Abstract The effect of an external electric field on the absorption and the double fluorescence of 4-cyano-N,N-dimethylaniline can be understood, taking into account reaction field induced polarizability effects. If a TICT state conformation emits the a-fiuorescence in dioxane, the permanent dipole moment in this state is only slightly larger than in the equilibrium ground state.

In this work, relaxation processes in polycrystalline PZT films formed on silicon substrates with a quasistatic change in the external electric field are studied. It is shown that dielectric relaxation is characterized by at least three relaxation times, which depend on the direction of self-polarization vector in the film, the magnitude of the polarizing field, and also on the annealing temperature of the PZT films.
