Understanding Powder Diffraction Patterns

A powder diffraction pattern is a unique fingerprint of a crystal's atomic arrangement. By analyzing this pattern, we can reveal valuable information about the crystal's structure, composition, and physical properties.

The diffraction experiment involves directing a beam of X-rays or neutrons onto the crystal, resulting in the scattering of these particles. The scattered waves interfere with each other, producing a distinct pattern of constructive and destructive interference. This pattern is then recorded on a detector, typically in the form of a diffraction image or a graph.

Almost 50 years have passed since the famous papers of Hugo Rietveld from the late sixties where he describes a method for the refinement of crystal structures from neutron powder diffraction data. Soon after, the potential of the method for laboratory X-ray powder diffraction was discovered. Although the method is now widely accepted, there are still many pitfalls in the theoretical understanding and in practical daily use.

This book closes the gap with a theoretical for each chapter followed by a practical approach.The flexible macro type language of the Topas Rietveld software can be considered as the defacto standard.
