This book takes a fresh look at the wave function mathematics that provide the theoretical underpinnings of molecular spectroscopy. Original work demonstrating the advantages of algebraic theory over the conventional geometric approach to the subject is presented. This new approach has important implications for modern spectroscopy. Many examples are given to show comparisons of the two methods, and the relationship of the new method to current experiments.

Historically, science has strived to reduced complex problems to its simplest components, but more recently, it has recognized the merit of studying complex phenomena in situ. Fractal geometry is one such appealing approach, and this book discusses their application to complex problems in molecular biophysics. It provides a detailed, unified treatment of fractal aspects of protein and structure dynamics, fractal reaction kinetics in biochemical systems, sequence correlations in DNA and proteins, and descriptors of chaos in enzymatic systems. In an area that has been slow to acknowledge the use of fractals, this is an important addition to the literature, offering a glimpse of the wealth of possible applications. application to complex problems

Because of the importance of the hydrogen bond, there have been scores of insights gained about its fundamental nature by quantum chemical computations over the years. Such methods can probe subtle characteristics of the electronic structure and examine regions of the potential energy surface that are simply not accessible by experimental means. The maturation of the techniques, codes, and computer hardware have permitted calculations of unprecedented reliability and rivaling the accuracy of experimental data.This book strives first toward an appreciation of the power of quantum chemistry to analyse the deepest roots of the hydrogen bond phenomenon. It offers a systematic and understandable account of decades of such calculations, focusing on the most important findings. This book provides readers with the tools to understand the original literature, and to perhaps carry out some calculations of their very own on systems of interest.

This is a hands-on guide for the growing number of researchers in organic chemistry, biochemistry, and molecular biology who would like to augment their experiments with theoretical calculations. Given the current availability of sophisticated software, non-quantum chemistry practitioners can obtain accurate computational results and save significant amounts of laboratory time. This book teaches the use of quantum chemical computer programs while side-stepping the complex mathematical details. The book focuses on what kinds of biological problems can be solved by quantum mechanical calculations and how to select the appropriate methods.

High-temperature materials is a fast-moving research area with numerous practical applications. Materials that can withstand extremely high temperatures and extreme environments are generating considerable attention worldwide; however, designing materials that have low densities, elevated melting temperatures, oxidation resistance, creep resistance, and intrinsic toughness encompass some of the most challenging problems in materials science. The current search for high-temperature materials is largely based on traditional, trial-and-error experimental methods which are costly and time-consuming. An effective way to accelerate research in this field is to use recent advances in materials simulations and high performance computing and communications (HPCC) to guide experiments. This synergy between experiment and advanced materials modeling will significantly enhance the synthesis of novel high-temperature materials. This volume collects recent work from experimental and computational scientists on high-temperature materials and emphasizes the potential for collaboration. It features state-of-the-art materials modeling and recent experimental developments in high-temperature materials. Topics include fundamental phenomena and properties; measurements and modeling of interfacial phenomena, stresses, growth of defects, strain, and fracture; and electronic structure and molecular dynamics.

Application of compressed gases as solvents has found widespread interest within the scientific community. Its processes have industrial applications. Gas Extraction deals with the possibilities of supercritical gases as solvents for separation processes. The volume combines physico-chemical aspects with chemical engineering methods. The text generalizes as far as possible, and treats examples in detail. Gas Extraction covers, for the first time, the subject in textbook form. Most of the examples provide new results that will be helpful for practicing scientists, engineers, and students who want to make use of the techniques.

Most of the matter in our solar system, and, probably, within the whole universe, exists in the form of ionized particles. On the other hand, in our natural environ ment, gaseous matter generally consists of neutral atoms and molecules. Only under certain conditions, such as within the path oflightning or in several technical devices (e. g. gas discharges, rocket engines, etc. ) will some of the atoms and molecules be ionized. It is also believed that the chemistry of the earth's troposphere predomi nantly proceeds via reactions between neutral particles. (The complex system of atmospheric chemistry will be treated in one of the forthcoming volumes to this series. ) Why, then, are ions considered so important that hundreds oflaboratories all over the world (including some of the most prestigious) are involved in research pro grams on ions, covering many different facets, from biochemistry to physics? One may obtain as many different answers as there are research groups busy in this field. There is, however, one simple, common feature which makes it attractive to work with ions: since they carry one or more net elementary charges, they can easily be gui ded, focused or separated by appropriate electric and magnetic fields, and, last but not least, they can easily be detected. Apart from these advantages, which are welcome and appreciated by the researcher, the study of molecular ions can provide insight into very fundamental aspects of the general behavior of molecules.

In 1959, about 1400 compounds forming liquid crystalline phases were known; by 1992, this number had increased to about 50 000. In portable devices like wristwatches, pocket caculators, measuring instruments, and laptop computers the liquid crystal display technology has gained total acceptance and is on the way to encompass the market of colour TV screens. This development makes a volume devoted to liquid crystals in the series Topics in Physical Chemistry desirable. Following the concept of this series, an easy introduction to liquid crystals is given, enabling the reader to understand the basic problems of liquid crystals research and application. Because of the widespread field of different research activities in liquid crystals and applications, various competent authors have been involved in writing chapters on: - Phase types, structures, and chemistry of liquid crystals; - Thermodynamical behavior and physical properties of thermotropic liquid crystals; - Liquid crystalline polymers; - Lyotropic liquid crystals; - Application of liquid crystals in spectroscopy; - Application of liquid crystals in display technology.

The remaining years of our ending millennium are characterized by a tempestuous devel- opment of Surface Science, whose ultimate consequences are presently hard to foresee. While some of these consequenees are apparent to everybody (e. g. modern information eleetronies would hardly be possible without the progress in device fabrication whieh, in turn, has required profound knowledge of surface teehnology ) there are several other dis- ciplines where the impact of surface physical chemistry may not be so obvious, but, nevertheless, has contributed much to the technological progress made in the past, and is expected to cause even more such benefit in the future. We only list here the c1assical syn- thetic inorganic chemistry or the technical chemistry which have both greatly benefited from a more fundamental understanding of heterogeneously catalyzed (surface) pro- cesses leading to, among others, improved industrial fabrication processes.(We selec- tively mention the promising attempts to model the Fischer-Tropseh reaction or the ammonia synthesis reaction, remembering also the optimization of the hydrocarbon reforming proeess by developing appropriate bi metallic catalyst materials). Furthermore, materials science with its considerations of eorrosion, embrittlement, and fracture, as weIl as energy technology with its considerations of photovoltaics, hydrogen storage, or fuel cell development, must also be mentioned here. Many other important aspeets remain unmentioned, because of space limitations.
