This is the page from which demo and commercial versions of several crystallographic software packages can be downloaded or purchased. The software products available from this site are: ATOMS (a program for drawing all types of atomic structures, including crystals, polymers and molecules); SHAPE (a program for drawing the external morphology (faces) of crystals and quasi-crystals, and also for drawing sections of crystals); VIBRATZ (a program for doing a complete normal-coordinate calculation on any molecule or crystal, using traditional valence force constants and/or Urey-Bradley force constants); CRYSCON (a shareware program for general crystallographic conversion). Free demo versions of each product are available; this software is available for Windows, Macintosh, and Linux platforms.
