FT-Raman spectra of n-propanol and selected partially 2H-labelled analogues

Fourier-transform Raman spectra of CH3CH2CH2OH and some of its selectively deuteriated analogues have been obtained. Comparisons of the Raman spectra of the protiated and partially deuteriated species, in conjunction with polarization data, has enabled improved vibrational assignments to be made for the C–H modes. As a result, confirmation of some literature assignments of stretching and bending modes and revision of other tentative assignments for large biopolymer molecules have been proposed.
