Temperature-dependent dielectric relaxation and hydration dynamics of γ-aminobutyric acid in aqueous solution: A broadband dielectric spectroscopy and QTAIM study.
The complex permittivity of aqueous solutions of γ-Aminobutyric Acid (GABA) is measured in the span of 0.5 < GHz < 50 by varying the molal concentration (0-1.0865 mol.kg-1) at T = 298.15 K - 323.15 K. The dielectric spectra were analyzed using a two-relaxation Cole-Cole model to determine the relaxation times, dielectr...
