Abstract

Studies in pressure and temperature effects on non-equilibrium superquick processes occurring within condensed media allow us to get much more correct information about mechanisms of intermolecular relations during the molecule media transfer from natural position up to the more strongly packed one. This is proven by experimental results on effective influence of pressure upon vibrational relaxation of benzene, carbon bisulfide, carbon dioxide, tetrachloridemethane, and methane. The main purpose of the paper is to conduct experimental studies of the pressure and temperature effects on vibrational relaxation processes of liquid brombenzene within the range of ultra high frequencies (UHF). These studies are accessible as yet to optical Brillouin spectroscopy in total with low-frequency ultrasound techniques.
