Figure 4
A twinned diffraction pattern of nollmotzite. A precession-like image (left) of reciprocal space, reconstructed with the UNWARP procedure of the CrysAlis software, h3l plane and (right) the same diffraction pattern calculated using Jana2006 from the structure model determined here. Yellow spots belong to the first (larger) domain (with the corresponding lattice shown with black lines), while green spots belong to the second (weaker) twin domain (with the corresponding lattice drawn with the green lines). |
