Rietveld Refinement & Indexing Course
Fall 2025
Powder pattern Indexing and Rietveld structural refinement techniques are complementary and are often combined to determine the structure of a material. Successful indexing of a powder pattern is considered strong evidence for phase purity.
“A good quality meeting that was well worth attending.”
Indexing (with derived space group and lattice symmetry determinations) is considered a prelude to determining the crystal structure, and permits phase identification by lattice matching techniques. The 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). The aim is to perform quantitative phase analysis and identification.
This course introduces the theory and formalisms of various indexing methods and structural refinement techniques. One unique aspect of this class is the extensive use of computer laboratory problem solving and exercises that teach method development in a hands-on environment. We will use GSAS-II for the Rietveld laboratory work; Dicvol, Treor and FULLPROF Suite and JADE interfaces will be used for indexing exercises.
The format of the course is a combination of morning lectures and afternoon computer lab exercises. Ample opportunity for individual student-faculty interaction exists throughout the week.Â
Lecture Components
Basic Crystallography
- Emphasis on space groups, conventions, and more.
Powder Pattern Indexing
- Data reduction methods for peak finding
- We will use Dicvol 04, Treor and Ito indexing examples
- Crysfire will also be discussed
Rietveld Structural Refinement
- History and motivation for development of this technique
- Qualitative description of various sample and instrument-related functions for profile shape, background, and more.
- The use of least-squares constraints will be explored
LeBail and Pawley Fitting Procedures
- What to do when atomic coordinates are not available
- Discussion on use of these tools for structure determination
- Use in powder pattern indexing
Computer Lab Components
Exercise problems will include:
- Single phase indexing
- Single phase refinement (all crystalline materials)
- Multiphase refinement (all crystalline materials)
- Nanophase, and small crystallite size content
- Amorphous phase + crystalline phase(s)
