Space Groups: A primer on topics significant for powder diffraction
Presentation Goal
- Introduce symmetry concepts important for Rietveld analysis,
particularly of inorganic materials.
Knowledge of symmetry operations and space groups,
as covered in any crystallography textbook, is assumed.
- Format: PDF slides or a RealPlayer video of the slides with
accompanying audio
