STUDY OF BRILLOUIN-SCATTERING AND OPTICAL KERR-EFFECT IN 2,2'-THIOBISETHANOL DIMETHACRYLATE

In this work, we report the results of a temperature study of Brilloui n light scattering and the optical Kerr effect in 2,2'-thiobisethanol dimethacrylate (TEDM). Using these methods, we studied the temperature behaviour of the sound velocity and optical Kerr constant in the temp erature range 283-323 K. The temperature dependence observed by two in dependent optical methods displays a characteristic discontinuity at a bout 296-303 K, which may point to a change in intermolecular interact ion in the compound investigated. The results presented are consistent with those obtained previously for the optical Kerr effect and Raman and Brillouin scattering of butane-1,4-diol dimethacrylate (BDM).
