The vibrational spectra of gaseous and liquid 2-propanol in the C–H stretching region were investigated by polarized photoacoustic Raman spectroscopy and conventional Raman spectroscopy. With the help of isotope substitution and depolarization ratio measurement as well as quantum chemistry calculation, the overlapping spectral features between the CH and CH3 group were identified, and new assignments were presented.
