Since the successful recording of the transient absorption spectrum of the hydrated electron by Keene1and Hart and Boag2using pulse radiolysis, an enormous amount of experimental and theoretical data3has been presented confirming the existence of the hydrated electron in water (at room temperature). In comparison, however, teh solvated electron inpureice was identified only recently by Eiben and Taub.4They irradiated pure ice samples at 77°K with60Co gamma radiation, recorded and analyzed the absorption spectra of the irradiated samples, and subsequently assigned the observed absorption maximum at 6400 Å (1.9 eV) to the hydrated electron. The observed absorption was thermally stable at 77°K and could be photobleached using visible radiation. Working withpureice samples in the temperature range of 200°K to 260°K, V. N. Shubinet al.5employed the techniques of pulse radiolysis to map the absorption spectra of short-lived species (typical lifetimes of 10−3-10−5sec) in ice, and they attributed the observed transient absorption centered around 6400 Å to the hydrated electron.
