The time evolution of the sokated electron in a series of linear aicohok has been measured. A correlation between the time for monomer rotation TV and the solvation time r, seems to hold for the series. The mechanism of salvation is discussed with reference to the experimental data. J Following the

โฆ Synopsis
We report the duect measurement of electron solvatlon tunes m methanol and ethanol. A plcosecond techmque utihzmg a laser-trqgered flash lamp and a streak camera IS used to momtor the solvation process. The relationship of the solvatlon dynamics to dlelectrx relaxation. local hestmg. and pulse-radiolysls results are presented

The picosecond time-resolved absorption spectra of water and some alcohols were measured by means of 266 nm multiphoton photolysis. The formation time of the solvated electron was estimated and compared with the results obtained by pulse radiolysis and laser photoionization of solute molecules.
The effect of alcohol concentration on the conductivities of solutions of rz-propanol in c-hexane and iso-octane and of t-butanol iu c-hexan= foIIowin,o electron pulse irradiation, are quantitatively consistent with the existence of an equX%rium between mobile electrons in the hydrocarbon and electr
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.
