Abstract
AbstractComplex permittivities of aqueous solutions of ethylene‐glycols, HO‐(CH2‐CH2‐O)n‐H (n = 1, 2, 3, 4, 4.1, 8.7, or 13.2, and of ethylene‐glycol dimethylethers, H3C‐O‐(CH2‐CH2‐O)n,‐CH3 (n = 1, 2, or 3), have been measured at 11 up to 13 frequencies in the range 2 to 40 GHz by an interferometric transmission method. A sum of relaxation functions has been fitted to the observed data to yield the hydration number and reorientation time of the hydration water. The values of these parameters are discussed and compared with those for poly (ethylene oxide) of different degree of polymerization and those for other series of organic solutes in order to get insight into the effect of various molecular parameters on the microdynamics of the surrounding water.

- Results for aqueous dioxane solutions are taken from Ref [5]. where the Rs(v)function defined by Equation (7) was fetted to former data with the restrictions (0) =2and = 0. Complex permittivity values as obtained at around 3 8 and 23.8 GHz by Hasted et al. [12] ana static permittivity values of Akerlöf et al. [13] had been used in these calculations The ZhandThvalues quoted here are mean values for three solutions of different solute concentration.
