I'm wondering if anybody has experience using Fullprof to refine Argonne TOF
powder diffraction data which has not been treated to account for the shape
of the incident spectrum i.e. not had incident spectrum stripped from raw
data.

I have problems to fit
zero point and specimen displacement together using Fullprof.
What can I do to resolve this problem?.

As Davor mentioned, surface layers are an additional "handicap"
in modelling the line profiles and suggest you take a look at
his paperit's a very good one.
I would like to remind you one more thing...the peak asymmetry

I second all of Koray's remarks but add a comment on peak asymmetry of 00L
reflections. This asymmetry (a low-angle peak shoulder) is likely to
originate from a distinct surface layer probably common to all
ferroelectrics, and especially to BaTiO3 (Kanzig has reported it first back
in 1955). It ca

We too. However the French CNRS attitude is to do the contrary
of our UK colleagues. In 1997, all CNRS labs had free access to
the Cambridge Structural Databas

Even the demo database of ICSD-for-WWW contains some useful references

Dear Ritvelders,
I perform neutron diffraction study of some orthoferrites. Does anybody
know any references to inorganic crystal databases, avaliable by WWW?
Thanks in advance,
