Abstract

NEW measurements recently completed enable us to provide for the first time a set of data to show the dependence upon state of the dielectric polarizations of ammonia (NH3), methylamine (MeNH2), dimethyl-amine (Me2NH), and trimethylamine (Me3N). The essential results are tabulated below and illustrate the influence of the medium in dipole moment determinations1. The figures represent the total polarizations of these four substances calculated at 25° by the usual formulæ.
