Volume 1: General Introduction to Molecular Sciences Volume 2: Physical Aspects of Molecular Systems Volume 3: Electronic Structure and Chemical Reactivity Volume 4: Molecular Phenomena in Biological Sciences

These proceedings review and report on recent research on biological luminescence, covering both the basic and applied aspects in different disciplines of science.

The subject of this book--intermolecular interactions-- is as important in physics as in chemistry and molecular biology. Intermolecular interactions are responsible for the existence of liquids and solids in nature. They determine the physical and chemical properties of gases, liquids, and crystals, the stability of chemical complexes and biological compounds.

In the first two chapters of this book, the detailed qualitative description of different types of intermolecular forces at large, intermediate and short-range distances is presented. For the first time in the literature, the temperature dependence of the dispersion forces is analyzed and it is shown that the famous Casimir-Polder formula for dispersion forces is incorrect at any finite temperature. The author has aimed to make the presentation understandable to a broad scope of readers without oversimplification. In Chapter 3, the methods of quantitative calculation of the intermolecular interactions are discussed and modern achievements are presented. This chapter should be helpful for scientists performing computer calculations of many-electron systems.

The last two chapters are devoted to the many-body effects and model potentials. More than 50 model potentials exploited for processing experimental data and computer simulation in different fields of physics, chemistry and molecular biology are represented. The widely used optimization methods: simulated annealing, diffusion equation method, basin-hopping algorithm, and genetic algorithm are described in detail.

Significant efforts have been made to present the book in a self-sufficient way for readers. All the necessary mathematical apparatus, including vector andtensor calculus and the elements of the group theory, as well as the main methods used for quantal calculation of many-electron systems are presented in the appendices.

All those working on the theoretical and experimental studies of intermolecular interactions in chemistry, physics, biochemistry and molecular biology will find this text of interest and it will appeal to advanced undergraduates, graduates and researchers.

This book describes the history and future views of high conductivity solid ionic conductors, ionic transport theories in solids, relations between structures and ionic transport in solid ionic and ionic electronic mixed conductors.

Current understanding of different phases as well as the phase transitions between them has only been achieved following recent theoretical advances on the effects of dimensionality in statistical physics. P S Pershan explains the connection between these two separate areas and gives some examples of problems where the understanding is still not complete. The most important example is the second order phase transition between the nematic and smectic-A phase. Others include the relation between the several hexatic phases that have been observed and the first order restacking transitions between phases that were all previously identified as smectic-B, but which should more properly be identified as crystalline-B. Some relatively recent experimental developments on the discotic phase, liquid crystal surfaces and lyotropic phases are also included. The book includes 41 major reprints of some of the recent seminal work on the structure of liquid crystals. They are introduced by a brief review of the symmetries and other properties of liquid crystalline phases. In addition, there is a discussion of the differences between true liquid crystalline phases and others that were described as liquid crystalline in the early literature, but which have since been shown to be true three-dimensional crystals. The progression from the isotropic fluid, through the nematic, smectic, and various crystalline phases can be understood in terms of a systematic decrease in symmetry, together with an accompanying variation in structure is explained. A guide to the selected reprints and a sort of "Rosetta Stone" for these various phases is provided. The goal of this book is to explain the systematics of this progression to students and others that are new to this field, as well as to provide a useful handbook for people already working in the field.

It is now more than 20 years since the book "Radical Ions" edited by Kaiser and Kevan appeared. It contained aspects regarding generation, identification, spin density determination and reactivity of charged molecules with an odd number of electrons. New classes of reactive ion radicals have been detected and characterised since then, most notably cation radicals of saturated organic compounds. Trapping of electrons has been found to occur not only in frozen glasses but also in organic crystals. The structure and reactions of anion radicals of saturated compounds have been clarified during the last 20 years. We have asked leading experts in the field to write separate chapters about cation radicals, anion radicals and trapped electrons as well as more complex systems of biological or technological interest. More attention is paid to recent studies of the ions of saturated compounds than to the older and previously reviewed work on aromatic ions. In the case of trapped electrons full coverage is out of the question, and focus is on recent efforts to characterise the solvation structure in ordered and disordered systems.

The papers included in this volume were presented at the symposium on "Americium and Curium Chemistry and Technology" at the International Chemical Congress of Pacific Basin Societies in Honolulu, Hawaii, December 16-21, 1984. This symposium commemorated forty years of research on americium and curium. Accordingly, the papers included in this volume begin with historical perspectives on the discovery of americium and curium and the early characterization of their chemical properties, and then cover a wide range of subjects, such as thermodynamic properties, electronic structure, nuclear reactions, analytic chemistry, high pressure phase transitions, and technological aspects. Thus, this volume is a review of the chemistry of americium and curium, and provides a perspective on the current research on these elements forty years after their discovery. The editors would like to thank the participants in this symposium for their contributions. It is a pleasure to acknowledge the assistance of Ms. Barbara Moriguchi in handling the administrative aspects of the symposium and of the production of this volume. April 2, 1985 Norman M.

Volume 2 of this two-volume set offers food scientists and food chemists unique coverage of techniques/applications and methodologies widely used to study biopolymers in general, and food biopolymers in particular. A synthesis of information previously found only in numerous texts and research articles, this volume offers detailed, coverage of both scattering (light, x-ray, neutron) and spectroscopic techniques (NMR, ESR, FT-IR vibrations), circular dichoism, along with numerous applications. Genetic engineering and novel biothechnology methods are presented together with quantitative composition analyses of foods by supercritical fluid chromatography (SFC). This book should be of interest to food scientists and food chemists.

