Dear Rietveld users,
I am currently looking for a reference for the strategy of collecting
XRD data on lab diffractometer.
With the help of new diffractometers we can collect the data in the VCT
(Variable Counting Time).
This last method has been studied by IC Madsen and RJ Hill (1994).
No
Dear Francois,
I know this one:
Routine ab initio structure determination of chlorothiazide by X-ray powder
diffraction using optimised data collection and analysis strategies

I don't think that varying the step size is particularly useful. The
FWHM usually increases with angle for sure, but so does the number of
peaks per degree, so you want the finest step to stand a chance of
seeing any subtleties in the profile due to overlapping peaks. I think
it's more useful t
