We demonstrate the use of a light-emitting diode (LED) based experimental setup for collecting polarization-resolved Raman spectra with good spectral resolution. The combination of a commercial red LED (630 nm), a 1-nm bandwidth laser-line filter, and a polarizing prism is used as a light source. Polarization-resolved spectra in dimethyl sulfoxide are recorded and compared with the corresponding laser-Raman spectra. The LED-excited spectra exhibit a resolution slightly lower than those in the laser case but still close to the resolution of the spectrometer. All relevant spectral features of dimethyl sulfoxide including the symmetric and antisymmetric stretching modes of the CSC moiety are resolved with the experimental setup providing a spectral resolution of approximately 20 cm−1.
