Advances in Structure Research by Diffraction Methods reviews advances in the use of diffraction methods in structure research. Topics covered include the dynamical theory of X-ray diffraction, with emphasis on Ewald waves in theory and experiment; dynamical theory of electron diffraction; small angle scattering; and molecular packing. This book is comprised of four chapters and begins with an overview of the dynamical theory of X-ray diffraction, especially in terms of how it explains all the absorption and propagation properties of X-rays at the Bragg setting in a perfect crystal. The next chapter describes the dynamical theory of electron diffraction, paying particular attention to unconventional structure analysis in connection with the problems of absorption. The most important features of the background of small angle analysis are then examined, and some examples showing the direct analysis of small angle scattering (sometimes in combination with wide angle scattering) are provided. The last chapter deals with crystals built from molecules and their peculiar geometrical features. The principle of close packing of molecules in an organic crystal is also described, along with lattice dynamics, hydrogen bonds in crystals, and the rotational crystalline state. This monograph will be a useful resource for practitioners and researchers in physics and crystallography.
