Analysis of the spectrum of light scattering and ultra- and hypersonic propagation in β-picoline-water solution
The temperature dependence of the intensity of the central component in the spectrum of Mandershtam-Brillouin scattering in a /?-picoline-water solution is investigated. An intensity maximum was observed in the temperature range 60-70 °C. A maximum for the absorption of hypersound and an absence of the temperature dependence of ultraand hypersound, velocities, dV/dTzzQ, were observed in the same temperature interval. At lower temperatures Ä V/Äô = — 0.8 and at higher temperatures dV/Äô = — 3.6.
