In this study we calculate the Brillouin frequencies for the L-mode [010], [001] and [100] in the ferroelectric phase of NaNO2 (T-C = 163 C) by means of gamma -Gruneisen relations using the thermal expansivity data from the literature. The predicted frequencies are in good agreement with the observed Brillouin frequencies for the modes studied in the ferroelectric phase of NaNO2. This indicates that our method presented here predicts the observed behavior of NaNO2 in the ferroelectric phase.

Application of the spectroscopic modifications of Pippard relations to NaNO2 in the ferroelectric phase Yurtseven, Hasan Hamit (2001-01-01) This study examines a linear variation of the specific heat C-P with the frequency shifts 1/nu(partial derivative nu/partial derivativeT) for the Brillouin frequencies of the L-mode [010], [001] and [100] in the ferroelectric phase of NaNO2 according to our spectroscopically modified Pippard relation. We obtain this linear relationship for those modes studied and calculate dT(C)/dP in the ferroelectric phase of NaNO2. Our calculated values of dT(C)/dP for the [001] and [100] modes are in good agreement with...
Spectroscopic modifications of the Pippard relations for NaNO2 in the sinusoidal antiferroelectric phase Tari, O; Yurtseven, Hasan Hamit (2002-06-01) We establish in this study a linear variation of the specific heat C-p with the frequency shifts (1/nu)(partial derivativenu/partial derivativeT) in the sinusoidal antiferroelectric phase of NaNO2, according to the first Pippard relation which we have modified spectroscopically. For this linear relationship we use the Brillouin frequencies of acoustic phonon modes for the q[010], q[001] and q[100] modes of NaNO2 in the sinusoidal antiferroelectric phase. We then calculate dT/dP values due to those modes stu...
Calculation of the Brillouin frequencies close to phase transitions in NaNO2 Yurtseven, Hasan Hamit (2002-01-01) We calculate here the Brillouin frequencies of the L-mode [010], [001] and [100] of NaNO2 for the phase transitions from the paraelectric phase to the sinusoidal anti-ferroelectric phase near the Neel temperature (T-N = 437.7 K) and to the ferroelectric phase near the critical temperature (T-c = 436.3 K) in this crystalline system. For calculating the frequencies, we use the thermal expansivity data for the phase regions considered, under the assumption that the mode Gruneisen parameter determined for each ...
Calculation of the Raman frequencies as a function of temperature in phase I of benzene Tari, O.; Yurtseven, Hasan Hamit (2013-06-01) This study gives our calculation of the Raman frequencies of the lattice modes A (A(1g)), B (A(g)B(2g)) and C (B1gB3g) as a function of temperature at constant pressures of 0, 1.4 and 3.05 GPa for the solid phase I of benzene. The Raman frequencies of those lattice modes are calculated using the volume data from the literature through the mode Gruneisen parameters for the solid phase I of this molecular crystal. It is shown here that the Raman frequencies of the lattice modes studied decrease with increasin...
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...
