TJ. X-ray crystallography is a tool used for identifying the atomic and molecular structure of a crystal, in which the crystalline atoms cause a beam of incident X-rays to diffract into many specific directions. By measuring the angles and intensities of these diffracted beams, a crystallographer can produce a three-dimensional picture of the density of electrons within the crystal. From this electron density, the mean positions of the atoms in the crystal can be determined, as well as their…
Stanford scientists find a new way to turn graphite into diamond By Dario Borghino April 2014 Diamond and graphite are both allotropes of carbon; their vastly different properties come down to the way the carbon atoms are arranged
An X-ray diffraction pattern of a crystallized enzyme. The pattern of spots (reflections) and the relative strength of each spot (intensities) can be used to determine the structure of the enzyme. X-ray crystallography - Wikipedia, the free encyclopedia
New tool puts LCLS X-ray crystallography on a diet
Vitamin B12. This crystal structure model, made for the X-ray crystallographer Dorothy Crowfoot Hodgkin, shows the structure of the hexacarbocylic acid fragment of Vitamin B12. It was displayed at the Brussels Universal Exhibition (�Expo�) in 1958. The full structure of this complex and large vitamin was determined by Hodgkin using X-ray crystallography in 1957, before chemists were able to work out using chemical means, and this model is a result of her work.
