Lattice modes of solid nitrogen were studied by Raman spectroscopy at room temperature to 104 GPa using the diamond anvil technique. Changes in the lattice mode spectral features correlate with those observed in the vibronic spectra suggesting symmetry changes of the crystal lattice. The changes in the
spectral features mainly appear as branchings of existing modes supporting the view of a close structural relationship among these high pressure phases.
