Raman frequencies of six lattice modes are calculated as a function of pressure using the volume data from the literature by means of the isothermal mode Gruneisen parameter (gamma(T)) for the solid phase I of benzene. We find that by determining the yr decreasing, the Raman frequencies calculated for the phonon modes increase with increasing pressure in this solid phase of benzene, which agree with the observed Raman data. We also predict the T-P phase diagram between the solid phases of I and I' by using the calculated Raman frequencies of the six lattice modes of benzene. Our calculated T-P diagram does not match properly with the observed data, which needs to be reconsidered by analyzing a number of measurements for the I - I' transition in benzene.

Raman frequency shifts calculated from the volume data in naphthalene Ozdemir, H.; Yurtseven, Hasan Hamit (2015-06-15) The Raman frequencies for modes of symmetry Ag and Bg are calculated as functions of temperature (at atmospheric pressure) and pressure (at room temperature) using the observed volume data from the literature through the mode Gruneisen parameters in naphthalene. By determining the temperature and pressure dependence of the isobaric (gamma(P)) and isothermal (gamma(T)) mode Gruneisen parameters, respectively, the Raman frequencies of the modes which were calculated, are in good agreement with the observed fr...
Raman Frequencies Calculated at Various Pressures in Phase I of Benzene Tari, Ozlem; Yurtseven, Hasan Hamit (2013-04-01) We calculate in this study the pressure dependence of the frequencies for the Raman modes of A (A(g)), B (A(g), B-2g) and C (B-1g, B-3g) at constant temperatures of 274 and 294K (room temperature) for the solid phase I of benzene. Using the mode Gruneisen parameter of each lattice mode, which correlates the pressure dependence of the crystal volume and the frequency, the Raman frequencies of those modes are computed for phase I of benzene. Our results show that the Raman frequencies of the three lattice mod...
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...
Raman bandwidths calculated for the librational ( a -phase) and internal (8, d loc and d phases) modes in solid N 2 using pseudospin-phonon coupling (PS) and energy-fluctuation (EF) models Yurtseven, Hasan Hamit (Elsevier BV, 2020-10-01) This study gives the calculation of the Raman bandwidths using the models of the pseudospin-phonon coupling (PS) and energy fluctuation (EF) where the Raman frequency calculated from the molecular field theory, is considered as the order parameter close to the phase transitions in nitrogen. In particular, we study the temperature dependence of the Raman bandwidths and frequency shifts of the Eg librational mode (zero pressure) and the internal modes of and (at various pressures) for the solid nitrogen by ...
