Abstract
A construction of a light scattering spectrometer and details of sample preparation suitable for a measurement of light scattering spectra are described. Usefulness of membrane filters is emphasized. Measurements of Landau-Placzek ratios are shown to be very useful for the confirmation of optical purity of a liquid sample. Experimental problems of intensity measurements of light scattering spectra are discussed. Brillouin intensities, Rayleigh intensities, Landau-Placzek ratios, and sound velocities are observed for various pure liquids. For the binary mixture of carbon disulfide and chloroform, concentration fluctuations are obtained by measuring concentration dependence of Rayleigh intensities.
