Solutions were prepared using Li, Na, K, and Cs over a concentration range of 20 to 1500 $NH_{3}$ molecules per metal atom. The infrared spectra for all cases were very similar to that for a deposit of pure ammonia. However, small changes could be attributed to either cation solvation or perturbed $NH_{3}$ molecules in an electron solvent cage. The optical spectra contained absorption peaks at 10 500 {\AA} and 8000 {\AA} with the 8000 {\AA} peak enhanced at higher metal concentrations. Successively greater dilution of the metal-ammonia glass with argon caused these bands assigned to the solvated electron to narrow and eventually disappear while bands characteristic of the metal atoms isolated in Ar became apparent. The results were interpreted in terms of the modified polaron or cage model of Jortner, However, the symmetric breathing mode of the electron cage, predicted by configurational coordinate calculations, was not found in a Raman study that was hampered by sample film instability in the argon ion laser beam. en_US dc.format.extent 148120 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title THE IR AND VISIBLE SPECTRA FOR THE SOLVATED ELECTRON IN GLASSY METAL-AMMONIA SOLUTIONS en_US dc.type article en_US
