Hi fellow CCLers, I am looking for any information (source, cost, books etc.) on the codes CRYSTAL or CRYSTAL 92 and EMBED devised by Pisani, Dovesi and coworkers. There doesn't appear to anything on these programs on the www unless of course I've been looking in the wrong place. Any information on this topic would certainly be appreciated. Thanks in advance, Darren Darren Simpson University of South Australia The Levels, SA 5095 Australia