The idea of this NATO school was born during philosophical discussions with Dr Brevard on the present and future of NMR during a night walk under the palm trees in Biskra during a seminar held in this oasis. It was clear for us that the recent progress in the field of NMR, especially inverse spectroscopy and the development of MAS, was opening new perspectives for chemists. We realised also that organometallic and inorganic chemists were not clearly informed about the potentialities of all the new methods. NA TO, with its summer schools, was offering a good opportunity to propose to the chemical community a session where those problems would be largely developped. This School is then the prolongation of the two previous ones: Palermo in 1976 on "the less receptive nuclei" and Stirling in 1982 on "the multinuclear approach to NMR spectroscopy" . It was divided into two sub-sessions: NMR in the liquid state and NMR in the solid state. This is reflected in the book organization. As indicated by the title of this School, we were mainly concerned with the methodological aspects of multinuclear NMR. If many examples are given, they appear only as a support for the understanding of the theory or in explanation of some practical aspects of the different experiments. Each domain is introduced by a lecture which presents selected examples.

This volume contains the lectures presented at the Advanced Study Institute on "New Trends in Coal Science" which was held at Datca, HUgla, Turkey during August 23 - September 4, 1987. The book includes 23 chapters which were originally written for the meeting by some of the world's foremost investigators. Chemists everywhere are carrying out exciting research that has important implications for the energy and fuels industries and for society in general. For the near future, coal resources will continue to be of great importance and science and technology of the highest order are needed to extend this fossil energy resource and to utilize it in an economical way that is also environmentally acceptable. These were the main purposes for the organization of this NATO ASI. The Institute constituted two working weeks on structure and reactivity of coal and so is the book. Through the presentation of many specific recent results on structure and characterization of coal and its products the potential of new instrumental techniques is presented in the first part of the book. Finally the reactivity of coals at different conditions both in laboratory and industry is discussed. We hope that the volume will be of great use to research workers from academic and industrial background. In addition it could serve as a textbook for a graduate course on coal science and technology.

This volume of 18 papers describes the glacial-marine sedimentary environment in a variety of temporal and spatial settings. The volume's primary emphasis is the characteri zation of Quaternary glacial-marine sedimentation to show (1) the significant differences that exist between glacial marine environments in different geographic settings and (2) their resulting glacial-marine deposits and facies. Addi tionally, papers describing ancient glacial-marine environ ments are also presented to illustrate lithified analogs of the Quaternary deposits. With the Doctrine of Uniformitarianism in mind (the present is the key to the past), it is hoped that this volume will serve to expand the horizons of geologists working on the rock record, especially those whose primary criteria for recognition of ancient glacial-marine environments is the presence of dropstones in a finer-grained matrix. As the papers presented here show, diamictite is only one of many types of deposits that form in the glacial-marine sedimentary environment. Papers presented in this volume examine the Quaternary glacia1-marine sedimentary picture in subarctic Alaska, Antarctica, the Arctic Ocean, the Kane Basin, Baffin Island, the Puget-Fraser Lowland of Washington and British Columbia, and the North Atlantic Ocean. Ancient glacia1-marine depos its described are the Neogene Yakataga Formation of southern Alaska, the Late Paleozoic Dwyka Formation of the Karoo Basin of South Africa, and the Precambrian Mineral Fork Formation of Utah. For continuity, a paper summar1z1ng the temporal and spatial occurrences of glacial-marine deposits is also presented."

This is the first volume of a comprehensive two-volume set on the physical chemistry of food processes.

The past few decades have witnessed remarkable growth and progress in our knowledge  concerning the structure and properties of aperiodic systems at a microscopic level. The present volume provides a timely overview of the current state of the art on the structure, electronic and magnetic properties of aperiodic materials, including structural inhomogeniety. It also describes the theoretical calculation methodology. The subject is approached both from the basic science and the applied engineering points of view. Many references, illustrations and tables assist specialists and non-specialists alike to gain access to the growing body of essential information.

Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued. The current list of Specialist Periodical Reports can be seen on the inside flap of this volume.

Potash is the term generally given to potassium chloride, but it is also loosely applied to the various potassium compounds used in agriculture: po tassium sulfate, potassium nitrate or double salts of potassium and magne sium sulfate (generally langbeinite, K S0 * 2MgS0 ). Sometimes the var 2 4 4 ious compounds are differentiated by the terms muriate of potash, sulfate of potash, etc. When referring to ores, or in geology, all of the naturally found potassium salts are called "potash ores". However, originally potash referred only to crude potassium carbonate, since its sole source was the leaching of wood ashes in large pots. This "pot ash" product was generally recovered from near-seacoast plants, such as the saltwort bush, whose ashes were richer in potassium than sodium carbonate. Inland plant's ashes were generally higher in sodium carbonate, giving rise to the word alkali from the Arabic word for soda ash, al kali. The term was then carried over after potassium was discovered to form the latin word for it, kalium. The recovery of potash from ashes became a thriving small cottage industry throughout the world's coastal areas, and developing economies, such as the early set tlers in the United States were able to generate some much-needed income from its recovery and sale. This industry rapidly phased out with the advent of the LeBanc process for producing soda ash in 1792, and the discovery about the same time of the massive sodium-potassium nitrate deposits in the Atacama Desert of Chile.
