Rietveld Program

A Rietveld program is a specialized software used by scientists to analyze the detailed structure of crystalline materials. It works by comparing a theoretical pattern of X-ray or neutron diffraction—produced from a model of the material’s atomic arrangement—with actual experimental data. The program then adjusts the model's parameters to best fit the observed pattern, revealing precise information about the material's crystal structure, phase composition, and other properties. This method allows researchers to understand complex materials more accurately, facilitating advancements in materials science, chemistry, and geology.
