Özet
The temperature dependence of the frequency shift and the linewidth is studied using the expressions derived from the anharmonic self-energy. The functional form of the frequency shift is fitted in this study to the experimental data for the R(1) fluorescence line of ruby sample as a function temperature at zero pressure, instead of using empirical nu-P and nu-T relations in the ruby fluorescence method as given in the literature, in particular, for the solid nitrogen. We also demonstrate in this study the temperature dependence of the E(g) librational frequency and its linewidth by fitting the functional forms of both frequency shift and the linewidth to the experimental data for the alpha phase of solid nitrogen.
