Resumo

We have succeeded to record the splitting of the 00 band in the δ = 0.3 Rydberg series of benzene converning to the second ionization limit at 11.49 eV upon reducing the vibrational symmetry to D2h. This measurement is the first direct observation of a splitting of a vibrationless level of a Jahn-Teller active state caused by a vibrational perturbation. This observation leads one inevitably to ascribe the second ionization process in benzene to a removal of an electron from the 3e2g(σ) orbital.
