(XRD) X-ray diffraction results from the interference of X-rays scattered by the electrons surrounding atoms. When the atoms form a regular array of repeating units, as in crystalline material, diffraction maxima are usually distinct. For disordered matter such as amorphous materials, glasses, liquids etc. the maxima are broad and relatively weak.
The scattering of x-rays from a crystal, resulting in an interference pattern used to determine the structure of the crystal.
An analytical technique used to identify crystalline solids by measuring the characteristic spaces between layers of atoms or molecules in a crystal. X-ray diffraction can be very useful in the identification of explosive residues.
the scattering of X rays by the atoms of a crystal; the diffraction pattern shows structure of the crystal
X-ray diffraction is a method for studying microscopic crystal form and structure.
a technology that uses x-rays to identify mineral substances.
The scattering of X rays passed through a mineral sample so as to form a pattern peculiar to the given mineral.
is used to determine the structure of crystals. When X-rays are beamed at a crystal, electrons diffract the X-rays, which produces a diffraction pattern. Since X-ray scattering depends upon electron density, the diffraction pattern can be converted into an electron density map. Since electrons more or less surround atoms uniformly, it is possible to fit a molecular structure to this map and determine where atoms are located in the crystal and what atoms are there.
Technique utilized to study atomic structure of crystalline substances by noting the patterns produced by x-rays shot through the crystal.
a technique used to determine the three-dimensional structure of molecules, including macromolecules. A crystal of the substance is illuminated with a beam of x-rays, and the repeating elements of the crystal scatter the x-rays to form a diffraction pattern that gives information on the location of atoms in the molecule (requires resolution of the phase problem).
(1)The diffraction of x-rays by substances having a regular arrangement of atoms. (2)A phenomenon used to identifY substances having such structure.
a technique for studying the crystal structure of a mineral by exposing the crystals to X-rays and observing the pattern made.
