This study gives our analysis of the Raman bandwidths using the soft mode-hard mode coupling model applied to ammonium halides. The temperature dependence of our observed bandwidths for the nu(5)(174 cm(-1)) Raman mode of NH4Cl and nu(5)(177 cm(-1)) Raman mode of NH4Br, is analyzed close to phase transitions. From our analysis, we obtain beta = 0.13 as the values of the critical exponent for the order parameter in the first order phase region for the ammonium halides.

Temperature dependence of the damping constant and the order parameter close to the lambda phase transitions in ammonium halides Yurtseven, Hasan Hamit (Elsevier BV, 2006-10-01) This study gives our calculation for the damping constant, using the expressions derived for an Ising pseudospin-phonon coupled system in the ammonium halides (NH4Cl and NH4Br). For this calculation of the damping constant, we use the temperature dependence of the order parameter calculated from the molecular field theory. We predict here the damping constants for the v(5) (174 cm(-1)) and v(5) (177 cm(-1)) Raman modes of NH4Cl and NH4Br, respectively, below T-lambda and compare them with our observed bandw...
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.
Quantum chemical studies on some seleanaphthalene derivatives Türker, Burhan Lemi (Elsevier BV, 2005-04-01) Quantum chemical studies on certain selenanaphthalene derivatives (having a keto or enol group and also Se atom in five- or six-membered ring system fused with naphthalene moiety) have been carried out using PM3 method at the level of restricted Hartree-Fock approach. The aquated systems have also been considered.
Raman frequency shifts of an internal mode near the tricritical and second order phase transitions in NH4Cl Yurtseven, Hasan Hamit (Elsevier BV, 2005-12-01) This study gives our analysis for the frequency shifts of the nu(2)(1708 cm(-1)) Raman mode in NH4Cl close to its tricritical (P = 1.6 kbar) and second order (P = 2.8 kbar) phase transitions. From our analysis, we extract the values of the critical exponent which describes the critical behavior of the Raman frequency shifts for this internal mode for the pressure conditions studied in NH4Cl. Our exponent value of alpha approximate to 0.2 for the tricritical phase transition is close to the values of 1/16 (T...
Development of sensitive analytical methods for the determination of thallium at trace levels by slotted quartz tube flame atomic absorption spectrometry Ari, Betul; BAKIRDERE, Sezgin; Ataman, Osman Yavuz (Elsevier BV, 2020-09-01) A simple, sensitive and economical technique is needed for the determination of thallium and this study demonstrates the different analytical strategies were developed using atomic absorption spectrometry (AAS). In order to improve the sensitivity of flame atomic absorption spectrometry (FAAS), a basic slotted quartz tube (SQT) was used for the thallium determination. In the first strategy, mixing propanol (100 mu L) and Tl standard solution (500 mu L) under the optimum conditions, namely solvent assisted S...
