title: Dipolar interactions in liquids and linear dielectric relaxation spectroscopy.
abstract: Linear dielectric relaxation studies performed on two isotropic liquids composed of the molecules of the same moment of inertia and a quite different polarity: C10H21-O-Ph-COO-Ph-CN (the dipole moment of about 5 D) and C10H21-O-Ph-OOC-Ph-CN (2.5 D) showed that, at given temperature, the relaxation times corresponding to the rotation around the short axis of the two kinds of molecules coincide to each other, regardless the polarity of the molecules and their abilities to accomplish dipolar aggregation. The studies allow one to estimate the lifetime of the intermolecular aggregates due to the dipolar interactions in liquids as no longer than 0.1 ns.
