These studies, utilizing high pressure, have provided considerable insight into the mechanism of electron transport and electron reactions in hydrocarbon liquids. Electrostriction leads to a significant negative volume change (about {minus}20 cm{sup 3}/mol) for electron trapping in alkanes. Electrostriction around an ion is even greater ({minus}100 to {minus}200 cm{sup 3}/mol). This effect and the fact that the energy level of the electron increases with pressure both contribute to shifts in electron attachment equilibria to favor ions at high pressure. Considerable effort has gone into studies of the mobility, properties and reactions of electrons in nonpolar liquids at or near normal pressures. Only recently have studies been undertaken of the effect of high pressure (up to 3 kbar) on electron behavior in such liquids. Pressures of this magnitude change the electron mobility in both alkane and aromatic liquids, and affect the ground state energy of electrons and stability of ions, which cause changes in the rates of electron reactions. 19 refs., 2 figs., 2 tabs.
