Raman and infrared spectra of polycrystalline samples of N2O4 at low temperatures have been recorded. The number and activities of the fundamentals are compared with the predictions of group theory, based on the known molecular and crystal geometries. Several additional peaks are attributed to Fermi resonances of combinations with fundamentals. A new low frequency internal mode and five lattice modes have been observed.
