Third Parties and Exploitation,ture determination, it is necessary to determine the precise orientations of the crystal relative to the X-ray beam required to bring each set of lattice planes in turn into the position that fulfils the Bragg condition and causes the scattered radiation to fall on the detector system.

Crystal Lattices,of a crystal, it is thus only necessary to know the simplest repeating “motif” and the lengths and directions of the three vectors which together describe its repetition in space (Fig. 2.1). The motif can be a molecule, as in Fig. 2.1, or the building block of a network structure. Normally, it consi

The Geometry of X-Ray Diffraction, expected when radiation with a wavelength of the order of the lattice spacings interacts with the crystal. In the following sections, the production of the necessary monochromatic X-rays will be described.

Structure Refinement,it which describes the crystal structure reasonably well. There are, however, still substantial errors in these parameters, which arise partly from the approximations of the method of solution, partly from errors in evaluating the maxima in the Fourier synthesis, and partly, of course, from errors i
