Optical absorption spectra of the solvated electron in n-propane

The optical absorption spectra of the excess electrons solvated in n-propane-h8 and n-propane-d8 at 91 K are calculated in terms of a model presented in a previous paper of ours and compared with the experimental data. We have shown that the band shape and the spectral changes due to the isotope substitution 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.
