|Abstract:||Single-crystal neutron diffraction allows determination of the distribution of nuclear scattering density in crystalline structures. It is especially suited to the location of hydrogen and characterization of hydrogen bonding in structures ranging from ice to small proteins, to the determination of magnetic structures, and to experiments on crystals under extreme conditions of temperature, magnetic field, and pressure. The principal requirement is a good quality single crystal of volume 0.1–10 mm3, although ongoing instrumental developments, including the introduction of large area detectors and Laue methods, are continually decreasing the lower limit. There are currently over 30 dedicated single-crystal neutron diffractometers at steady-state reactor and neutron spallation sources worldwide, accessible via peer-reviewed proposal mechanisms. The experimental and analysis techniques are well established and are very similar to those used for single-crystal x-ray diffraction. © 2012 John Wiley & Sons, Inc.|
