→Reciprocal space
(New page: Centric reflections play the same role in reciprocal space as special positions in real space: they may occur at the borders of the asymmetric unit. It makes sense to discuss the reciproca...) |

Centric reflections in space group P2 and P2_1 are thus those with 0,k,0. | Centric reflections in space group P2 and P2_1 are thus those with 0,k,0. | ||
Properties: centric reflections have only two phase possibilities, e.g. 0° and 180°. Furthermore, centric reflections do not have an anomalous signal. (can these properties be easily derived here?) | |||
There exist space groups without centric reflections, like R3. | |||
