The Photoelectron Spectrum of Dibenzo‐p‐quinodimethane

The lowest states of dibenzo-p-quinodimethane radical cation are 2B1u (7.95 eV); 2B2g (8.66 eV); [2B3g, 2Au, unresolved] (9.1 eV); [2B1u, 2B2g, unresolved] (10.7 eV). This confirms the assignment proposed by Koenig et al. [1] for the states of p-quinodimethane radical cation.
