摘要：
Liquid sulfur was studied by Brillouin scattering from the melting point up to 200 degrees C. Polarized spectra show no evidence of the lambda transition. The velocity of sound extracted from the Brillouin spectra agrees with previous ultrasonic measurements. The width of the central line in the depolarized spectra exhibits a maximum near the lambda transition temperature; this is in qualitative agreement with the known maximum in viscosity.
