why on ftir graph there are several peaks for the same compound but at different wavelengths? what causes the different modes of vibration for the same compound (PO4), what causes the v1 ,v3,v4 for PO4... help me please:frown:

thanks for responding,,, I'll give it a try

hello everyone...:smile:

I have a sample that was analyzed with x-ray diffraction, the graph had several peaks at different 2θ degrees, how to know if this sample has fluorapatite? I need the answer ASAP please..
