How to Determine the Unit Cell Type From the XRD Data?

[Dario56]

Hey guys,

I got an XRD data for my sample and want to determine its density. This requires finding lattice parameters. However, I'm not certain about the crystallographic system of my sample. How can I determine the type of the unit cell my sample has from XRD data (I can use GSAS II if needed)? Do you know a good source where I can study this?

Textbook I have (X-Ray Diffraction from Warren) doesn't explain it very clearly to me and Google search didn't give the good sources.

Way out of my field but a quick Google search found:
https://www.researchgate.net/post/how_can_we_determine_the_lattice_parameter_using_XRD

(above found with:
https://www.google.com/search?q=calculating+lattice+parameters+from+xrd+data

If that doesn't work well, try the same search string at: https://scholar.google.com, instead of www.google.com)

Cheers,
Tom
