I am distributing the following message to the Rietveld list on behalf of
the Workshop organisers:
Dear Colleagues,
We would like to remind you of our upcoming workshop “New Trends in
Magnetic Structure Determination”, to be held in Grenoble, at the Institute
Laue-Langevin, from 12 to 16
Dear yashwanth padarthi
I do not have the powder diffraction file at hand at the moment.
In a CIF file for your structural compounds all atoms are listed that are in the
asymmetric unit of the structure. The symmetry operations of the space group
will expand these to the full content.
Take the
Dear sir,
Can i know what is the significance of U,V,W separately?what do they
signify *if i have a plot of two theta Vs intensity how can one show what
U,V,W is separately*? i have researched a lot but they are no particular
significant meaning. i only know they depend on the instrument
Cagliotti shows how U,V,W are related to the collimation alpha1, alpha2,
alpha3 and mosaic spread beta of the monochromator crystal for a classical
neutron powder diffractometer; a further discussion is given here
As Alan states, the U, V, and W terms are often employed in situations where
their physical meaning is minimal:

Dear MAUD users,
I would like to know where can I find the U, V, W parameters to refine
on MAUD software.
Thank you very much.
