Definition
 
enEnglish
Rietveld Refinement definition: A least squares analysis that minimizes the differences between the calculated and measured values by adjusting the parameters needed to describe the model. It is used for POWDER DIFFRACTION crystallography.
 
deGerman
Veredelung definition: 'Veredelung' bedeutet [1] die Wertsteigerung von Materialien und Produkten durch intelligente Bearbeitung, Verarbeitung oder Ausbesserung, [2] die vegetative Vermehrung von Nutz- und Zierpflanzen mit Hilfe von Wirtspflanzen, [3] die charakterliche, sittliche und geistige Verbesserung der Menschen oder der Gesellschaft.
 
Examples
 

Methods and resources for obtaining chemically plausible starting models and restraint sets for refinement of ligand complexes are described and some of the potential pitfalls are discussed.

Model building and refinement of complexes between biomacromolecules and small molecules requires sensible starting coordinates as well as the specification of restraint sets for all but the most common non-macromolecular entities.

A communication problem caused confusion during the refinement of a complex of cellular retinoic acid-binding protein II with a synthetic retinoid that was supposed to be TTNPB (Fig.

The lack of data can to some extent be compensated for by the use of prior knowledge in the model refinement process.

Gerard J. Kleywegt

Acta Crystallographica Section D: Biological Crystallography 63 (Pt 1), 01 Jan 2007

Examples of constraints include the use of strict noncrystallographic symmetry (NCS), rigid-body refinement, refinement of overall or grouped temperature factors and model parameterization in torsion-angle space (in which bond lengths and angles can be kept fixed during refinement).
