DIRDIF is a computer program system for crystal structure determination by Patterson methods and direct methods applied to difference structure factors. DIRDIF composes of several interrelated computer programs tuned into a program system for solving crystal structures. Major features are the use of Patterson methods, and special direct methods for solving symmetry problems. Powerful procedures are provided for use of your chemical knowledge to solve difficult structures. Ab-initio direct methods and least-squares structure refinement are not included in the DIRDIF package.
