Diffraction

The X-ray photograph is merely a scaled-up sampling of the diffraction pattern of the contents of a single unit cell
Glusker & Trueblood - Crystal structure analysis - 1985

The intensity of each reflection depends on the presence of molecular motifs and is determined by the contents of the unit cell of the crystal
Rupp - Biomolecular Crystallography - 2010
