Analysis of dielectric relaxation characteristics for Isopropanol and pyridine mixtures using time domain reflectometry at 25C

Year: 2025

Type: article

Abstract: - The dielectric relaxation behavior of isopropanol-pyridine mixtures was analyzed using Time Domain Reflectometry (TDR) across the frequency range of 10 MHz to 10 GHz, covering all concentrations. The obtained complex permittivity spectra were modeled using the Cole-Davidson relaxation model to account for the non-exponential distribution of relaxation times typical in polar mixtures. Additionally, the static dielectric constant and relaxation times were derived using a nonlinear least squares fitting method.
