Abstract
We have measured the Raman spectra of intermolecular vibrations of sulfur in the temperature regions of orthorhombic-monoclinic, solid-liquid, and polymerization transitions. The evolution of the Raman spectrum at the first phase transition is discussed in terms of the disorder-induced Raman scattering. The Raman spectra in liquid suggest ordering in the liquid phase. The appearance of the Sn-polymer above the polymerization temperature changes the slopes of the exponential Raman spectra in the liquid.
