Rupp: Centric structure factors are centrosymmetrically related reflections that are additionally related by the point group symmetry of the crystal.< | Rupp: Centric structure factors are centrosymmetrically related reflections that are additionally related by the point group symmetry of the crystal.<br><br> | ||
Properties: centric reflections have only two phase possibilities, e.g. 0° and 180° (but in any case 180° apart), and centric reflections do not have an anomalous signal (can these properties be easily derived here?). | Properties: centric reflections have only two phase possibilities, e.g. 0° and 180° (but in any case 180° apart), and centric reflections do not have an anomalous signal (can these properties be easily derived here?). | ||
