In this technique, the Patterson function can be used to solve the phase problem. Samples undergoingthis technique often have selenium incorporated in order to take advantage of multi-wavelength anomalousdispersion. The raw data from this process is compared to the model in order to find the R-factor. Thistechnique was used by John Kendrew on myoglobin derived from sperm whales, and in this technique, apure, precipitated macromolecule is mounted on a goniometer and rotated while being bombarded
