This book is intended primarily for those readers, especially beginning research students, who wish to use X-ray diffraction to investigate specimens which may not be crystalline. Beginners need to understand how interference effects arise in X-ray diffraction patterns and the underlying principles involved in developing structural models. A general approach to these topics, and diffraction geometry, appears in the first four chapters of the book. Next the general ideas are applied to the scattering of X-rays by isolated atoms and molecules. In subsequent chapters the ways in which interference modifies the pattern of scattered X-rays, when the atoms and molecules aggregate in various states of energy, are considered. Such states of matter includes liquids, morphous solids and liquid crystals as well as crystals. Each state gives rise to characteristic interference effects which influence the appearance and any subsequent analysis of the resulting X-ray diffraction pattern. The final chapter demonstrates that the interpretation of X-ray diffraction patterns is simply an application of physical optics.
