Dear Dr. Patrick , thank you very much for your content, i would like to ask you if you could make some content that treats the case when we transform from one space group (e.g. Fmmm ) to another space group that is non-conventional (e.g., F 2/m) and how should we approach such case ? also how how can we identify (when we have it) the unique axis from the Powder XRD pattern? Thank you.
