Text extracted from opening pages of book: CHEMICAL CBYSTALLOGRAPHY AN. INTRODUCTION TO OPTICAL AND X-RAY METHODS BY C. W. BUNN OXFORD AT THE CLARENDON PRESS Oxford University Press, Amen House, London E. G. 4 GLASGOW NEW YORK TORONTO MELBOURNE WELLINGTON BOMBAY CALCUTTA MADRAS CAPETOWN Geoffrey Cumberlege, Publisher to the University FIRST PUBLISHED 1045 REPRINTED WITH CORRECTIONS 1946 Reprinted lithographically in Great Britain at the UNIVERSITY PRESS, OXFORD, 1948, 1949, 1952, from corrected sheets of the second impression PREFACE CEYSTALLOGRAPHIC methods are used in chemistry for two main pur poses the identification of solid substances, and the determination of atomic configurations ; there are also other applications, most of which, as far as technique is concerned, may* be said to lie between the two main subjects. This baok is intended to be a guide to these methods. I have tried to explain the elementary principles involved, and to give as much practical information as will enable the reader to start using the methods described. I have not attempted to give a rigorous treat ment of the physical principles: the f approach is consistently from the chemist's point of view, and physical theory is included only in so far as it is necessary for the general comprehension of the principles and methods described. Nor have I attempted to give an exhaustive account of any subject ; the aim throughout has been to lay the founda tions, and to give sufficient references ( either to larger works or to original papers) to enable the reader to follow up any subject in greater detail if he so desires. The treatment of certain subjects is perhaps somewhat unorthodox. Crystal morphology, for instance, is described in terms of the concept of the unit cell ( rather than in terms of the axial ratios of the earlier morphologists), and is approached by way of the phenomena of crystal growth. The optical properties of crystals are described solely in terms of the phenomena observed in the polarizing microscope. X-ray diffrac tion is considered first in connexion with powder photographs; it is moj* e usual to start with the interpretation of the diffraction effects of single crystals. These methods of treatment are dictated by the form and scope of the book ; they also reflect the course of the writer's own experience in applying crystallographic methods to chemical problems. It is therefore hoped that they may at any rate seem natural to those to whom the book is addressed - students of chemistry who wish to acquire some knowledge of crystallographic methods, and research workers who wish to make practical use of such methods. If the book should come to the notice of a more philosophical reader, I can only hope that any qualms such a reader may feel about its avoidance of formal physical or mathematical treatment may be somewhat offset by the interest of a novel, if rather severely practical, viewpoint. The difficulties of three-dimensional thinking have, I hope, been lightened as much as possible by the provision of a large number of vi PREFACE diagrams ; but crystallography is emphatically not a subject which can be learnt solely from books: solid models should be used freely models of crystal shapes, of atomic . nd molecular configurations, of reciprocal lattices and of vectorial representations of optical and other physical properties. Most of the diagrams are original, but a few have been reproduced, by permission, from published books and journals: Figs. 197, 207-9, 215, and 222 from the Journal of the Chemical Society ; Figs. 199, 203, and 217 from the Proceedings of the Royal Society, Figs. 102-4 from the Journal of Scientific Instruments ; Fig. 229 from the Journal of the American Chemical Society, Fig. 161 from Inter nationale Tabetten ftir Bestimmung von Kristallstrukturen ( Berlin: Born traeger); Fig. 192 from the * Strnkturbericht ' of the Zeitschrift fttr Kristallographie\ and Figs. 212 and 216 from Bragg's The Crystalline State ...

Product Description

The International Tables for Crystallography are jointly published with the International Union of Crystallography. Each print volume can be purchased individually. In addition the complete set of Vol A-G is available both in print and online (see right hand column).

Volume A1 presents a systematic treatment of the maximal subgroups and minimal supergroups of the crystallographic plane groups and space groups. It is an extension of and a supplement to Volume A, Space-group symmetry, in which only basic data for sub- and supergroups are provided.

Volume A1 consists of three parts. Part 1 presents an introduction to the theory of space groups at various levels and with many examples. It includes a chapter on the mathematical theory of subgroups. Part 2 gives for each plane group and space group a complete listing of all maximal subgroups and minimal supergroups. The treatment includes the generators of each subgroup as well as any necessary changes of the coordinate system. Maximal isomorphic subgroups are given in parameterized form as infinite series because of the infinite number for each group. Graphs that illustrate the group-subgroup relations are also presented. Part 3 lists the relations between the Wyckoff positions of every space group and its subgroups. Again, the infinite number of maximal isomorphic subgroups of each space group are covered by parameterized series.

