Abstract
BY means of a zinc - mercury lamp which gives sharp spectral lines without accompanying hyperfine structure components or continuous spectrum, Sir C. V. Raman and C. S. Venkateswaran find that the light scattered backwards by glycerine and by phenol exhibits well-defined Brillouin components on either side of the incident lines. The authors infer that the viscosity of glycerine, as usually measured, has little influence on the propagation of thermal compression waves of very high frequencies.
