In practice, people use whatever is available in the refinement programs (sometimes blindly :-) The authors of those programs have already spent considerable effort in writing manuals, and users should be encouraged to read those as a first step :-) The Rietveld mailing list http://www.mail-archive.com/rietveld_l@ill.fr/ is also a useful source of different opinions on techniques. Often wikis are well done, but sometimes represent wacky opinions of a few individuals. Google itself is often a better source of information. And of course most refereed papers are now available on the WWW, and can readily be found with google. Alan BTW Mike Glazer is right that people should be more concerned with physical-chemical tests of their structure, rather than trying to get the lowest possible R-factor by refining more parameters. ______________________________________________ Dr Alan Hewat, NeutronOptics, Grenoble, FRANCE <alan.he...@neutronoptics.com> +33.476.98.41.68 http://www.NeutronOptics.com/hewat ______________________________________________
