Ultrasonic Absorption in Heavy Water-Dioxane Mistures

Abstract

Ultrasonic absorption measurements have been conducted in heavy water-dioxane mixtures over the entire composition range at six different frequencies in the range 30–100 Mc/s and at 25°C, using pulse technique. The nature of the α⁄f² versus X_HW (mole fraction of heavy water) curve is found to be quite similar to that observed for water-dioxane mixtures. The results have been analysed in terms of a two-relaxation mechanism proposed by Hammes and Knoche.
