✦ Synopsis
The recombination kinetics of geminate electron-cation pairs in liquid hexane depends on the photoionization wavelength used for charge pair creation. Pairs generated by two-photon ionization of anthracene with 355 nm light exhibit a first half-life for recombination of 108 ps at 191 K; 266 nm light, 930 ps. Longer recombination times are attributed to a greater electron thermalization length in the liquid. The initial pair is studied both by the temperature dependence of the escape probability and by kinetic calculations based on the Smoluchowski diffusion equation.
