Picking up on Bob’s point. As an author of a commercial program I don’t see the world coming to an end. In this melodramatic discussion the idea of encouraging young scientists to write the type of software that the community is demanding is fraught with difficulty. Unless of course a scientist c

I would only add that much of the software development is done as a "hobby" by many us, i.e. with only grudging institutional support. Bob -Original Message- From: L. Cranswick [mailto:[EMAIL PROTECTED] Sent: Fri 3/19/2004 3:44 PM To: [EMAIL PROTECTED] [hope this is not a resend - Ema

I don't know that machine but isn't it so that nowadys structures can be solved with "home lab instruments". The name of the instrument doesn't give enough information to jugde whether solution is true or not. The usual advice about checking the interatomic distances is valid for any structure

Hola de nuevo, si el diffractometro no tiene una configuración especial tipo detector banana-1D (que a veces distorsiona los picos), o monocromador de entrada (que si esta mal colocado puede dar un pelin de Kalpha2), no veo porque no se podria hacer Rietveld. bueno de poca auyda sera todo esto..

Dear all, How reliable is a structure refinement (including atomic positions and temperature factors) from an X-ray diffraction pattern recorded on a Rigaku D/max X-ray powder diffractometer? Thank you very much! ana Dr. Ana Isabel Becerro Departamento Química Inorgánica Instituto de Ciencia
