The deduction of crystal structure from analysis of the diffraction pattern of X-rays passing through a pure crystal of a substance.
A technique, using X rays, to determine the atomic structure of molecules that have been crystallized. A technique for deducing molecular structure by aiming a beam of X rays at a crystal of the test compound and measuring the scatter of rays.
Determination of three dimensional arrangement of atoms in a crystal by analysis of x-ray diffraction patterns.
A technique that enables scientists to decipher the 3-D structure of molecules. It depends on obtaining a crystal of the molecule and subjecting the crystal to x-rays. The structure of the molecule can then be deciphered from the pattern of x-ray scattering off atoms in the crystal.
X-ray photographs of metals are a means of providing information which in many cases cannot be obtained by microscopic methods. The lines produced by each element, or phase are characteristic, and their general pattern enables the crystalline structure to be identified. The scale of the pattern can be used to determine accurately the size of the unit cell and, therefore, the distance apart of the individual atoms. From the relative intensity of the lines it is possible to deduce the distribution throughout the unit cell, the various types of atoms in an alloy or the degree of preferred orientation in the material.
A technique for determining the 3-D structure of a molecule, based on the diffraction of x-rays by the crystallized form of the molecule. Computational analysis of the diffraction pattern produces an electron density map that is optimized using sequence i
A technique used to determine the detailed, three-dimensional structure of molecules based on the scattering of X-rays through a crystal of the molecule.
A technique for studying molecular and atomic structure of a substance.
A technique used to determine protein structure in which proteins in a crystalline form are exposed to X-rays. Advanced computer programs are then used to analyze the patterns of the X-rays bending throu...
A technique for determining the three-dimensional structure of a large molecule, such as a protein.
Study of the molecular structure of crystalline compounds through X-ray diffraction techniques. When an X-ray beam bombards a crystal, the atomic structure of the crystal causes the beam to scatter in a specific pattern.
an essential technique for determining the three-dimensional structure of biological molecules.
X-ray crystallography is a technique in crystallography in which the pattern produced by the diffraction of X-rays through the closely spaced lattice of atoms in a crystal is recorded and then analyzed to reveal the nature of that lattice. This generally leads to an understanding of the material and molecular structure of a substance. The spacing in the crystal lattice can be determined using Bragg's law.
