The absorption spectrum of solvated electrons is resolved by super-position of one or several Gaussian-shaped bound-bound bb bands and one bound-continyym bc band. A previously derived equation is applied for the bc band. Energy levels, band amplitudes, widths and contributions are given for tetrahydrofuran, ethylenediamine, hexamethyl phosphoric triamide, water all at room temperature, ammonia - 65C, 3-methyl pentane 77K. Resolution is tentative for ethylenediamine because of insufficient experimental data and for ammonia and water because of inadequacy of the equation for the bc band. Experimental evidence supports this equation for all solvents except ammonia and water. A theoretical limitation is indicated. The energy levels and band contributions are correlated with the nature of the solvent as characterized by the difference between the reciprocals of the optical and static dielectric constants.
