• EXAFS Spectroscopy
  EXAFS (Extended X-ray absorption fine structure) refers to the sinusoidal variation of the X-ray absorption coefficient as a function of X-ray photon energy, which occurs after each absorption edge of an element and extends for up to 1500 eV further. This phenomenon forms the basis to the analytical technique of EXAFS spectroscopy, which can be used to obtain structural information about molecules without the need for obtaining single crystals. This is a short tutorial on the technique.
• Service Crystallography Special Interest Group
  The Service Crystallography Special Interest Group was formed to provide a forum for professional service crystallographers. The membership serves in both academia and industry and consists of both small-molecule and macromolecular crystallographers.
• Small Molecule Special Interest Group
  The Small Molecule Special Interest Group was formed to promote all aspects of the application of crystallographic techniques to the determination, analysis and presentation of structures of small molecules.
