The phonons of MnWO4 single crystals are studied by Raman scattering spectroscopy. The 18 zone-center vibration modes are assigned and their temperature dependence of the Raman wavenumbers and the FWHM of the modes are studied. The evidence of new transition temperatures at 50 and 180 K of MnWO4 is found.
