WebApr 9, 2024 · X-ray powder diffraction is a vital analytical tool that is used in pharmaceutical science. It is increasingly used to establish the crystal structure of a new pharmaceutical substance, in particular, cocrystal or its polymorphic forms. This review begins with a brief discussion of the reliability of the structural parameters retrieved from powder patterns. WebGeos 306, Lecture 11. Crystallography III, X-ray Diffraction. One of the most important consequences of the translational periodicity displayed by crystals is that crystals can be easily studied by X-ray diffraction. In fact, the International Union of Crystallography defines crystals as substances that produce sharp X-ray diffraction patterns.
