DESCRIPTION:Resonant diffraction techniques are used when standard “stan
 dard” powder or single crystal diffraction experiments are not providing
  a complete description of the crystal structure. In these anomalous scatt
 ering techniques the energy-dependence of the dispersion correction to the
  structure factor is crucial for the determination of the absolute structu
 re and to solve the phase problem in macromolecular crystallography. Moreo
 ver\, resonant scattering can be exploited to probe unoccupied states in t
 he valence band and hence help to determine the electronic properties of c
 ondensed matter. In this lecture the basics of resonant scattering are int
 roduced and highlighted on a few examples.
