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 90 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.

NMR is better suited than any other experimental technique for the characterization of supramolecular systems in solution. The presentations included here can be broadly divided into three classes. The first class illustrates the state of the art in the design of supramolecular systems and includes examples of different classes of supramolecular complexes: catenanes, rotaxanes, hydrogen-bonded rosettes, tubes, capsules, dendrimers, and metal-containing hosts. The second class comprises contributions to NMR methods that can be applied to address the main structural problems that arise in supramolecular chemistry. The third class includes biological supramolecular systems studied by state-of-the-art NMR techniques.

The importance of molecular recognition in chemistry and biology is reflected in a recent upsurge in relevant research, promoted in particular by high-profile initiatives in this area in Europe, the USA and Japan. Although molecular recognition is necessarily microscopic in origin, its consequences are de facto macroscopic. Accordingly, a text that starts with intermolecular interactions between simple molecules and builds to a discussion of molecular recognition involving larger scale systems is timely. This book was planned with such a development in mind. The book begins with an elementary but rigorous account of the various types of forces between molecules. Chapter 2 is concerned with the hydrogen bond between pairs of simple molecules in the gas phase, with particular reference to the preferred relative orientation of the pair and the ease with which this can be distorted. This microscopic view continues in chapter 3 wherein the nature of interactions between solute molecules and solvents or between two or more solutes is examined from the experimental standpoint, with various types of spectroscopy providing the probe of the nature of the interactions. Molecular recognition is central to the catalysis of chemical reactions, especially when bonds are to be broken and formed under the severe con straint that a specific configuration is to result, as in the production of enan tiotopically pure compounds. This important topic is considered in chapter 4.

This successful textbook undergoes a change of character in the third edition. Where earlier editions covered organic polymer chemistry, the third edition covers both physical and organic chemistry. Thus kinetics and thermodynamics of polymerization reactions are discussed.

This edition is also distinct from all other polymer textbooks because of its coverage of such currently hot topics as photonic polymers, electricity conducting polymers, polymeric materials for immobilization of reagents and drug release, organic solar cells, organic light emitting diodes.

This textbook contains review questions at the end of every chapter, references for further reading, and numerous examples of commercially important processes."

The first review describes examples of very promising compounds discovered from plants acquired from Africa, Southeast Asia, the Americas, and the Caribbean region with potential anticancer activity. These include plant secondary metabolites of the diphyllin lignan, penta[b]benzofuran, triterpenoid, and tropane alkaloid types. The second review presents 40 more erythrinan alkaloids, which were either new or were missed out in the last major reviews, bringing to a total of 154 known erythrinan alkaloids known to date. The reported pharmacological activities of the new and known alkaloids showed a greater bias towards central nervous system and related activities. Other prominent activities reported were antifeedant or insecticidal, cytotoxicity/anti tumor/anti cancer/estrogenic, antiprotozoal, antiinflammatory, antioxidant, antifungal and antiviral activities.

The unique properties and applications of transition metal compounds have long fascinated both physicists and chemists. This volume presents theoretical and experimental studies for a deeper understanding of the electronic and vibronic properties of these compounds. In particular, an introduction into properties of spin sublevels of dd*, dA*, and AA* states is given, and a modern ligand field theory based on the Angular Overlap Model is presented. In experimental case studies it is shown how to characterize different types of electronic transitions using modern methods of laser spectroscopy. Consequences of spin-orbit coupling, zero-field splittings, spin-lattice relaxations, chromophore-matrix interactions, Herzberg-Teller/Franck-Condon activities, and localization/delocalization properties are treated.

This book contains a number of articles inspired by the NATO Advanced Study Institute on 'Charged and Reactive Polymers l' held in France in June 1972. This general title indicates simply the intention of a series. The meeting dealt mainly with the fundamental problems of the physical chemistry of polyelectrolytes in solution. Some of the articles reproduce the lectures exactly as they were delivered. Some others have been modified to a greater or lesser extent, and this as a result of improvements or new inspiration arising from comments and discussions. In previous larger conferences on macromolecules, polyelectrolytes constituted only a marginal problem and few were the individual communications or short was the time al10tted to this subject. In other meetings of a biophysical character the uses of the techniques of charged macromolecules have been exposed with less attention given to the theories or to the creation or interpretation of these techniques. AU of us felt that the time had come to enumerate and to evaluate this increasing science of polyelectrolytes which has become of major interest. During the whole period of the Institute physical chemists discussed their mutual problems for more than a week, and of ten far into the night One of the advantages of such an Institute is to enable the Directors and the mem bers of the Scientific Committee to establish a logical order in the lectures; this order has been respected in the present edition."

