I'm fairly new to Rietveld techniques, so I apologise if I'm making a
glaringly obvious mistake here.
I'm currently attempting to use a Rietveld program (KOALARIET) to
conduct quantitative analyses on dusts collected from the exhaust
gases of various industrial processing plants. Anhydrite (CaSO4) is
frequently present. However, once the refinement has been run, there
is clearly an anhydrite peak which has not been fitted (at d =
2.849A) and on further investigation this reflection has not been
generated during the profile calculation. The peak is also missing
when using profile calculation programs such as POWDERCELL.
However, it is present in the ICDD record. What am I doing
wrong?
Thanks in advance for any advice that can be offered,
