Özet

We study here the Raman frequencies of the lattice modes (gamma and beta phases) and of an internal mode (gamma phase) as a function of temperature in solid nitrogen. The frequency shift, derived from the anharmonic self energy, is fitted to the experimental data for the Raman frequencies of the modes considered here in the gamma and beta phases of solid nitrogen.
