摘要：

The Rayleigh-Brillouin scattering experiment has been carried out for molten ZnCl2. The complete profiles of Rayleigh-Brillouin spectra were obtained at scattering angles of 90-degrees and 140-degrees, and at temperatures ranging from 550 to 1000 K by the use of the carefully purified samples. The remarkable change in the shape of the spectrum with temperature variation has been observed and has been concluded to be due to a structural relaxation in the melt. The spectra have been analyzed by the viscoelastic theory on the assumption of a single relaxation. The sound velocities at the limiting low and high frequencies and the relaxation time have been determined.
