The reports investigates the propagation of light in the visible region through a crystalline medium. In Part I, the objective is to determine if the anisotropic arrangement of ordinary (isotropic) dipoles at the nodal points of an orthorhombic lattice would account for the existence of double refraction. Some features of the traditional 'theory of dispersion' are disclosed and clarified. In part II, a crystalline medium is considered as filling a half- space and having a plane boundary at z=0. A plane optical wave is incident on this medium. Because of the linearity of the equations it has to be superimposed on the field originating in the crystal. It is shown that this incident optical wave is actually prevented from entering the crystal because of the modification produced in the field of the crystal by the introduction of a boundary. Material Added 1970. The conclusion that the incident optical field cannot penetrate the crystal boundary, together with a similar conclusion in a paper by Oseen, is the basis of the Ewald-Oseen Extinction Theorem.

This book invites you on a tour through the most relevant topics of solid-state chemistry. It provides an up-to-date overview about fascinating structures of inorganic matter and new research developments. The reader will also gain crucial insights into many aspects of material science, from ceramics to superconductors. One chapter is specifically dedicated to the most rapidly evolving field of material science: metal-organic frameworks (MOFs). The book contains a chapter which is often neglected in others due to its complexity, the intermetallic phases. A concise but very didactic introduction to crystallographic specifications ensures that the reader will gain a deeper understanding of the crystal structures presented in the book. The book places special emphasis on the graphical illustrations which were specifically designed to promote real insights into the structural features. Instead of having to decipher hard to distinguish graphics the reader has an eye-opening experience. A further added value is that many references to the original research publications are given which enables easy follow-up for more detailed study.

This work presents a novel pure structural classification of minerals, based on the minerals' internal structure. In more detail, it is based on the strength distribution and directional character of the bonds. This new classification may be considered as an extension of the structural classification of silicates, to the complete domain of minerals. A complete and well organized overview of 230 mineral structure types comprizing the more common minerals is presented in chart form. On the charts, the crystal structures are presented in a number of complementary ways such as in projection, close packing, coordinated polyhedra and layer description. This work is of particular interest to teachers and research workers in crystallography, mineralogy and inorganic crystal chemistry in academia.

This unique and practical book provides quick and easy access to data on the physical and chemical properties of all classes of materials. The second edition has been much expanded to include whole new families of materials while many of the existing families are broadened and refined with new material and up-to-date information. Particular emphasis is placed on the properties of common industrial materials in each class. Detailed appendices provide additional information, and careful indexing and a tabular format make the data quickly accessible. This book is an essential tool for any practitioner or academic working in materials or in engineering.

Zusammenfassung: This textbook introduces readers to the language, concepts, and tools of crystallography, as well as many aspects of crystal chemistry. Important topics, such as bonding, electronegativity, lattice energy, symmetry operations, crystal defects, and structure-property relationships are covered. Worked examples are included where appropriate. By uniquely combining elements of crystallography and crystal chemistry, the text is a useful and accessible resource for students across many disciplines. Chapter summaries and example problems are included to optimize use by students and faculty in both graduate and undergraduate curricula. Historical context to relevant discoveries and biographical sketches of many of the scientists involved in the development of this field are also provided to expand the student's knowledge of both solid-state science and scientists. Details how crystallography can be used to better understand the structure-property relationships of materials; Includes worked examples to reinforce topics explored; Provides a comprehensive examination of crystallography, crystal chemistry, and the overlap between the two

At the time of its establishment in 1966, by the International Council of Scientific Unions (ICSU), the Committee on Data for Science and Technol ogy (CODATA) was given the basic mission of promoting and encouraging, on a worldwide basis, the production and distribution of compendia and of collections of critically selected numerical data on substances other forms of interest and importance to science and technology. To accomplish this aim, the following tasks were assigned to CODATA: (1) To ascertain, on a worldwide basis, what work on compilation of numerical data is being carried on in each country and under each union, and from this information, to prepare and distribute a Directory or Com pendium of the Data-Compiling Projects and Related Publications of the World; (2) To achieve coordination of existing programs and to recommend new programs; (3) To encourage, from all appropriate sources, financial support for work on compilation; (4) To encourage the use of internationally approved symbols, units, constants, terminology, and nomenclature; (5) To encourage and coordinate research on new methods for preparing and disseminating data for science and technology. In its first two years of operation, 1966 to 1968, in Washington, D. c. , U. S. A. , CODATA fortunately had as its Director Dr. GUY WADDINGTON, who was also Director of the Office of Critical Tables of the National Research Council (NRC), U. S. A. Dr.