Volume A1 is a valuable resource for scientists engaged in crystal-structure determination, crystal physics or crystal chemistry. It is essential for those interested in phase transitions, the systematic compilation of crystal structures, twinning phenomena and related fields of crystallographic research.

Product Description
". . . heartily recommended to every crystallographer, students of crystallography and other solid-state scientists."--Acta Crystallographica While there are many excellent treatises on crystallography, few of them offer adequate instruction on vector and tensor manipulations in general coordinate systems, and even fewer include the specific examples and applications that crystallographers need. This hardcover graduate-level text is the exception. It offers excellent coverage of vectors and tensors for crystallographers, students of crystallography and solid-state scientists who need proficiency in carrying out calculations in rectilinear coordinate systems. The emphasis is on crystallographic applications, but the methods developed are essential in any problems that pertain to nonorthogonal systems. Unabridged and corrected Dover republication of the edition published by Addison-Wesley Publishing Company, Reading, Mass., 1982. 30 black-and-white illustrations. Preface. Glossary of symbols. Index. Bibliography. Exercises and solutions.

An excellent introduction for new crystallographers
This Dover reprint of "Vectors and Tensors in Crystallography" by Donald Sands is a wonderful single volume introduction to basic vector and tensor methods as applied to crystallography.All the basics of vectoroperations are clearly explained in chapter 1.Chapter two moves on tovector descriptions of lines, planes and projections.Three moves on totransformations, especially rotations and coordinate transformations.Thefirst three chapters lay a solid foundation for chapter 4, a concise vector& tensor based development of symmetry, working up to the derivation ofspace groups.Chapter 6 has the most practical & useful information:the various geometries used in diffraction experiments.This text is anexcellent resource for those new to crystallography or wanting to moredetail than the absolute basics.In particular, this text would be idealfor a crystallographer moving into the field from a biology undergraduatebackground who may need a little review of the basics of vector operationsbefore moving on to more advanced topics covered later in the text ordealing with the level of detail in The International Tables for x-rayCrystallography.Worked exercises are provided for most sections to aidself-study. ...

Product Description
Macromolecular Crystallography is the study of macromolecules (proteins and nucleic acids) using X-ray crystallographic techniques in order to determine their molecular structure. The knowledge of accurate molecular structures is a pre-requisite for rational drug design, and for structure-based function studies to aid the development of effective therapeutic agents and drugs. The successful determination of the complete genome (genetic sequence) of several species (including humans) has recently directed scientific attention towards identifying the structure and function of the complete complement of proteins that make up that species; a new and rapidly growing field of study called 'structural genomics'. There are now several important and well-funded global initiatives in operation to identify all of the proteins of key model species. One of the main requirements for these initiatives is a high-throughput crystallization facility to speed-up the protein identification process. The extent to which these technologies have advanced, calls for an updated review of current crystallographic theory and practice. This practical reference book features the latest conventional and high-throughput methods, and includes contributions from a team of internationally recognized leaders and experts. It will be of relevance and use to graduate students, research scientists and professionals currently working in the field of conventional and high-throughput macromolecular crystallography. ...

Product Description
For many years it was believed that translational symmetry would be the fundamental property of crystal structures of natural and synthetic compounds. It is now recognised that many compounds crystallise without translational symmetry of their atomic structures. "Incommensurate Crystallography" gives a comprehensive account of the superspace theory for the description of crystal structures and symmetries of these incommensurately modulated crystals and incommensurate composite crystals. It thus provides the necessary background for quantitative analysis of incommensurate crystals by methods in Solid State Chemistry and Solid State Physics. The second half of "Incommensurate Crystallography" is devoted to crystallographic methods of structural analysis of incommensurate compounds. Thorough accounts are given of the diffraction by incommensurate crystals, the choice of parameters in structure refinements, and the use of superspace in analysing crystal structures. The presentation of methods of structure determination includes modern methods like the Maximum Entropy Method and Charge Flipping. ... Read more

Product Description
This volume aims to explain the basic concepts of crystallography and to discuss the principal modes of study of crystalline solids and the diffraction of X-rays, electrons and neutrons. Some depth of understanding of crystallography and some knowledge of the methods employed in the study of crystalline solids are central to the contemporary study of many of the active areas in chemistry, the earth sciences, materials science and physics, and this book will therefore be of interest to students and researchers in those fields where crystallography applies. A notable feature of the book is the inclusion of problems at the end of each chapter. It is the first volume in the series "Crystalline Solids". ... Read more
