By hiding the reciprocal lattice and the Ewald sphere during this exercise and just looking at the diffraction patterns, this exercise closely mimics the determination of space groups in real structural analyses. Use of XRayView on Research Projects XRayView is also useful for research purposes, allowing 'simulation' of many real diffraction effects. In my laboratory, we have found it useful for guiding the reorientation of crystals from being aligned along one zone to another, and for verifying reciprocal lattice symmetry effects in real 'unknowns'. How To Obtain XRayView XRayView is available free to universities and other educational institutions, and by special arrangement to other organizations. Any proceeds are used for further development of educational software for teaching purposes, including improvements to XRayView.
