Abstract
The liquid-glass transition in n-propanol is investigated in detail by measuring temperature and pressure dependences of the Brillouin scattering spectra. The experimental data were analyzed using a spectral function based on the theory of the viscoelastic theory and the Vinet equation of state. These yielded the temperature and the pressure dependences of the limiting zero and infinite frequency sound velocities, and the relaxation time. In comparing these results, we found big difference between isobaric cooling and isothermal pressurizing process. The relaxational phenomena in n-propanol are also discussed.
