In this study we have correlated the frequency shifts of the acoustic modes to the volume changes by means of our gamma-Gruneisen relations near the lambda-phase transitions in NH4Cl. Using the acoustic frequencies and the length-change data for NH4Cl from the literature, we first calculated the Gruneisen gamma values for the LA modes along the (100) and (110) directions and for the TA mode along the (110) direction. We then predicted the acoustic mode frequencies across the lambda-phase transitions in NH4Cl.

Temperature and pressure dependence of the Raman frequency shifts in anthracene
Ozdemir, H.; Yurtseven, Hasan Hamit (2016-08-01)
In this study, the Raman frequency shifts of phonons and vibrons of crystalline anthracene as functions of temperature (at zero pressure) and pressure (at ambient temperature) have-been calculated using the experimental volume data from the literature. This calculation is performed for six phonons and nine vibrons through the mode Gruneisen parameters which have been determined from the Raman frequency and volume data at various pressures. Our predicted Raman frequencies of the phonon modes decrease with in...
Pressure dependence of the Raman frequency calculated from the volume data close to the ferroelectric-paraelectric transition in PbTiO3
Yurtseven, Hasan Hamit (2017-01-01)
We calculate the pressure dependence of the Raman frequencies of some Raman modes by using the observed volume data through the mode Gruneisen parameters for the ferroelectri-paraelectric transition in PbTiO3. The mode Gruneisen parameters which we have determined using the observed Raman frequencies for the soft modes, increase considerably with increasing pressure toward the transition pressure (PC similar to 11 GPa) from the tetragonal (ferroelectric) to the cubic (paraelectric) phase in PbTiO3. Variatio...
Temperature dependence of the mode Gruneisen parameter in the vicinity of the lambda-transition point in NH4Cl
Karacali, H.; Yurtseven, Hasan Hamit (2006-11-01)
This study gives our relations between the specific heat C P and the Raman frequency shifts (1/v)(partial derivative v/partial derivative T)(p) for the lattice modes of v(5) (144 cm(-1)) and v(5) (174 cm(-1)), when the mode Gruneisen parameter gamma(p) depends on the temperature near. the lambda-transition in NH4Cl (T-lambda = 242.5 K, P = 0).
Analysis of the frequency shifts close to the second order phase transition in NH4Cl
Yurtseven, Hasan Hamit (2001-03-01)
In this study we analyzed observed Raman data for the frequencies of the disorder-induced modes of v(7) (93 cm(-1)) and vs (144 cm(-1)) in the second order phase region of NH4Cl (P = 2.8 kbar). By means of a power-law formula describing the critical behaviour of the frequency shifts 1/v(partial derivativev/partial derivativeT)p for those phonon modes studied, we extract the critical exponent value of a = 0.25, which can also describe the critical behaviour of the specific hear Cp close to the second order p...
Pressure Dependence of the Raman Modes Related to the Phase Transitions in Cyclohexane
Yurtseven, Hasan Hamit (2015-03-01)
The pressure dependence of the Raman frequencies for the v(21) mode is studied by using the volume data at room temperature close to the transitions among the phases of III, IV and V in cyclohexane. By determining the pressure dependence of the mode Gruneisen parameter gamma T in the phases and taking the average values, the Raman frequencies of those modes associated with the phase transitions are predicted through the volume data in cyclohexane. Our predicted Raman frequencies agree with those observed ex...
