✦ Synopsis

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 stabilized upon thermal annealing at 77 K independently and slightI)_ so that their absorption maxima shift to the blue by only (I-2) x lo3 cm-* _ The apparent large shift of the absorption maximum from the IR to the visible region, obsened in the glassy ethanol. is principalI_\ due to the selective decay of the IR-absorbing electrons
