The temperature dependences of the spontaneous polarization and the dielectric constant (susceptibility) are calculated using themean fieldmodel for the ferroelectric N(CH3)(4)HSO4. Expressions derived from the mean fieldmodel for the spontaneous polarization and the inverse susceptibility are fitted to the experimental data from the literature. The fitting parameters in the expansion of the free energy in terms of the spontaneous polarization are determined within the temperature intervals in the ferroelectric and paraelectric phases of N(CH3)(4)HSO4. Our results show that the temperature dependences of the spontaneous polarization and the dielectric constant as predicted from our mean field model, describe adequately the observed behavior of N(CH3)(4)HSO4 in the ferroelectric and paraelectric phases.

Analysis of the Raman Frequency Shifts for the Lattice Modes and Vibrons Related to the Thermodynamic Quantities in the eta Phase of Solid Nitrogen
Yurtseven, Hasan Hamit (Walter de Gruyter GmbH, 2013-08-01)
The thermodynamic quantities of the isothermal compressibility, thermal expansion and the specific heat are calculated here as a function of pressure by using the observed Raman frequencies of the lattice modes and vibrons in the. phase of solid nitrogen. The Pippard relations and their spectroscopic modifications are constructed, and the slope dP/dT is deduced from the Raman frequency shifts in this phase of N-2. It is shown that the thermodynamic quantities can be predicted from the Raman frequency shifts...
Calculation of the Specific Heat Close to Phase Transition in S-triazine
KURT, MUSTAFA; Yurtseven, Hasan Hamit (Walter de Gruyter GmbH, 2009-01-01)
The specific heat C-V as a function of temperature has been calculated using the quasi-harmonic and mean field approximation for s-triazine close to the transition temperature (T-C=198 K). Using the parameters for the shear strain angle (order parameter) fitted to the observed Raman frequencies of the four bands, the specific heat C-V is calculated from the free energy of s-triazine.
Calculation of molar volume as a function of temperature close to the melting point in benzene
Yurtseven, Hasan Hamit (Walter de Gruyter GmbH, 2007-01-01)
We study here the temperature dependence of the molar volume for constant pressures in benzene close to the melting point. By analyzing the experimental data for the thermal expansivity at various pressures in benzene, we calculate the molar volumes as functions of temperature in this system. Our calculations show that discontinuities in the molar volume decrease as the melting temperatures increase along the melting line when the constant pressures vary from 70.5 MPa to 175.2 MPa, as also observed experime...
Calculation of the Raman Linewidths of Lattice Modes Close to the alpha-beta Transition in Quartz
Lider, Mustafa Cem; Yurtseven, Hasan Hamit (Walter de Gruyter GmbH, 2012-12-01)
The Raman frequencies of the lattice modes (147 cm(-1) and 207 cm(-1)) are analyzed for the alpha-beta transition in quartz according to a power-law formula with the critical exponent by using the experimental data. The temperature dependence of the Raman frequency is associated with the order parameter (polarization P) for this transition in the quartz crystal.
Calculation of the C-P-C-V as a function of temperature close to the melting point in benzene
Tari, O.; Yurtseven, Hasan Hamit (Informa UK Limited, 2018-01-01)
The temperature dependence of the C-P - C-V is calculated at constant pressures using the observed volume data from the literature for solid and liquid benzene near the melting point. Our calculated values are compared with some earlier treatments and we find that they disagree at constant pressures for the solid benzene, whereas for the liquid benzene agreement is reasonable in terms of the order of magnitude between our calculated C-P - C-V and those predicted from the Peng-Robinson equation of state. Our...
