- Aromatic anions absorb in the visible region of the spectrum and energetic considerations suggest that in solution photodetachment may be an important process at these wavelengths. This study reports electron photodetachment cross sections for C/sub 6/F/sub 6//sup -/ for wavelengths between 415 and 700 nm. The anion is generated by electron attachment to solute C/sub 6/F/sub 6/ during an x-ray pulse. Detachment is observed as a change in conductivity induced by a subsequent light pulse from a tunable dye laser. The threshold values are reported for tetramethylsilane, n-butane, cyclopentane, n-pentane, 2,2,4-trimethylpentane, 2,2 dimethylbutane, and neopentane. The thresholds are consistent with an electron affinity of 1.09 +- 0.04 eV for the C/sub 6/F/sub 6/ molecule. Comparison of the data to the absorption spectrum of C/sub 6/F/sub 6//sup -/ shows that for photon energies above threshold the major process is photodetachment. The relationship of photodetachment data to other properties of the excess electrons in these solvents are discussed.
