Twinning: a revival in modern crystal structure determinations

The availability of area detectors and the devolepment of dedicated software make possible nowadays to detect twinning from a diffraction pattern and to recover the contribution of one individual crystal only. Often, however, the crystal solution of a twinned crystal is obtained just using the software facilities as a “black box”. A modern classification of twins and the influence of twinning on a diffraction pattern shall be discussed.
