DEBUSSY DebUsSy stands for Debye User System and consists of a suite of programs implementing a fast approach to the Debye Scattering Equation (DSE) Analysis for powder diffraction data from nanocrystalline and/or non-ordered materials.
Debussy uses the previously created database(s) and carries out a fast calculation of the diffraction profile of each cluster that contributes to the total pattern, according to a suitable and adjustable size-distribution function. The analysis can be performed on single- or multiple-phase specimens, trying to fit one or more experimental data sets collected with Synchrotron or laboratory X-ray, neutron and electron beams. For all radiation types, the scattering amplitudes/factors of atomic species are encoded into the program. Different options are also available to deal with lattice expansions or contractions variable with the crystal size. Both Chebyshev polynomials and experimentally collected data can be used to manage the background component.
DEBVIN Rietveld refinment with generalized coordinates subjected to geometrical constraints.
DebyeFit DebyeFit is a tool to calculate the Debye or Einstein characteristic temperature of thermal vibrations in crystals from the equivalent atomic displacement parameters (ADPs) of any atom at user’s option that have been obtained at several temperatures. The ADP values are separated into static and dynamic components to get a best fit to the model Debye / Einstein curve. Calculations are based on the Debye, Einstein or mixed model at user’s option. An additional term is first added to the equations to account a possible static disorder. Nonlinear least-square technique is used to refine parameters of the model curve for the set of ADPs observed in the various-temperature structural study. The program provides a good fit up to 0.5 – 2% between the theoretical and observed ADP values. It is quite possible that the best dependence is first achieved within the framework of the Debye or Einstein models between ADPs obtained at different temperatures owing to a simple modification of the formalism

dSNAP to help users automatically classify and visualise the results of database searches using the Cambridge Structural Database.
DSR - Disordered Structure Refinement Its main purpose is the transfer of molecular fragments to a user-defined location in the target structure. Writing a special DSR command into the SHELXL .res file of the target structure instructs DSR on where to place and how to orient a molecular fragment from the fragment database in the unit cell. In addition, it is possible to define the occupancy, residue or part number of the inserted fragment. The fragment can be inverted, e.g. to fit the second conformer of twisted tetrahydrofuran. If desired, automatically calculated distance restraints for all bonds in the molecular fragment can replace the restraints obtained from the database. Additional options in the system command line allow the import and export of molecular fragments to and from the database, and listing of and searching for database content.
