Abstract

A picosecond 266-nm multiphoton laser photolysis method was applied to the investigation of the solvation process of electrons in water and in several pure liquid alcohols. The formation time of the solvated electron obtained by this method in each liquid was revealed to be shorter than that obtained by picosecond pulse radiolysis and by the picosecond two-photon ionization of the solute molecules. By comparing the present results with those obtained by other methods, the effects of the excitation energy, as well as the solvation sphere of the relatively large parent cation on the solvated electron formation process, were elucidated.
