Dielectric Relaxation and Molecular Structure. I. Dielectric Relaxation in Substituted Anilines [PDF]

open access: yesBulletin of the Chemical Society of Japan, 1970
Abstract Measurements of static dielectric constant at 1 Mc, refractive index (for sodium D-line) and complex dielectric constant at 9.44 GHz (X-band) have been made to determine the relaxation times and dipole moments of N,N′-dimethylaniline (A), N,N′-diethylaniline (B), o-chloroaniline (C), m-chloroaniline (D) and p-chloroaniline (E ...

On dielectric relaxation equation for anisotropic polarizable reacting fluid mixtures

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2019
In this paper a linear theory for dielectric relaxation phenomena in polarizable reacting fluid mixtures is developed, in the frame of thermodynamics of irreversible processes with internal variables. The microscopic irreversible phenomena giving rise to

Probing the Debye dielectric relaxation in supercooled methanol

open access: yesFrontiers in Materials, 2015
The explanation of the dielectric dynamics in methanol would offer knowledge of the Debye relaxation in supercooled monoalcohols. However, due to the fast crystallization, it is hard to attain the dynamics of pure methanol in the deeply supercooled ...

Memory function for dielectric relaxation

open access: yesThe Journal of Chemical Physics, 2000
The second-order memory function (SOMF) for the dicyclohexylmetyl-2metyl succinate is obtained by using simple numerical manipulation of the experimental dielectric data. According to the prescription given in a previous paper [J. Chem. Phys. 109, 9057 (1998)], the frequency behavior of the real and imaginary parts of the SOMF is discussed in terms of ...
