SIR 97 is the integration of two programs, SIR 92 and CAOS , the first devoted to the solution of crystal structures by direct methods, the second to refinement via least-square...
SIR 88 is an integrated package of computer programs for the solution of crystal structures. The package is based on the estimation of one- and two-phase structure seminvariants...
A theory is described which, for any universal structure invariant or structure seminvariant, Φ, is able to arrange the set of reflexions in shells, each shell a subset of the s...
A probabilistic approach is described which is able to estimate triplet cosine invariants via their second representation. The experimental tests on structures of different comp...
The fundamental ideas of representation given in a preceding paper [Giacovazzo (1977). Acta Cryst. A33, 933-944] are generalized further. Some algebraic properties of structure ...
In some recent papers [Giacovazzo, Burla & Cascarano (1992). Acta Cryst. A48, 901–906; Burla, Cascarano & Giacovazzo (1992). Acta Cryst. A48, 906–912; Cascarano, Giacovazzo, Mol...
Abstract The combination of the random approach with the representations method proved of large usefulness. Very difficult structures can be routinary solved via the package SIR...
Electron-density maps are calculated by Fourier syntheses with coefficients based on structure factors. Diffraction experiments provide intensities up to a limited resolution; a...
