(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. |
