Lithium, Iron, and Phosphate precursors were used for the synthesis of LiFePO4 by Hydro-thermal synthesis route. The XRD data of the sample is attached herewith which is taken at 14.99635eV corresponding wavelength 0.8267591277(A0) . It is mentioned that the valid range for 2theta is 5 to 40.2. and Synchrotron x-ray source was a continuous x-ray source, one can chose any wavelength within a specified range.

Last time when i analyse the xrd data of similar like samples, I directly pasted on origin and "x'pert High Score" Software where I get confirmation of structure (Using default 1.54angstrom wavelength) formed successfully.

But this time as the wavelength 0.8267591277(A0) is used (samples are approximately similler) I am getting peaks at different values of 2theta where i am not able to confirm the structure.

I request anyone to help regarding how to find the structural phase of sample when different wavelength is used.

Also here my question is: As per theory of diffraction if we change wavelength diffraction pattern gets changed too (as in case of single slit experiment one with red colour wavelength used and another with green)

So when we change wavelength of x-ray source in Synchrotron will it change diffraction pattern (Will peaks be at different values of 2theta.)
