hello, can you help me determine the nature of this intenses peaks . the graphical representation is of x-ray diffraction. I want to know that it means the two peaks at 2 theta 35 and 44.
It is not clear what kind of spectra is this, and what discussion you need to have over the 'nature' of the peaks'. Could you please update the question with more details.
If you have the theoretical information of the Bragg angles for this sample, then you can related these 2-theta values with the respective reflecting planes for the sample. These peaks correspond to the reflections of the incident X rays from the planes in the sample. Different planes of atoms would cause the X-rays to reflect at different angles.
