Space Group Explorer

This program gives you immediate access to much of the information which is available in the International Tables for Electron Crystallography, on-line in your own PC.

The Space Group Explorer gives equivalent positions in real and reciprocal space, the symmetry of the diffraction pattern, and information about systematic absences and enhancements. It also gives phase relationships of the Fourier terms, and seminvariant vectors.

The program is based on the program sginfo from Ralf W. Grosse-Kunstleve, Laboratory of Crystallography, ETH Zürich, Switzerland. Ralf's E-mail address is, and he has a site at with full information about sginfo.

Space Group Explorer is freeware, and can be downloaded by clicking here. (78.5KB, zipped file).
