Acoustic investigations of liquids (C8F16 and C9F18) at the various thermodynamic conditions
The fluorocarbons liquids are studied by acoustical method and Brillouin scattering in temperature range from 273 to 313 K and pressure from 0.1 to 50 MPa. Acoustical relaxation in liquid C8F16 with relaxation time of order 10-10 s is discovered. This acoustical relaxation has been analyzed under an assumption of a single vibration relaxation. The measurement of hypersonic velocity by means of Mandelshtam-Brillouin light scattering under high pressure was conducted within two angles of light scattering.
