DEBVIN - a program for Rietveld refinement with generalized coordinates subjected to geometrical restraints

DEBVIN is a program that combines the Rietveld approach with the use of generalized coordinates. It is a particularly useful tool when, as in polymer crystallography, structures are rather complex and diffraction patterns highly overlapped and confined to low diffraction angles. Refinement of crystallite dimensions is also a qualifying feature of this program.
