摘要：
High-resolution depolarized Brillouin light scattering experiments are performed for several liquids over a wide temperature range by using a Sandercock-type tandem Fabry-Perot interferometer. Rayleigh dip is clearly resolved, and the results are analyzed based on two-variable theory. The coupling parameter R in ethyl benzoate shows clear temperature variation. We discuss the relation between the approach of the spectral widths of the two modes and the temperature dependence of R. (C) 2000 Elsevier Science B.V. All rights reserved.
