β¦ Synopsis
Kinetic laser saturation experiments are reported in which evidence is presented for homogeneous photobleaching across 1.5 eV of the outical absorption band of solvated electrons in a ran,ge of alcohols Competition between vibronic relaxation and photochenktry of the excited state is discussed.

Following pulsed irradiation of disordered solids, optical absorption of trapped electrons decays in the far red and increases in the visible. The random-walk model of Scher and Control, quantitatively apphcable to electron mobility by timeof-flight, supports hopping to successively deeper traps. Ba
Careful elamination of glassy ethanol, and other alcohols for comparison, y-imdiated at 4.3, I;, indicates that the initial absorption spectrum of trapped electrons has t\ro components: one is due to IR-absorbing electrons and the other to visibleabsorbing electrons. Both the electrons are stabilize
