Abstract

A Steinheil three-prism spectrograph, used at large angular dispersions in the low-frequency Raman region (0 to 200 or 250 cm⁻¹) has been found to give significantly better spectra, especially in the 0- to 40-cm⁻¹ region, than the previous method. Starunov's theory of the low-frequency Raman spectra of liquids is found to systematize, qualitatively and for some liquids, the observed results, especially an effect of viscosity on the orientation spectra.
