Combined Rietveld Refinements: Where 1+1 can be > 2
- Discuss why use of more than one data set, for example x-rays and neutrons or x-ray measurements can support more extensive models than that from a single data set. Or, how to use a priori "knowledge" (in truth, assumptions) to reduce the complexity of a model. Also, how to detect that two data sets are incompatible, where a combined fit is not appropriate.
- Format: PDF slides or a RealPlayer video of the slides with accompanying audio.
- Motivation to use more than a single measurement
- Anomalous dispersion (resonant scattering)
- X-rays + neutrons
- Hard & soft constraints
- Combined refinement case studies
- What can go wrong with combined refinements
- Slides (as PDF file)
