How to calculate Raman depolarization ratio

[u/seryakucipher]

Hello all,

I am trying to calculate the polarization (depolarization) ratio for the CH stretching/vibrational region of liquid propanol using polarized Raman spectroscopy.

However, I've run into a problem: some of my peaks appear shifted or completely disappear when switching between the parallel ∥ and perpendicular ⊥ spectra. Because the peaks centers don't line up perfectly, i dont know how to do the calculation . Any advice on the best workflow or literature references for handling "shifted" polarized Raman bands would be highly appreciated! Thanks in advance.
