Use of intensity quotients and differences in absolute structure refinement

Differences and quotients can be defined using Friedel pairs of reflections and applied in refinement to enable absolute structure to be determined precisely even for light atom crystal structures.

TiGePt – a study of Friedel differences

By the use of R_merge factors on Friedel-difference intensities and the D-Patterson function, the structure of the intermetallic compound TiGePt is shown to be non-centrosymmetric.
