Hi, I am doing the raman analysis of NiOOH. In literature for NiOOH shows the bending vibrations at round about 470 and there is a corresponding stretching vibration at 560. In my raman spectra, I have found a peak at 472 which belongs to the bending vibration of NiOOH but the corresponding peak at 517. What information does this provides ? Please give valuable suggestions. I am also attaching the raman spectra.

Note: I have pasted the catalyst ink on carbon paper thats why there are some peaks which belongs to the carbon.
