Opis

International Tables for Crystallography is the definitive resource and reference work for crystallography and structural science. Each of the eight volumes in the series contains articles and tables of data relevant to crystallographic research and to applications of crystallographic methods in all sciences concerned with the structure and properties of materials. Emphasis is given to symmetry, diffraction methods and techniques of crystal-structure determination, and the physical and chemical properties of crystals. The data are accompanied by discussions of theory, practical explanations and examples, all of which are useful for teaching. Volume E covers the standard nomenclature and representations for the 7 crystallographic frieze-group types, the 75 crystallographic rod-group types and the 80 crystallographic layer-group types. The information tabulated for these groups is identical in format and content to that given for the 230 space groups in Volume A, and is essential for the analysis of the structure and physical properties of crystalline materials that contain linear or planar substructures. In addition, scanning tables are given for each of the 230 space groups, designed for use in the analysis of interfaces. This second edition of Volume E has been revised and includes additional information in the comparison tables of notations for the subperiodic group types to improve ease of use. The Seitz notation of each symmetry operation has also been included.
