Calculation of the C-P-C-V as a function of temperature close to the melting point in benzene
(Taylor & Francis, 2018)
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 ...
Calculation of the thermodynamic quantities from the Raman frequency shifts and the Pippard relations for the alpha, -alpha and alpha ' phases of oxygen
(Elsevier, 2018)
Thermodynamic quantities such as the isothermal compressibility, thermal expansion and the difference in the specific heat are calculated as a function of pressure (T=10 K) for the alpha,-alpha and alpha ' phases of oxygen ...
Molar volume calculated at various pressures and the Pippard relations close to the melting point in benzene
(Taylor & Francis, 2016)
The molar volume of solid and liquid benzene was calculated at various pressures (at constant temperatures), and the Pippard relations were examined close to the melting point in this organic molecule. The molar volume ...
Pressure dependence of the heat capacity near the melting point in benzene
(Elsevier Science, 2017)
The heat capacity C-p is calculated as a function of pressure at constant temperatures of 25, 40 and 51 degrees C for the solid and liquid phases of benzene near the melting point. For this calculation, the observed molar ...
Calculation of the soft-mode frequency for the alpha – beta transition in quartz
(Elsevier, 2016)
The ? – ß structural transition occurs in quartz at TC = 846 K. The frequency of the soft mode associated with the volume increase, decreases with increasing temperature as the transition temperature is approached. In this ...
Calculation of the Raman frequency shifts for the ? phase of solid oxygen
(Elsevier, 2017)
We calculate in this study the Raman frequencies of the two librons and one vibron at various pressures at constant temperatures of 10 K and also at the temperatures of 6 and 18 K by using the volume data from the literature ...
Pressure effect on the cholesteric – smectic A transition in cholestryl myristate
(Taylor & Francis, 2016)
Cholesteryl myristate exhibits tricritical behavior under high pressures close to its cholesteric-smectic A (Ch/SA) transition, as observed experimentally. We study here the thermodynamic properties of this liquid crystal ...
Temperature effect on the structural ferroelectric – paraelectric transition in Li2Ge7O15
(Taylor & Francis, 2016)
Li2Ge7O15 (LGO) undergoes the ferroelectric – paraelectric transition at Tc D283.5K. The crystal structure of LGO is orthorhombic with the four formula units in the unit cell in the paraelectric phase (T < TC) . The ...
Variation of the molar volume with the temperature and the Pippard relations near the melting point in benzene
(Elsevier, 2016)
In this study, we calculate variation of the molar volume with the temperature at constant pressures (70.5, 85.2, 128 and 175.2 MPa) using the experimental data from the literature for the solid and liquid phases of benzene ...
Calculation of the Raman frequencies as a function of temperature in phase I of benzene
(Journal of Indian Chemical Society, 2013)
This study gives our calculation of the Raman frequencies of the lattice modes A (A1g), B (AgB2g) 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. ...
