Raman Study of Solid Nitrogen in the β Phase and Close to the Melting Line

Abstract This study gives the Raman frequencies calculated as functions of temperature and pressure for the lattice modes in the solid β phase and close to the melting line (β-fluid transition). The experimental volume data from the literature is used to calculate the Raman frequencies for the molecular nitrogen system. Some observed Raman frequencies are also used as the initial data to perform our calculations given here. It is shown that our values predict the observed Raman frequencies of the lattice modes studied in the β phase and also on the solid β-fluid melting curve. This initiates the applicability of the method given here to calculate the frequency from the volume data in various phases of molecular solids such as solid nitrogen.
