    It's appreciated that you're explaining Rietveld refinement, but there are some significant issues with the procedure. Beneath the software interface, there are important mathematical models and equations that require careful attention. Your starting model is quite far from the global minimum, and many of the parameters being refined seem out of order. This can lead to incorrect results and potential misinformation for viewers. It might be helpful to review the refinement process for better accuracy.

    How did you measure lattice parameters and atomic position

    What is the maximum allowed value of chi2 value?
    In a refinement carried out, I got Rp= 14.8, Rw= 11.1 Rexp = 2.96, Chi2= 14.1
    Is it okay?

    • @NanoencryptionSKP

      Acceptable value is up to 3 of chie and remaining parameters value should be in the range of 10%

      @@NanoencryptionSKP I earlier show 10% somewhere but quite couldn't understand it. It would be a pleasure if you could make a video on this topic as well which tells us what values of the refinements are accepted. Thanks.

    How to calculate atomic positions of atoms or occupancy without using CIF file??

    I am following the same steps but getting Rp and Rwp more then 40. Can you suggest me something better
