Radicals, anions of hydrocarbons

Fig. 8. Electronic spectra of the radical anions of hydrocarbons 15—20 and results of open-shell PPP-like calculations. Two arrows indicate the positions of the experimentally found long-wavelength maxima of 15 (Balk, P. et al.. Ref. 8)). The band at 27.3 AK designated by a question mark was attributed to an impurity or to the protonated anion (Hoijtink, G. et al., Ref. 48)). Origin of data systems 15 and 16 (absorption curves), Brandes, K. K., Gerdes, J. J. Phys. Chem. 71, 508 (1967) systems 17—20 (absorption curves), Hoijtink, G. J. and coworkers.
