X-ray crystallography is the primary method for determining the molecular conformations of biological macromolecules, particularly protein and nucleic acids such as DNA and RNA. In fact, the double-helical structure of DNA was deduced from crystallographic data. The first crystal structure of a...
X-ray crystallography is a form of elastic scattering; the outgoing X-rays have the same energy, and thus same wavelength, as the incoming X-rays, only with altered direction. By contrast, ''inelastic scattering'' occurs when energy is transferred from the incoming X-ray to the crystal, e.g., by...

Elastic vs. inelastic scattering X-ray crystallography is a form of elastic scattering; the outgoing X-rays have the same energy, and thus same wavelength, as the incoming X-rays, only with altered direction. By contrast, ”inelastic scattering” occurs when energy is transferred ...
Early scientific history of crystals and X-rays X-rays were discovered by Wilhelm Conrad Röntgen in 1895, just as the studies of crystal symmetry were being concluded. Physicists were initially uncertain of the nature of X-rays, although it was soon suspected ...
Cryo crystallography enables X-ray data collection at cryogenic, near liquid temperatures (also called: N2). #Crystals are transferred from mother liquor to a hydrocarbon environment #Crystals are mounted with a glass fiber (as opposed to a capillary) #Crystals are cooled with ... Crystallography is the experimental science of determining the arrangement of atoms in solids. The word “crystallography” is derived from the Greek words ”crystallon” = cold drop / frozen drop, with its meaning extending to all solids with some degree of ...
Crystallography is a tool that is often employed by materials scientists. In single crystals, the effects of the crystalline arrangement of atoms is often easy to see macroscopically, because the natural shapes of crystals reflect the atomic structure. In addition, ...
Some materials studied using crystallography, proteins for example, do not occur naturally as crystals. Typically, such molecules are placed in solution and allowed to crystallize over days, weeks, or months through vapor diffusion. A drop of solution containing the molecule, ...

X-ray crystallography has led to a better understanding of chemical bonds and non-covalent interactions. The initial studies revealed the typical radii of atoms, and confirmed many theoretical models of chemical bonding, such as the tetrahedral bonding of carbon in the ... Biophysics is an interdisciplinary science that uses the methods of physics and physical chemistry to study biological systems. Studies included under the branches of biophysics span all levels of biological organization, from the molecular scale to whole organisms and ecosystems. ...
