The temperature and pressure dependences of the Raman frequencies of the lattice modes (E-g and B-1g modes) and of an internal mode (2331 cm(-1)) are predicted using the observed molar volume data from the literature in the gamma-phase of solid N-2. This calculation is carried out by means of the mode Gruneisen parameter of each Raman mode in the gamma-phase of solid nitrogen. Our results show that the predicted Raman frequencies of the E-g mode increase as the pressure increases. The Raman frequencies of the other lattice mode (B-1g) and the internal mode (2331 cm(-1)) decrease with increasing pressure due to their negative Gruneisen parameters in the gamma-phase of solid N-2. The temperature effect on the Raman frequencies is negligibly small.

Temperature and pressure dependence of the Raman frequency shifts in anthracene Ozdemir, H.; Yurtseven, Hasan Hamit (2016-08-01) In this study, the Raman frequency shifts of phonons and vibrons of crystalline anthracene as functions of temperature (at zero pressure) and pressure (at ambient temperature) have-been calculated using the experimental volume data from the literature. This calculation is performed for six phonons and nine vibrons through the mode Gruneisen parameters which have been determined from the Raman frequency and volume data at various pressures. Our predicted Raman frequencies of the phonon modes decrease with in...
Temperature and Pressure Dependence of the Linewidth for an Internal Mode in the Solid Phases of Benzene Yurtseven, Hasan Hamit (2013-10-01) The pressure dependence of the Raman linewidths for the upsilon(1) breathing mode is analyzed using the experimental data from the literature for the solid phases (I, II, III and III') in benzene. Increase (I, III and III') and decrease (II) in the Raman linewidths are described by a power-law analysis with the critical exponent beta. The beta values we find, which characterize the phase transition are in favour of the first order among those phases considered in benzene. The temperature and pressure depend...
Pressure dependence of the Raman frequency calculated from the volume data close to the ferroelectric-paraelectric transition in PbTiO3 Yurtseven, Hasan Hamit (2017-01-01) We calculate the pressure dependence of the Raman frequencies of some Raman modes by using the observed volume data through the mode Gruneisen parameters for the ferroelectri-paraelectric transition in PbTiO3. The mode Gruneisen parameters which we have determined using the observed Raman frequencies for the soft modes, increase considerably with increasing pressure toward the transition pressure (PC similar to 11 GPa) from the tetragonal (ferroelectric) to the cubic (paraelectric) phase in PbTiO3. Variatio...
Temperature dependence of the Raman frequencies and bandwidths close to phase transitions in ammonium halides Yurtseven, Hasan Hamit (2001-09-01) In this study, we give the temperature dependence of our observed frequencies and bandwidths for the Raman optical modes in the ammonium halides close to the phase transitions of the first order (NH4 Br), tricritical (NH4Cl) and second order (NH4Cl). Using the predictions of an [sing pseudospin-phonon coupled model, which considers interactions between two spin and two phonons, our observed Raman data have been interpreted qualitatively. Our results show that an Ising model considered here can explain the o...
Calculation of the Raman and IR frequencies from the volume data at high pressures in N-2 AKAY, ÖZGE; Yurtseven, Hasan Hamit (2018-01-01) Raman and IR frequencies of N-2 in the molecular state are calculated as a function of pressure up to 160 GPa by using the volume data from the literature through the mode Gruneisen parameter. By determining the Gruneisen parameters for the lattice modes and vibrons which decrease mostly with increasing pressure from the observed frequency (Raman, IR) and volume data, the Raman and IR frequencies of those modes are calculated at various pressure at room and low temperatures. We find that the Raman and IR fr...
