The system of a dispersed phase oscillating in a continuous medium is investigated theoretically with the specific purpose of developing a new technique for the measurement of interfacial viscous and elastic properties. By use of the well‐known models of interfacial mechanics, the decay and frequency of liquid drops oscillating in a gas and of gas cavities oscillating in a liquid are computed as functions of dynamic interfacial properties. The results of the theory indicate, for the size range considered, that the elastic properties dominate over the viscous properties and that dilational effects dominate in the case of the drop in air and shear effects dominate in the case of the cavity in a liquid. The frequency does not seem to depend on the dynamic interfacial properties.
