The raman spectrum of sulphur in the liquid viscous state

Abstract

Abstract The Raman spectra of solutions of sulphur in carbon disulphide at 18°, of sulphur in molten naphthalene at 110°, of liquid sulphur at 120° and of viscous liquid sulphur at 190° have been determined. In both solutions and in the liquid at 120° sulphur is mainly present as S 8 . New frequency shifts are found for the liquid at 190°, proving that transformations in the liquid have taken place. It is not possible however to draw a definite conclusion about the molecular structure of Sμ Probably it consists of open chains of sulphur atoms as K. H. Meyer assumes, coupled with each other to a certain extent, so that a quasi‐crystalline structure of high viscosity occurs. The presence of a low vibrational frequency in the Raman spectrum of the liquid at 190° may be explained in this way.
