Figure 3
Diffuse scattering along c*. (a) Reciprocal space reconstruction of h0l layer and zoomed in at the area of the yellow box. Intensities are on the same scale as in Fig. 2 ![[link]](../../../../../../logos/arrows/iucrx_arr.gif) (a). Streaks are observed along c*, but much weaker than those along a* + b*. (b) Model of a single domain in which one layer is replaced by a rotation copy generated by the NCS rotation operation, which coincides with the twinning, i.e. 180° rotation around a* + b*. The colouring of the chains is the same as in Fig. 1, but the asymmetric unit used here (indicated by an ellipse) is such that the loops are on the outside. Inclusion of a layer of rotated copies will disrupt the periodicity perpendicular to the ab layer which is the c* direction, leading to diffuse streaks in the diffraction pattern. |
