Abstract
Liquid sulfur was studied by Brillouin scattering from the melting poi nt up to 200 degrees C. Polarized spectra show no evidence of the lamb da transition. The velocity of sound extracted from the Brillouin spec tra agrees with previous ultrasonic measurements. The width of the cen tral line in the depolarized spectra exhibits a maximum near the lambd a transition temperature; this is in qualitative agreement with the kn own maximum in viscosity.
