Liquid Water: Dielectric Properties
Dielectric investigations are directly relevant to questions of molecular structure. During the 1930’s many measurements of the dielectric constants of vapors and dilute solutions were made and the electric dipole moments of polar molecules deduced therefrom. Interpretations of the electric dipole moment in terms of bond length, bond angle, and electronegativity gave way to interpretations in terms of molecular wave functions. The electric moment is one of the most important molecular constants and its reproduction is a valuable test of the accuracy of a wave function. The molecular polarizability, or dipole induced by unit electric field, is another important quantity obtainable from dielectric measurements.
