    Thank you for the video, I was looking for mixed phase refinement process. But, I have one question, is it possible for both U & V (instrument parameter) be negative?

      Yes, I have an instrument file from the synchrotron center showing a negative value for both U and V.

    Handy video, i have subscribed to your channel.. 👍... Could u ple make a step-by-step video of the refinement of dual phases.. including plotting in Origin also,, the most problem is facing the plotting in origin

      Thank you for suggestion and hope that it worked for you. The refinement I have shown in this video is for 2 phase system. I will upload another video on plotting using origin software.

      Thank you very much sir.. Intensely waiting for... Please do ASAP.. Because i have waisted more then 2 weeks.. Luckily, i have finally found your videos.. Its very helpful for me... But facing problem how to plote in origin that refined data

    Sir how to get the ratio of two phases present in the total xrd spectrum?

      The ratio also called as weight fraction can found in the final exported report.

    Sir, How can we do the Rietveld refinement of a sample whose cif file is not in any database?

      If it’s not in the data base and also in the literature then you might be dealing with an unknown compound. In that case you may need to discuss with an expert or a theorists.

      Si tu compuesto es multifase, puedes usar los compuestos simples y hacer cambios en la ocupación.

    How do you perform XRD Rietveld refinement without an instrument file? ruclips.net/video/ZD_vvH7MvtM/видео.html
