The intrinsic polarizability tensor of non-polar anisometric molecules from a combination of measurements in a condensed phase

Abstract

Rigid non-polar molecules whose shape is convex and can be approximated by an ellipsoid arc considered. Using the formalism of the "effective polarizability increments" previously developed, it is shown that, starting from combination of different experiments bearing on a solution of such molecules in an isotropic solvent, it is possible to determine the principal elements of the intrinsie (in vacuo) polarizability tensor of the molecule under study. These experiments are the dielectric increment of the solution, its Kerr constant, and the NMR splitting under an electric field of certain atoms of the solute.
