Are dipolar liquids ferroelectric?

چکیده
VH and HV depolarized hyper-Rayleigh scattering spectra were measured for liquid solutions of dipolar CH3CN in nondipolar C2Cl4 at T=300 K. The VH spectrum contains a strong narrow peak due to a slowly relaxing longitudinal orientation mode. This peak is absent in the HV spectrum, and it disappears from the VH spectrum when the CH3CN concentration is reduced to 8%. This observation is consistent with a ferroelectric phase transition predicted to occur when rho mu0(2)=9epsilon0kT=49 D2 M.

Ferroelectric and Dipolar Glass Phases of Non-Crystalline Systems
In a recent letter [Phys. Rev. Lett. 75, 2360 (1996)] we briefly discussed the existence and nature of ferroelectric order in positionally disordered dipolar materials. Here we report further results and give a complete description of our work. Simulations of randomly frozen and dynamically disordered dipolar soft spheres are used to study ferroelectric ordering in non-crystalline systems. We a...
متن کاملSolvation dynamics in imidazolium and phosphonium ionic liquids: Effects of solute motion
Experimental and simulation results of solvation dynamics in ionic liquids have so far been explained in terms of translational motion of the ions constituting the ionic liquids under investigation. A recent theoretical study [Kashyap & Biswas, J Phys Chem B, 114 (2010) 254] has indicated that while translational motion of the constituent ions is indeed responsible for Stokes’ shift dynamics of...
متن کاملThe Influence of the Dipolar Field Effect on the Photochemical Reactivity of Sr2Nb2O7 and BaTiO3 Microcrystals
It has previously been shown that the dipolar field effect spatially localizes photochemical reaction products on the surfaces of macroscopic ferroelectric crystals. In this work, photochemical reactions that deposit insoluble products on the surface have been used to study the dipolar field effect in microcrystals of BaTiO3 and Sr2Nb2O7. In both cases, the patterns of reduced silver on the sur...
متن کاملDimensionality Effects in Dipolar Fluids: A Density Functional Theory Study
Using classical density functional theory (DFT) in a modified mean-field approximation we investigate the fluid phase behavior of quasi-two dimensional dipolar fluids confined to a plane. The particles carry three-dimensional dipole moments and interact via a combination of hard-sphere, van-der-Waals, and dipolar interactions. The DFT predicts complex phase behavior involving firstand second-or...
متن کاملInfluence of Dipolar Fields on the Photochemical Reactivity of Thin Titania Films on BaTiO3 Substrates
The photochemical properties of TiO2 films supported on BaTiO3 were investigated to test the hypothesis that dipolar fields from a ferroelectric substrate would affect the reactivity of the supported film. Photochemical reaction products were formed on the TiO2 surface in patterns that correspond to the underlying domain structure of BaTiO3. As the film thickness increases from 10 to 100 nm, th...
