Due to its interdisciplinary nature, crystallography is of major importance to a wide range of scientific disciplines including physics, chemistry, molecular biology, materials science and mineralogy. However, information is currently divided amongst traditional physics, chemistry and materials science books. This book collates previously disparate literature into one comprehensive and practical source, providing a thorough understanding of the information contained in crystallographic data files and the application of x-ray diffraction methods. The book has been written for final year and postgraduate students.
