Crystal structure refinement with SHELXL - PubMed

Before exploring Rietveld refinement, it is necessary to establish a greater understanding of powder diffraction data and what information is encoded therein in order to establish a notion of how to create a model of a diffraction pattern, which is of course necessary in Rietveld refinement. A typical diffraction pattern can be described by the positions, shapes, and intensities of multiple Bragg reflections. Each of the three mentioned properties encodes some information relating to … WebOct 21, 2014 · The present paper is intended to explain the philosophical and crystallographic background to developments between 2008 and 2015 in SHELXL, the program in the SHELX system responsible for crystal structure refinement.
