X-ray diffraction patterns of BR crystals.
(a) Diffraction of a hexagonal crystal grown in MO cubic
phase. The circles drawn indicate resolutions of 3.1, 4.1, 6.2, and
12.4 Å, respectively, at 2ω = 6.1°. The diffraction limit of the
crystal is at a resolution of 3.7 Å. (b) Diffraction of
a rhombic crystal grown in MP cubic phase. The diffraction limit of
this crystal is at 9 Å. For details, see Materials and
Methods.
