Angular Distribution of Light Scattered in Liquids

Abstract
With a Macbeth illuminometer and a Nicol prism, measurements were made of the intensities of the polarized components of the light from a tungsten lamp scattered at angles from 22½ to 157½ degrees in ethyl ether, carbon tetrachloride, carbon disulphide, benzene and water. All of the liquids were fairly, but not completely, free of optical impurities. The observations were found to agree with the theory that the scattering centers in the liquids scattered in the manner of particles small with respect to the wavelength with an additional scattering independent of direction and state of polarization, the amount of the additional scattering depending on the liquid. Deviations from the theory were such as would be accounted for by the optical impurities. For water, strong forward scattering was observed, obviously due to the visible motes.
