A New Determination of Molecular Dimensions

Abstract

In this study it will be shown that the size of the molecules of a substance in a non-dissociated dilute solution can be determined from the internal friction between the substance and the solvent and from the diffusion of the dissolved substance, if the volume of a molecule of the substance going into solution is large compared to the volume of a molecule of the solvent. A molecule of the dissolved substance will move in the solvent and will influence the internal friction approximately like a rigid body suspended in the solvent.
