Implementation and use of robust refinement in powder diffraction in the presence of impurities

K. H. Stone, S. H. Lapidus and P. W. Stephens

A modification to the usual least-squares analysis is implemented for the robust refinement of structural parameters from powder diffraction data in the presence of unmodeled impurities. This is accomplished in the program TOPAS-Academic by an iterative reweighting of the data as the model is refined. The method is tested and characterized using mixtures of known materials, acetaminophen and ibuprofen. The technique is also used to refine two previously unknown structures.

Keywords: least-squares analysis; Rietveld refinement; robust refinement; powder diffraction data; unmodeled impurities.
