Notizen:
Brillouin scattering was measured at room temperature in liquid and solid CS2 in a diamond anvil cell up to 70 kbar. In the liquid phase, the acoustic velocity and the refractive index were determined as a function of pressure: The former allowed us to determine the equation of state, ρ=0.206 P0.40+1.144 (1 kbar≤P≤13 kbar) with density ρ in g/cm3 and pressure P in kbar, and the latter was well fitted by the Lorentz–Lorenz relation yielding the pressure-insensitive polarizability of 8.20×10−24 cm3. In the solid phase, the pressure dependence of longitudinal- and transverse-acoustic phonon velocities was determined up to the appearance of black CS2 which was formed at pressures above 70 kbar, and the high optical and elastic anisotropy of crystalline CS2 is discussed.
