This study gives an evidence for the validity of our spectroscopic modification of the Pippard relation as apphed to ammonia solid I close to the melting point. We use our calculated frequencies for the rotatory lattice (librational) mode in ammonia solid I for the pressures of 0, 1.93 and 3.07 kbars. We obtain that the specific heat C-p varies linearly with the frequency shifts 1/v(delta v/delta T)(p) for this Raman mode at those pressures studied in this crystalline system. Our values of the slope dP(m)/dT that we deduced from the linear plots, are not in satisfactory agreement with the experimental values in ammonia solid I near the melting point.

Analysis of The Molar Volume as A Function of Pressure Close to The Melting Point in Ammonia Solid III Yurtseven, Hasan Hamit (2009-06-01) This study gives the calculation of the molar volume as a function of pressure for constant temperatures in ammonia solid III near the melting point. Using the value of the critical exponent gamma extracted from the experimental,data for the isothermal compressibility kappa(T). The molar volume calculated here decreases as the pressure increases on approach to the melting point. This critical behaviour can describe the observed behaviour of the molar volume near the melting point, as obtained experimentally...
Critical behaviour of the thermodynamic quantities near the melting point in the solid phase of hexadecane Yurtseven, Hasan Hamit (2008-01-01) We study here critical behaviour of the thermodynamic quantities such as thermal expansivity alpha(p), isothermal compressibility k(T) and the specific heat C-p close to the melting point in solid hexadecane. By analyzing experimental data for the thermal expansivity measured at various pressures for constant temperatures of 302 and 325 K, we calculate the pressure dependence of the isothermal compressibility k(T) and specific heat C-p near the melting point in solid hexadecane. We then establish the Pippar...
Thermodynamic properties of the high-pressure phases in solid nitrogen close to phase transitions Akay, Özge; Yurtseven, Hasan Hamit; Department of Physics (2020-11) In this thesis,the physical properties of solid nitrogen are investigated in a wide range of temperature and pressure by analyzing experimental data from the literature.For this investigation, various models are implemented to the experimental data in order to evaluate observed behavior of thermodynamic and spectroscopic properties of solid nitrogen. By means of the calculating Grüneisen parameter which depends on the volume, the pressure and temperature dependence of the Raman and IR frequencies are estima...
Application of the Pippard relations to ammonia near the melting point Yurtseven, Hasan Hamit (1999-09-01) This study gives our application of the Pippard relations to the ammonia near its melting point. The Pippard relations between the specific heat C-P, the thermal expansivity alpha(P) and the isothermal compressibility kappa(T), have been established for the ammonia near its melting point. We have obtained that the Pippard relations are valid for the ammonia. We give here an evidence that on the basis of the experimental data the critical transition in this system near its melting point can be considered as ...
Specific Heat of NH4Cl and NH4BrxCl1-x Crystals Close to the Ferro-Ordered Phase Yurtseven, Hasan Hamit (2009-04-01) This study gives calculation of the specific heat C-VI of NH4Cl and NH4BrxCl1-x under the Ising model for the transition between the disordered (D) and ferro-ordered O(F) phases in these crystalline systems. Our C-VI values which we calculated for x = 0 and x = 0.04, agree both below and above T-c with the observed C-p data from the literature. Our value of a congruent to 0.1 (T < T-c and T > T-c) is in good agreement with the predicted value of 1/8 (0.125) of a 3D Ising model.
