This study gives our calculations for the Raman frequencies of the rotatory lattice mode in ammonia solid II near the melting point. The Raman frequencies of this mode are calculated as a function of the pressure using the volume data for the fixed temperatures of 230.4 K, 263.4 K, and 297.5 K by means of our Gruneisen relation. Our calculated frequencies can be examined experimentally when the Raman measurements are performed at various pressures for the constant temperatures considered.

Raman frequency shifts calculated from the volume data in naphthalene Ozdemir, H.; Yurtseven, Hasan Hamit (2015-06-15) The Raman frequencies for modes of symmetry Ag and Bg are calculated as functions of temperature (at atmospheric pressure) and pressure (at room temperature) using the observed volume data from the literature through the mode Gruneisen parameters in naphthalene. By determining the temperature and pressure dependence of the isobaric (gamma(P)) and isothermal (gamma(T)) mode Gruneisen parameters, respectively, the Raman frequencies of the modes which were calculated, are in good agreement with the observed fr...
RAMAN FREQUENCIES CALCULATED FROM THE VOLUME DATA AS A FUNCTION OF TEMPERATURE AT HIGH PRESSURES FOR THE DISORDERED PHASE II OF NH4I Yurtseven, Hasan Hamit (World Scientific Pub Co Pte Lt, 2011-02-10) In this study, we calculate the Raman frequencies as a function of temperature for the fixed pressures of 706, 1080 and 6355 bars using the volume data for phase 11 of ammonium iodide. The Raman frequencies calculated here are for the translational optic nu(5) TOM (125 cm(-1)) lattice mode that is located at the zone boundary (M point) of the Brillouin zone of phase II for NH4I. For this calculation the volume data obtained at zero pressure, is used through the mode Gruneisen parameter for the disordered ph...
RAMAN STUDY OF BENZENE NEAR THE MELTING POINT Yurtseven, Hasan Hamit (World Scientific Pub Co Pte Lt, 2013-06-10) We calculate here the Raman frequencies of some lattice modes as a function of pressure at constant temperatures for the solid and liquid phases of benzene. The observed data for the molar volume from literature is used to calculate the Raman frequencies through the mode Gruneisen parameter in benzene.
Raman frequency shifts for ammonia solid I near the melting point Yurtseven, Hasan Hamit (1999-07-01) We have performed in this study the calculation of the Raman frequencies for two translational modes and one librational mode in the ammonia solid I near the melting point. We have obtained the Raman frequencies as a function of temperature for some fixed pressure by means of the Gruneisen relation using the volume data from the literature. Our calculated Raman frequencies can be compared with experimental data available in the literature.
Raman Study of Solid Nitrogen in the beta Phase and Close to the Melting Line Iseri, E. Cetinbas; Yurtseven, Hasan Hamit (Walter de Gruyter GmbH, 2013-02-01) This study gives the Raman frequencies calculated as functions of temperature and pressure for the lattice modes in the solid beta phase and close to the melting line (beta-fluid transition). The experimental volume data from the literature is used to calculate the Raman frequencies for the molecular nitrogen system. Some observed Raman frequencies are also used as the initial data to perform our calculations given here.
