How to find the index lattice of single crystalline through SAED pattern?

14 May 2025 0 6K Report

I am finding index lattice of iridium oxide through SAED image as attached image. I learned how to calculate d-spacing on youtube, and followed to find index lattice.

D-spacing found here is around 0.75 A, referencing to some relative Iridium oxide structures, it does not fit any.

I would like to ask for help from any experienced researchers.

Thanks in advance.
