X-ray Diffraction (XRD)






Basic Theory: Crystallography

Utilization of X-Ray Diffraction

Crystallography: Diffraction data provides information on the structures of crystalline solids

  • The symmetry in structures shows itself in the diffraction by the appearance and disappearance of characteristic reflections. 

  • The intensity of the diffracted beams depends on the arrangement and atomic number of the atoms in the repeating motif, called the unit cell.  Unit cells describe the symmetry of all structures.
