Chemical Crystallography

Chemical crystallography is an application of diffraction techniques to the study of structural chemistry. A frequent purpose is the identification of natural products, or of the products of synthetic chemistry experiments; however detailed molecular geometry, inter molecular interactions and absolute configurations can also be studied. Different chemical Structures are studied as a function of temperature, pressure, application of electromagnetic radiation, magnetic or electric field: these kind studies comprises of only small minority of the total structures. The single crystal is used in x-ray diffraction to find the structure of a chemical compound that has been historically classified as 'Chemical Crystallography'. Most of these difficulties can be mostly overcome by employing more powerful radiation sources as the extent of diffraction depends on the number of electrons an atom has, and finding the positions of hydrogen atoms using X-ray diffraction can be difficult.
