Book Description
Polymorphism - the multiplicity of structures or forms - is a term that is used in many disciplines. In chemistry it refers to the existence of more than one crystal structure for a particular chemical substance. The properties of a substance are determined by its composition and by its structure. In the last two decades, there has been a sharp rise in the interest in polymorphic systems, as an intrinsically interesting phenomenon and as an increasingly important component in the development and marketing of a variety of materials based on organic molecules (e.g. pharmaceuticals, dyes and pigments, explosives, etc.). This book summarizes and brings up to date the current knowledge and understanding of polymorphism of molecular crystals, and concentrates it in one comprehensive source. The book will be an invaluable reference for students, researchers, and professionals in the field.

Book Description
Organic Solid-State Chemistry–2 presents the solid state reactions in molecular crystals. This book discusses the correlations of the chemical structures of products from organic solid state reactions with the molecular packing in the reactant crystal structures. Organized into 10 chapters, this book begins with an overview of the molecular behavior after the chemical transition state. This text then examines the electron paramagnetic resonance methods, which offer many features in connection with the study of chemical reactions in which a paramagnetic species is a product or a reactant. Other chapters consider the interpretation of radiationless transitions, thermal reactions, and photochemical decompositions and rearrangements. The final chapter deals with the experimental results concerning electron and hole production in anthracene crystals, with emphasis on the relevance of these studies to the fundamental question of the nature of the excess electron states in these low mobility crystals. This book is a valuable resource for solid state chemists, photochemists, spectroscopists, scientists, and research workers.

Book Description
Reporting on advances in the field of molecular solid state chemistry, each volume focuses on selected areas and highlights methods and results in syntheses, properties and applications. The volumes in this series provide a forum for the discussion of chemical, physical, biological and crystallographic aspects of the molecular solid state. Eight chapters focus on the theoretical aspects of the reactivity of solids and the applications that are of practical importance. In a collection of reviews that highlight hot topics in the field of molecular solids, the authors of this volume emphasise the problems facing them. Contents: Interplay between Intra- and Intermolecular Interactions in Solid-State Reactions Cooperative Effects in Solid State Reactions Some Aspects of Bimolecular Photoreactions in Crystals Kinetics and Spatial Propagation of Intramolecular Reactions in Solids Kinetic Descriptions of the Simplest Bimolecular Reactions in Organic Solids Radical Solid-State Reactions at High Pressure Polymorphs and Solvates of Molecular Solids in the Pharmaceutical Industry Mechanochemical Synthesis and Mechanical Activation of Drugs. Reactivity of Molecular Solids will be of interest to all chemists working in the pharmaceutical, fine chemicals and food industries, and also in molecular electronics and materials science.

Book Description
With the growing recognition that many organic reactions may be conducted easily in the solid state and that organic solids may have unique optical/electronic properties, there has been much interest - in both academia and industry - in the subject of organic solid state chemistry. This book provides, for the first time, a coherent, unified view of the subject. It describes the packing of molecular crystals and how this packing influences chemical reactions in the solid state. It is concerned with various means of studying the chemistry and physics of molecules in constrained environments. Both experimental and theoretical approaches are discussed. Finally, it tackles the question of prediction of crystal packing, or crystal engineering'. The strength of the book lies in the twin approach adopted, namely that both conceptual and comprehensive chapters are present, in almost equal numbers.

Book Description
The theoretical aspects of crystal packing, the study of the nature and magnitude of the forces that hold molecules together in organic crystals, and of the most favourable arrangements of molecules in crystals are dealt with in this book. After an introductory chapter on the definition and relevance of symmetry in crystal packing, a chapter deals with the physical foundations of weak intermolecular forces and with their simulation by quantum chemical methods. Subsequently, the relationships between crystal structure and crystal thermodynamics are described using empirical intermolecular potentials to bridge the gap by computer modelling.
