Crystal structure factors and symmetry

Show Summary Details


The structure factors, with their hkl indices, amplitudes and phases are dealt with in great detail. With figures, text and formulas the physical meaning of amplitudes and phases is explained. Rotation matrices and translation vectors are described mathematically as well as in figures. Plane group and space group determination from HRTEM images and ED patterns are explained. The relation between electrostatic potential and structure factors (Fourier terms, i.e. reflections) is described with formulas, structure model, EM image, ED pattern and a table of numerical values of amplitudes and phases for the structure Zr2Se.

Keywords: Structure factors; symmetry; amplitudes; phases; Fourier synthesis; rotation matrices; translation vectors; equivalent positions; phase restrictions; systematic absences; space-group determination
