Change of Wave-length of Light due to Elastic Heat Waves at Scattering in Liquids

Abstract

SOON after the discovery of the Raman effect, I attempted to find out whether in light scattered in various organic liquids the Raman lines, due to frequencies of the rotation spectrum, are present. These lines should be situated very close (probably within some fraction of an angström) to the incident line. In the course of these experiments a very interesting phenomenon was observed.
