Figure 1
Isomorphism and sampling of the molecular transform. Reciprocal-lattice point positions for pairs of unit cells with differing unit-cell parameters are compared. Each panel shows two sets of reciprocal-space lattices for unit cells of lengths 100 Å and (a) 103 Å or (b) 110 Å. Grey shading indicates the molecular transform. Thicker lines highlight positions where lattice points sample the same part of the molecular transform, with labels indicating their indices. The panels illustrate how non-isomorphism alters the sampling of the molecular transform and consequently the correlation between intensities at matched reciprocal-lattice indices.
