WebAbstract A novel approach to the determination of crystallite size and lattice strain by means of Total Pattern Analysis is described. Parameters to define the position, magnitude, breadth and shape of individual peaks are obtained by an adaptation of the pattern fitting program of Sonneveld and Visser (J. Appl. Cryst. 8, 1–7, 1975). A rapid assessment of … WebThe Rietveld method is used to refine crystal structures and is perhaps best considered whole- pattern-fitting structure refinement, i.e., we must account not only for the crystal structure but also the instrumental resolution and diffraction physics effects (e.g., crystallite size and strain).
