The 7 irradiation of an ethanol glass at 77°K produces solvated electrons (e,) which have an absorption spectrum with hax = 520 nm at 6°K. The conversion of esinto trapped electrons which absorb in the infrared (i.e., electrons in unrelaxed traps denoted by et) has been observed in bleaching es -at

The presence of benzyl in I-propanol, 2-propanal and ethanol glasses at 77 K markedly affects the' changes' which occur in the absorption spectra of the trapped electrons in the pure alcohols after their production by pulse radiolysis. The well known growth in the visible is considerably reduced whi

Photoconductivity of localized electrons, which are not solvated, in r-irradiated ethanol glass at 4 K was studied. Photocurrents of lo-l3 A or larger were stably detected in the wavelength range of 900-2200 nm. The wavelength dependence of the photocurrent reveals that pre-solvated electrons probab
