Rietveld refinement
Rietveld refinement is a scientific method used to extract precise information about the structure of a crystalline material from X-ray or neutron diffraction data. By comparing the observed diffraction patterns to a theoretical model, researchers adjust parameters like atomic positions, thermal vibrations, and phase percentages. The process iteratively refines the model to minimize the difference between the observed and calculated patterns. This technique helps scientists understand materials’ properties, such as their chemical composition and arrangement, which can be crucial in fields like chemistry, materials science, and geology.

Rietveld Refinement is a mathematical technique used to extract detailed information about the structure of crystalline materials from X-ray or neutron powder diffraction data. By modeling how X-rays scatter off the atoms in a crystal, scientists can determine the arrangement of those atoms, their types, and how they vibrate. This method refines multiple parameters simultaneously, adjusting them to best fit the experimental data. It's widely used in materials science and chemistry to analyze complex samples, aiding in the development of new materials, understanding chemical properties, and studying phase transitions.
