WebThe aim of x ray crystallography is to obtain a three dimensional molecular structure from a crystal. A purified sample at high concentration is crystallised and the crystals are exposed to an x ray beam. The resulting diffraction patterns can then be processed, initially to yield information about the crystal packing symmetry and the size of the repeating unit that … WebOct 30, 2024 · X-Ray crystallography provides a two-dimensional view that gives an indication of the three-dimensional structure of a material Relatively cheap and simple Useful for large structures: Not...
