RE: Rietveld condamnation considered as established by some more people

My review of Mittemeijer’s book seems to have excited interest in the history of the “Rietveld” method. I, myself, recall using Alan’s modified program (incorporating anisotropic displacement parameters, a welcome addition) in the early days and I saw that many Rietveld programs also contained

symmetry in the other? Can you be sure that you get the same answer? I suspect it makes little difference to the actual outcome, but I cannot prove that. Mike Glazer From: Robert Gould Sent: 30 December 2022 14:31 To: Mike Glazer Cc: Radovan Cerny ; Matthew Rowles ; RIETVELD_L Distribution List

any case, all observed symmetry in crystals results from averaging over space and time. Mike Glazer From: Radovan Cerny Sent: 30 December 2022 12:44 To: Matthew Rowles Cc: Mike Glazer ; RIETVELD_L Distribution List Subject: RE: "2d materials don't exist" editorial?? Uff, I do n

Radovan Not quite. Graphene is a 3d material but has periodicity in 2d making its symmetry given by one of the 80 subperiodic layer groups. Mike Glazer Get Outlook for Android<https://aka.ms/AAb9ysg> From: rietveld_l-requ...@ill.fr on behalf of Radovan

This all sounds like Reverse MonteCarlo (RMC) modelling. We have used this with PDF analysis. Mike Glazer ++ Please do NOT attach files to the whole list Send commands to eg: HELP as the subject with no body text The Rietveld_L list
