Determine the three dimensional structure of molecules
Chemical or small molecule crystallography is a technique that employs single crystal X-ray diffraction (SCX) to unambiguously determine the three-dimensional structure of molecules. When molecules crystalize (think sugar) they form a three-dimensional regular arrangement of molecules. X-rays are diffracted by crystals and the diffraction pattern so created can be measured and analyzed to determine the atomic arrangements within the molecule being studied. The technique provides accurate and precise measurements of molecular dimensions in a way that no other method can approach. The technique may be applied to compounds of both chemical and biological interest, including new synthetic chemicals, catalysts, pharmaceuticals, and natural products. 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.
