Single crystal diffraction


Determine the three-dimensional structure of molecules

When chemical or biological substances crystallize into single crystals, the technique of X-ray or electron diffraction can be used to determine their three dimensional structure. The technique provides accurate and precise measurements of molecular dimensions in a way that no other method can approach and is the only method for determining absolute structure unambiguously. A frequent use is the identification of natural products, or of the products of synthetic chemistry experiments; however, detailed molecular geometry, intermolecular interactions and absolute configuration can also be studied.
