WebGeneral approach to solution • Step 1: Initial phasing – Come up with an approximate solution for the structure (and thus an approximate set of phases) • Step 2: Phase refinement – Then consider perturbations to the structure – Search for perturbations that improve the fit to the experimental data (the diffraction pattern) 22 WebAbstract. The intensities of a sufficient number of X-ray diffraction maxima determine the structure of a crystal, that is, the positions of the atoms in the unit cell of the crystal. The available intensities usually exceed the number of parameters needed to describe the structure. From these intensities a set of numbers E H can be derived ...
