Figure 3
Observed data, measured at the Advanced Photon Source, for TPA triclinic polymorph (I) at 295 K. The yellow arrow on (a) indicates a (weak) streak due to molecular chains (direction indicated by white double arrow). Yellow arrows on (b) indicate artefacts due to the intense scattering near a large Bragg peak, and also a spot due to a second crystalite. (a) 0kl, (b) h0l, (c) hk0. Reconstructions proved difficult in this case. Black areas indicate a lack of data. The extent of data is similar to the extent of the calculation in Fig. 7. |
