Modern structural applications of crystallography make extensive use of statistical methods, in particular the probability density function (pdf) of the magnitude of the structure factor. Similarly, direct methods of phase determination have been responsible for much of the success of crystallography - methods based on properties of joint pdfs. This monograph, from two authorities in the field of structure factor statics, presents a survey of techniques and theories in this field of research in a self-contained and consistent way, with an emphasis on the probabilistic principles involved.

In crystal chemistry and crystal physics, the relations between the symmetry groups (space groups) of crystalline solids are of special importance. Part 1 of this book presents the necessary mathematical foundations and tools: the fundamentals of crystallography with special emphasis on symmetry, the theory of the crystallographic groups, and the formalisms of the needed crystallographic computations. Part 2 gives an insight into applications to problems in crystal chemistry. With the aid of numerous examples, it is shown how crystallographic group theory can be used to make evident relationships between crystal structures, to set up a systematic order in the huge amount of known crystal structures, to predict crystal structures, to analyse phase transitions and topotactic reactions in the solid state, to understand the formation of domains and twins in crystals, and to avoid errors in crystal structure determinations. A broad range of end-of-chapter exercises offers the possibility to apply the learned material. Worked-out solutions to the exercises can be found at the end of the book.

Our understanding of the properties of materials, from drugs and proteins to catalysts and ceramics, is almost always based on structural information. This book describes the new developments in the realm of powder diffraction which make it possible for scientists to obtain such information even from polycrystalline materials. Written and edited by experts active in the field, and covering both the fundamental and applied aspects of structure solution from powder diffraction data, this book guides both novices and experienced practitioners alike through the maze of possibilities.

This is the first book to provide a comprehensive treatment of theories and applications in the rapidly expanding field of the crystallography of modular materials. Molecules are the natural modules from which molecular crystalline structures are built. Most inorganic structures, however, are infinite arrays of atoms and some kinds of surrogate modules, e.g. co-ordination polyhedra, are usually used to describe them. In recent years the attention has been focused on complex modules as the basis for a systematic description of polytypes and homologous/polysomatic series (modular structures). This representation is applied to the modelling of unknown structures and understanding nanoscale defects and intergrowths in materials. The Order/Disorder (OD) theory is fundamental to developing a systematic theory of polytypism, dealing with those structures based on both ordered and disordered stacking of one or more layers. Twinning at both unit-cell and micro-scale, together with disorder, causes many problems, "demons", for computer-based methods of crystal structure determination. This book develops the theory of twinning with the inclusion of worked examples, converting the "demons" into useful indicators for unravelling crystal structure. In spite of the increasing use of the concepts of modular crystallography for characterising, understanding and tailoring technological crystalline materials, this is the first book to offer a unified treatment of the results, which are spread across many different journals and original papers published over the last twenty years.

'This book reviews the state of the art for determining the 'real' structure of matter' Zeitschrift Fur kristallographieThis book reviews the state of the art for determining the 'real' structure of matter. Nature does not stack atoms up in crystals in a perfect manner. Various types of 'mistakes' find their way into the arrangements of atoms in real crystals. These mistakes or defects determine the physical properties of a material and understanding them is critical to predicting a new materials properties. This book reviews the principal characterisation technique permitting us to measure the defect solid state: X-ray diffraction.

Crystallography and structure theory have recently received increasing interest due to their role in understanding biological structures, high-temperature superconductors, and effects on mineral properties related to changes in temperature and pressure. This text offers an account of the wide range of crystallography in various branches of science.The fundamentals, the most frequently used procedures, and experimental techniques are all described, and a number of appendices are devoted to more specialist aspects. The book is an updated edition with emphasis on the range of topical applications. Illustrations should help to clarify the subject matter. To provide a better understanding of the basics of crystallography, a compact disk has been added to this edition, offering the facilities of modern graphics to simulate experiments, show complex images, and provide a number of exercises.
