We study here the temperature dependence of the Raman frequencies for the overtone 2 nu(6) of the librational mode nu(6) in phase III of NH4I. By using the experimental infrared frequencies of the 2 nu(6) mode, we predict the Raman frequencies of this overtone 2 nu(6) mode as a function of temperature at atmospheric pressure in phase III of NH4I. Our calculations indicate that the Raman frequencies of 2 nu(6) exhibit anomalous behavior at around 110 K (P = 0) in phase III of NH4I, as observed experimentally.

CALCULATION OF THE RAMAN FREQUENCIES AT LOW PRESSURES AND TEMPERATURES (sigma-PHASE) SOLID NITROGEN
Yurtseven, Hasan Hamit (World Scientific Pub Co Pte Lt, 2013-09-20)
We calculate the Raman frequencies of the E-g mode and, the low and high frequency T-g mode as a function of temperature at a constant pressure of 2.85 kbar in the alpha-phase of solid nitrogen. The Raman frequencies of those lattice modes are calculated using the volume data from the literature at various temperatures (2.85 kbar) for the alpha-phase of solid N-2 through the mode Gruneisen parameter. Our predicted Raman frequencies can be compared with the experimental data and by this method the Raman freq...
ANALYSIS OF THE FREQUENCY SHIFT AND THE LINEWIDTH AS A FUNCTION OF TEMPERATURE IN SOLID NITROGEN
KURT, MUSTAFA; Yurtseven, Hasan Hamit (World Scientific Pub Co Pte Lt, 2011-10-30)
The temperature dependence of the frequency shift and the linewidth is studied using the expressions derived from the anharmonic self-energy. The functional form of the frequency shift is fitted in this study to the experimental data for the R(1) fluorescence line of ruby sample as a function temperature at zero pressure, instead of using empirical nu-P and nu-T relations in the ruby fluorescence method as given in the literature, in particular, for the solid nitrogen. We also demonstrate in this study the ...
CALCULATION OF THE DAMPING CONSTANT AND ACTIVATION ENERGY FOR RAMAN MODES IN (NH4)(2)SO4
Yurtseven, Hasan Hamit; Kiraci, A. (World Scientific Pub Co Pte Lt, 2011-06-20)
The temperature dependence of the damping constant is calculated for various Raman modes in (NH4)(2)SO4 by the expressions derived from the soft mode hard mode coupling model and the energy fluctuation model. The expressions for the damping constant are fitted to the measured Raman bandwidths and then the activation energies are extracted, which are equal to similar to 0.2 eV for the Raman modes studied. The damping constant of a soft mode is also calculated and the activation energy (similar to 0.1 eV) is ...
DETERMINATION OF TRAPPING CENTER PARAMETERS OF Tl2Ga2S3Se LAYERED CRYSTALS BY THERMALLY STIMULATED CURRENT MEASUREMENTS
YILDIRIM, TACETTİN; Nasser, H. A.; Hasanlı, Nızamı (World Scientific Pub Co Pte Lt, 2010-06-10)
We have carried out thermally stimulated current (TSC) measurements on as-grown Tl2Ga2S3Se layered single crystals in the temperature range 10-60 K with different heating rates of 0.6-1.5 K s(1). The data were analyzed by curve fitting, initial rise, and peak shape methods. The results were in good agreement with each other. Experimental evidence was obtained for trapping center in Tl2Ga2S3Se crystal with activation energy of 11 meV. The capture cross section and concentration of the traps were found to be ...
Calculation of the specific heat for the first order phase transition in NH4Br
Yurtseven, Hasan Hamit; Sherman, WF (World Scientific Pub Co Pte Lt, 1998-11-01)
We calculate in this work the specific heat C-VI using the predictions of an Ising model for the NH4Br crystal (T-C = 234 K, P = 0). Our calculated C-VI values are in good agreement with the experimentally observed C-p data from the literature. This shows that the observed behavior of NH4Br can be described adequately in the lattice region under an Ising model studied here.
