Notizen: Näherungsforniel für den Koeffizienten der thermischen Ausdehnung von assoziationsfreien flüssigen Nichtelektrolyten / Approximation Formula for the Thermal Expansion of Nonassociated Nonelectrolytic Liquids

Abstract

For the calculation of the thermal expansion of nonassociated liquids in terms of molar volume, mol refraction and the "effective electron numbers" a corrected approximation formula is proposed. The thermal expansion of 26 solvents is calculated. - The usefulness of the "effective electron numbers" for the derivation of numeric data for dispersion force potentials of polyatomic molecules is affirmed once more.
