Dielectric Relaxation Spectroscopy
C.M. Roland (December 17, 2014) Introduction Impedance spectroscopy and dielectric relaxation measurements yield the same information; however, their purpose and analysis methods differ. Impedance spectroscopy is typically used to probe electrochemical processes, while dielectric relaxation data, almost invariably expressed in the complex permittivity representation, provide information on dyna...
متن کاملDielectric relaxation in dimethyl sulfoxide/water mixtures studied by microwave dielectric relaxation spectroscopy.
Dielectric spectra of dimethyl sulfoxide (DMSO)/water mixtures, over the entire concentration range, have been measured using the transmission line method at frequencies from 45 MHz to 26 GHz and at temperatures of 298-318 K. The relaxation times of the mixtures show a maximum at an intermediate molar fraction of DMSO. The specific structure of mixtures in different concentration regions was de...
متن کاملMolecular motions in chitosan studied by dielectric relaxation spectroscopy.
Neutralized and nonneutralized chitosan films subject to different thermal treatments were studied by dielectric relaxation spectroscopy from -130 to +150 degrees C in the frequency range between 20 Hz and 1 MHz. Two main relaxation processes, both arrhenian type, were detected: process I at temperatures below 0 degrees C with a mean activation energy of 49 +/- 1 kJ mol(-1), which has the chara...
متن کاملDielectric relaxation of electrolyte solutions using terahertz transmission spectroscopy
We use terahertz ~THz! transmission spectroscopy to obtain the frequency dependent complex dielectric constants of water, methanol, and propylene carbonate, and solutions of lithium salts in these solvents. The behavior of the pure solvents is modeled with either two ~water! or three ~methanol and propylene carbonate! Debye relaxations. We discuss the effects of ionic solvation on the relaxatio...
متن کاملUltraslow dielectric relaxation process in supercooled polyhydric alcohols.
Complex permittivity was obtained on glycerol, xylitol, sorbitol and sorbitol-xylitol mixtures in the supercooled liquid state in the frequency range between 10 microHz and 500 MHz at temperatures near and above the glass transition temperature. For all the materials, a dielectric relaxation process was observed in addition to the well-known structural alpha and Johari-Goldstein beta relaxation...
