Diffraction images of crystal form B. (a) 1° oscillation image showing the direction of maximal diffraction. The h00 axis is approximately perpendicular to the strong layer lines. (b) 1° oscillation image showing the direction of minimal diffraction. The image is cropped at 8 Å. (c) 0.25° oscillation image optimized to show the diffuse scattering. The ring at 60 Å and the diffuse arcs at 4.2 Å are most likely to result from the presence of DPPC in the crystals. Similar features are observed for unoriented DPPC bilayers (McIntosh & Simon, 1986 ▶; Small, 1986 ▶).
