Crystals have fascinated us for centuries with their beauty and symmetry, and have often been invested with magical powers. The use of X-ray diffraction, first pioneered in 1912 by father and son William and Lawrence Bragg, enabled us to probe the structure of molecules, and heralded the scientific study of crystals, leading to an understanding of their atomic arrangements at a fundamental level. The new discipline, called X-ray crystallography, has subsequently evolved into a formidable science that underpins many other scientific areas. Starting from the determination of the structures of very simple crystals, such as that of common salt, today it has become almost routine to determine the positions of tens of thousands of atoms in a crystal. In this Very Short Introduction Mike Glazer shows how the discoveries in crystallography have been applied to the creation of new and important materials, to drugs and pharmaceuticals and to our understanding of genetics, cell biology, proteins, and viruses. Tracing the history of crystallography, he analyses astonishing developments in new sources of X-rays, as well as of neutrons, and in electron microscopy, and considers the impact they have on the study of crystals today. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable. Read more

For researchers obtaining their first crystal structure.Small molecule X-ray crystallography can be divided into two separate areas - the mathematical background on how it all works, and the actual practical application of the technology as provided by a crystallography lab (for example, in an university environment). This short introductory guide concentrates on the latter. Most chemists who encounter crystallography do not necessarily need to know the physics behind diffraction, but would gain from a brief overview of the topic with emphasis on the aspects relevant to using the technique to compliment & benefit their own research.What follows is a short summary covering the process of obtaining a crystal structure - from techniques of crystal growing to what happens after a crystal is submitted to a lab. The aim is to enlighten research chemists about:•the difference between a good quality and poor quality dataset•how to look at the structure of your molecule•understand the terms asymmetric unit & unit cell•identify basic symmetry elements and interactions •where to start when presenting the dataAn overview of a complex topic intended for postgraduate students encountering small molecule X-ray crystallography in their research for the first time – hopefully brief & light enough to digest quickly.Contents:IntroductionWhat is a crystal?What is twinning?Growing crystals: keep it simpleSlow evaporationVapour diffusionLayeringSolubilityPersistenceWhat size crystals do I need?How do I know if my crystals are good enough?How do we see objects?How can we see a molecule?What is an X-ray diffractometer?Types of diffractometersWhat is a unit cell?What is an asymmetric unit?What is a symmetry element?What is a space group?Solving a crystal structure - the processWhy is my structure poor quality?Resolution, why structures look badDisorderNumber analysis – what is a decent R factor?Why isn’t my structure publishable?What can I do if I have a bad structure?How to open a cif file and look at your structureInteractionsTips for writing up or presenting a structureCheckcif reports and CCDC deposition numbersWhat can you say about a poor quality structure?Conclusion Read more

*Shortlisted for the Duff Cooper Prize and the Marsh Biography Award*The definitive biography of chemist Dorothy Crowfoot Hodgkin, the only British woman to win a Nobel prize in the sciences to date. Dorothy Crowfoot Hodgkin (1910–1994) was passionate in her quest to understand the molecules of the living body. She won the Nobel Prize for Chemistry in 1964 for her work on penicillin and Vitamin B12, and her study of insulin made her a pioneer in protein crystallography. Fully engaged with the political and social currents of her time, Hodgkin experienced radical change in women's education, the globalisation of science, relationships between East and West, and international initiatives for peace. Georgina Ferry's definitive biography of Britain's first female Nobel prizewinning scientist was shortlisted for the Duff Cooper Prize and the Marsh Biography Award. This revised and updated edition includes a new preface from the author. Read more

Because symmetry arguments are a powerful tool in teaching such concepts as hybridization, group and molecular orbitals, selection rules in absorption spectroscopy, crystal structure, and other topics, a book devoted exclusively to symmetry in chemistry, developed in an essentially nonmathematical way, is a must for students and research workers interested in these subjects. This is such a book. After an introduction to symmetry, the authors offer lucid discussions of symmetry elements and operations, multiple symmetry operations, multiplication tables and point groups, group theory, applications, and crystal symmetry. Three appendices provide complete character tables, tables of the number of normal vibrations in various symmetry species, and tables showing the direct sums of excited states and combination states of degenerate vibrations. Intended as a supplementary text for both undergraduate and graduate students who seek a broad background for understanding structural problems, this concise treatment will also appeal to the large group of practicing chemists who wish to review the applications of symmetry and group theory.

This book provides a clear and very broadly based introduction to crystallography, light, X-ray and electron diffraction - a knowledge which is essential to students in a wide range of scientific disciplines but which is otherwise generally covered in subject-specific and more mathematically detailed texts. The text is also designed to appeal to the more general reader since it shows, by historical and biographical references, how the subject has developed from the work and insights of successive generations of crystallographers and scientists.The book shows how an understanding of crystal structures, both inorganic and organic may be built up from simple ideas of atomic and molecular packing. Beginning with (two dimensional) examples of patterns and tilings, the concepts of lattices, symmetry point and space groups are developed. 'Penrose' tilings and quasiperiodic structures are also included. The reciprocal lattice and its importance in understanding the geometry of light, X-ray and electron diffraction patterns is explained in simple terms, leading to Fourier analysis in diffraction, crystal structure determination, image formation and the diffraction-limited resolution in these techniques. Practical X-ray and electron diffraction techniques and their applications are described. A recurring theme is the common principles: the techniques are not treated in isolation.The fourth edition has been revised throughout, and includes new sections on Fourier analysis, Patterson maps, direct methods, charge flipping, group theory in crystallography, and a new chapter on the description of physical properties of crystals by tensors (Chapter 14).
