distributions of atoms in real crystal structures. Basic equations describing diffraction are mentioned. Diffraction techniques that are the source of data used for structure determination are explained by means of the Ewald construction. C.

Crystallography in Earth Sciences:
Structural crystallography - basic conceptions:
symmetry restrictions due to the lattice periodicity, point groups, crystal systems, Laue classes, Bravais lattices, Miller and diffraction index, interplanar spacing
Space groups:
asymmetric unit, multiplicity, special and general positions
Theory of diffraction:
Laue equations, systematic absences
The diffraction of X-rays by crystals:
(Laue method, rotation method, precession camera, single-crystal diffractometer) data collection techniques for polycrystalline material, interpretation of powder patterns, Rietveld method, solution and refinement of crystal structures, neutron diffraction, electron diffraction |
