(a) The experimental arrangement used to record diffuse scattering using high-energy X-rays ( Å). (b) A single frame of data for PCNB recorded with a 2 s exposure using a Mar345 Image-plate detector. 500 frames, recorded at intervals of of the crystal rotation, , were used for the complete three-dimensional set of data used in the study described in §3 . The dark region near the middle of the pattern is due to air scattering. This was subsequently subtracted during processing. The maximum recorded was 0.85 Å−1. |
