Effektive Elektronenzahlen in Dispersionspotentialen. Oberflächenspannung assoziationsfreier Flüssigkeiten. Diamagnetismus / Effective Electron Numbers in dispersion potentials. Surface tension of nonassociated liquids. Diamagnetism

Abstract

Effective electron numbers are proposed for the evaluation of the dispersion forces potentials between polyatomic molecules. Using these potentials improved formulas are derived for the calculation of the surface tension of nonassociated fluids in terms of molar volume and molecular refraction (polarizability). - Critical comments are made on certain connections between polarizability and diamagnetic susceptibility supposed in the literature.