The text is ideal for under and postgraduate students of biophysical chemistry and as a handy guide for researchers in industry and biotechnology. This text covers: The study of biological cell and its organisation Bioenergetics Statistical Mechanics in biopolymers Forces involved in biopolymer interactions Cell membrane and solute transport Biopolymers and their molecular weights Thermodynamics of biopolymer solutions Diffraction methods and study of macromolecules

With global capacity in excess of 5 million tons annually, phenolic resins are one of the leading thermosetting resins that are used in many diverse industries such as wood adhesives, fiberglass/mineral wool binder, molded materials for autos/electronic/electrical industries, brakes, abrasives, foam, coatings/adhesives, laminates, composites, metal castings/refractories, and rubber industry. These phenolic resin business areas are critical to the national economy and general welfare of emerging and developed nations. Although phenolic resins are barely noticed in these applications, it is difficult to imagine their absence since they are vital and not easily replaced by other polymeric materials due to favorable cost/performance characteristics of phenolic resins.

In this new book these application areas are summarized and updated by global phenolic experts that are engaged daily in these activities. Further new technology and application areas of global technical activity are presented and include nanotechnology, updated phenolic resin chemistry, carbon fiber and long glass fiber reinforced molding materials, new analyses/testing, carbon foam, carbon/carbon brakes for autos, photo resists, new fiber reinforced systems, renewable raw materials, and recycling.

It is anticipated that the new book will feature a global perspective of phenolic resins through the participation of international (North America, Europe and Asia) phenolic experts that was lacking in all previous books related to phenolic resins.

Organometallic chemistry is an interdisciplinary science which continues to grow at a rapid pace. Although there is continued interest in synthetic and structural studies the last decade has seen a growing interest in the potential of organometallic chemistry to provide answers to problems in catalysis synthetic organic chemistry and also in the development of new materials. This Specialist Periodical Report aims to reflect these current interests reviewing progress in theoretical organometallic chemistry, main group chemistry, the lanthanides and all aspects of transition metal chemistry. Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research.

The conventional solvents used in chemical, pharmaceutical, biomedical and separation processes represent a great challenge to green chemistry because of their toxicity and flammability. Since the beginning of "the 12 Principles of Green Chemistry" in 1998, a general effort has been made to replace conventional solvents with environmentally benign substitutes. Water has been the most popular choice so far, followed by ionic liquids, surfactant, supercritical fluids, fluorous solvents, liquid polymers, bio-solvents and switchable solvent systems. Green Solvents Volume I and II provides a throughout overview of the different types of solvents and discusses their extensive applications in fields such as extraction, organic synthesis, biocatalytic processes, production of fine chemicals, removal of hydrogen sulphide, biochemical transformations, composite material, energy storage devices and polymers. These volumes are written by leading international experts and cover all possible aspects of green solvents' properties and applications available in today's literature. Green Solvents Volume I and II is an invaluable guide to scientists, R&D industrial specialists, researchers, upper-level undergraduates and graduate students, Ph.D. scholars, college and university professors working in the field of chemistry and biochemistry.

The dielectric properties especially of glassy materials are nowadays explored at widely varying temperatures and pressures without any gap in the spectral range from Hz up to the Infrared, thus covering typically 20 decades or more. This extraordinary span enables to trace the scaling and the mutual interactions of relaxation processes in detail, e.g. the dynamic glass transition and secondary relaxations, but as well far infrared vibrations, like the Boson peak. Additionally the evolution of intra-molecular interactions in the course of the dynamic glass transition is also well explored by (Fourier Transform) Infrared Spectroscopy. This volume within 'Advances in Dielectrics' summarizes this knowledge and discusses it with respect to the existing and often competing theoretical concepts.
