Özet

The pressure dependence of the Raman frequencies of the internal modes is analyzed (T = 300 K) for the phases i and theta of solid nitrogen using the experimental data from the literature. Through the mode Gruneisen parameter, the isothermal compressibility kappa(T), thermal expansion alpha(p) and the specific heat C-p - C-v are calculated as a function of pressure using the Raman data in these phases.
