Adiabatic piezo-optic coefficient of heavy water

Abstract

Among the physical properties of heavy water, its refractive index, which has been studied widely, has been utilized quite often for the estimation of heavy water content, although other methods, such as infrared absorption, are also used. But the change of refractive index of heavy water with pressure was studied recently by us, and in view of its significance for the formulation of any theory for the optical properties of liquids we present here a brief account of the constants for ordinary water and heavy water.
