Popis: Spectra of the solvated electron were determined at --55, -65, and --75 deg C for solutions in NH/sub 3/ and in NH/sub 3/ 0.08 M in Nal by extrapolations to inflnite dilution. Spectra obtained for Na-NH/sub 3/ solutions and for Na-NH/ sub 3/-Nal solutions were shown to fulflll the expectations of a two absorber model. The data rule out the possibility that the second absorber incorporates only a single solvated electron. The data support the assumption that the second absorber involves a binary combination of solvated electrons. Spectra of the second absorber are obtained at all three temperatures and for solutions in both NH/sub 3/ and in NH/sub 3/ 0.08 M in Nal. Spectra due to Gold and Jolly appear to be characteristic of the second absorber and not the solvated electron. (auth)
