Figure 9
Displacive correlations along the molecular chains in TPA, showing the correlations amongst components of displacements in the ab plane of polymorph (I), in a polar plot in which the angle, θ, gives the direction of the displacement component to the a axis and the radius gives the strength of the correlation. The view is the same as in Fig. 8[link](a), but the molecules in question are second nearest-neighbours, and the correlations are weak.
