Why ZnO XRD peak intensity 002 only increased or decreased and shift left side after doping other peaks did not changed?

I measured ZnO XRD data. plotted the graph, only peak intensity 002 decreased or increased and shifted left after doping; other peaks did not change.

Why do some of my Raman spectra show no signal at lower Raman shifts?

I'm using a InVia Renishaw Raman microscope system (785nm wavelength, 600l/mm grating density) to acquire Raman images on human brain samples, at 50um resolution. The samples are placed on MgF2...

I have synthesized a composite of ZnO and In2O3 with variations in ZnO content. In Raman , what is the peak observed at 130 cm-1?

Dear all, I have noticed, as the ZnO content increases, the Raman intensity at 100cm-1 also increases. However, there is a peak nearby at 130 cm-1, which I could not find in any paper related to...

This does not look like a spectrum - it looks more like noise, which is supported by the very small variations of the intensity. Concerning a program to analyse FTIR spectra, what exactly would you like such a program to analyze - band assignment, spectrum identification or quantitative analysis?
