Study Notes
Diffraction Image Reflections
- Two types of information can be extracted from the reflections (spots) in diffraction images
- The geometrical arrangement of the reflections provides information about the crystal lattice and its symmetry
- The intensity of the reflections provides partial information about the content of the crystal lattice/array
- The intensity information is incomplete, lacking the phases
