We report here our calculated Raman frequencies of the translational mode as a function of temperature for the. fixed pressures of 3.65, 5.02 and 6.57 kbars in the ammonia solid II. They were calculated by means of our Gruneisen relation using the volume data from the literature for all the pressures indicated within the temperature regions close to the melting point in this system. Our calculated frequencies are in very-good agreement with those observed experimentally for this translational mode of the ammonia solid II. This shows that the observed behaviour of ammonia solid II can be described adequately by means of the calculation employed here.

Analysis of the Raman intensities near the phase transitions in ammonium halides
Yurtseven, Hasan Hamit (Elsevier BV, 2008-12-01)
This study concentrates on the temperature dependence of the Raman intensities for the lattice modes in ammonium halides (NH4Cl and NH4Br) close to phase transitions, We predict their intensities using the results of a shell model for the Raman polarizability within the framework of an Ising pseudospin-phonon coupled model.
Spectroscopic modification of the Pippard relation applied for the translational mode in ammonia solid II near the melting point
Yurtseven, Hasan Hamit; Yıldız, İlker (Elsevier BV, 2005-09-01)
This study gives our calculation for the frequency shifts 1/V(partial derivative v/partial derivative T)(P) and the specific heat C-p near the melting point in the ammonia solid II. We establish a linear relationship between C-p and 1/v(partial derivative v/partial derivative T)(P) using the Raman frequencies of the translational mode which we calculated in this system. This leads to the validity of the spectroscopic modification of the first Pippard relation in the ammonia solid II near the melting point. ...
Calculation of the Raman frequency shifts for the alpha phase of solid oxygen
Yurtseven, Hasan Hamit (Elsevier BV, 2017-01-01)
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 through the mode Gruneisen parameter for the a phase of oxygen.
Calculation of the inverse relaxation time and the activation energy as a function of temperature for the Raman modes close to the phase transitions in solid nitrogen
Yurtseven, Hasan Hamit (Elsevier BV, 2021-02-01)
The inverse relaxation time is calculated as a function of temperature for the transitions of alpha - beta (P = 0) and epsilon-delta(loc)-delta (at constant pressures) in the solid N-2. For this calculation, the observed data from the literature are used for the Raman frequency shifts and linewidths (FWHM) of the librational E-g mode (alpha - beta) and the internal modes of v(1) and v(2) (epsilon-delta(loc)-delta) in the nitrogen. From the temperature dependence of the inverse relaxation time, the activatio...
Pressure dependence of the Raman frequencies for the translational mode in ammonia solid II
Yurtseven, Hasan Hamit (Elsevier BV, 2006-12-01)
We study here the translational mode of the ammonia solid II near the melting point by calculating its Raman frequencies as a function of pressure for the fixed temperatures of 230.4, 263.4 and 297.5 K. We perform this calculation of the Raman frequencies using the volume data by means of our Gruneisen relation. The Raman frequency shifts as the volume changes with the pressure, exhibit an anomalous behaviour near the melting point in the ammonia solid II.
