ideas require a thorough understanding of the basic physics. Around forty researchers gathered at I1 Ciocco in the Spring of 1988 to discuss band structure engineering in semiconductor microstructures.
