ABSORPTION-SPECTRA OF THE SOLVATED ELECTRON IN HYDROCARBONS

The absorption spectra of the excess electrons solvated in 3-methylpentane-h14, 3-methylpentane-d14, 2-methylbutane, 2,2-dimethylbutane, 2,3-dimethylbutane, and 2,2,3-trimethylbutane at 71 K and n-propane-h8, n-propane-d8 at 91 K are calculated in terms of the theory presented in our previous paper (Abramczyk, H. J. Phys. Chem. 1991, 95,6149) and compared with the experimental data. We have shown that the band shapes and the spectral changes due to the isotope substitution or molecular structure in hydrocarbons can be explained on the basis of the coupling between an excess electron and intramolecular vibrational modes of the solvent in which the electron is stabilized. The effects of molecular structure and the isotope substitution on G(e(t)-) (100 eV electron yield) is discussed.
