Nettet24. aug. 2024 · Why narrow peak has greater intensity in XRD? The intensity and width of the peaks depend on the number of groups present in the structure. Why does XRD peak intensity decrease? Stress in the sample leads to broadening of peaks, and it’s an experimental issue. Peak intensity is decreased when peak broadeneing occurs. Nettet13. apr. 2024 · All the CIF information is sent to the intensity module, which uses the crystal information to obtain the intensity of the non-null reflections. For this purpose, the program generates all the atomic positions from the .cif file's atomic positions and symmetry operations.
