Dipoles dielectric

Table 9. Effective charges (QM, total overlap populations (OP), dipole moments (p), dielectric dipole polarizabilities (a), ionization potentials (IP) and atomization energies (DJ for MO,Cl (M - Tc, Re, and Bh). From [ 1131. ...

Ferroelectric substances perovskites exhibit no permanent dielectric dipoles in the p electric phase (which belongs to the centrosymmetrical symmetry group /w3/w). The dipole moments appear in ferroelectric phase as a result of the spontaneous displacements of ions. Such phase transition is therefore called displacement-type phase transition.

K. Varadarajan It doesn t matter which transition we are observing, whether it s the glass transition or a T>T transition. It depends on the probe that we are using. In TSC studies, the transition temperture occurs at very low tempertures because it corresponds to a low frequency. What we are saying is that the motion of the dielectric dipole is faster than the motion of the mechanical dipole because of the steric hindrance of the >CH-CH3 group. Does that answer your question ...
