Dielectric Behavior and Intermolecular Forces in Some Liquid Aromatic Methyl Ethers

摘要

Measurements of the static dielectric constant and the density ofohyphen;methylanisole,mhyphen;methylanisole,phyphen;methylanisole, 2,6hyphen;dimethylanisole, and 3,5hyphen;dimethylanisole from 20deg; to 60deg;C, are reported. These data are combined with estimates of the limiting dielectric constant at high frequency in order to obtain information about the interaction of a dipolar molecule with its neighbors. The dielectric constant and loss at 2hyphen;mm wavelength are also reported. These data are used to provide a partial characterization of the dielectric relaxation. The dielectric constants permit more accurate estimates of the highhyphen;frequency dielectric constants than possible previously.
