Piezo-Optic Properties of Liquids under High Pressure.

Abstract

A high pressure liquid cell interferometer to measure the variation of refractive index of liquids with pressure to 14 kbars is described. The amount of liquid needed is only 3 c.c. Interferometric measurements on a number of liquids, at high pressure show (i) first experimental proof that the Eulerian frame-indifferent analogue strain E is a more useful strain measure than the Lagrangian strain, (ii) Keane's equation of state best describes each and all liquids, studied, (iii) change in refractive index vs E is linear for all liquids even though the volume strain involved is as high as 33%.
