Dielectric relaxation of glycerol and n-propyl alcohol at high pressure

Abstract

The dielectric relaxation of glycerol and n-propyl alcohol in the supercooled liquid state has been investigated at frequencies from 5 Hz to 13 MHz and at pressures up to 1 GPa. The high-pressure dielectric cell and the measurement procedures are described in detail. A significant broadening of the loss peak is observed for both liquids with increasing pressure. The results are discussed in terms of a many-body relaxation theory which accounts for increasing correlation of the relaxing dipoles at high pressure.
