Intermediate states of the two-photon ionization of the three aromatic molecules in cyclohexane were investigated using a time-delayed two-color technique. The S1 state is a major intermediate for the two-photon ionization of anthracene and benzo [a] pyrene, while both the S1 and S2 states are intermediates for pyrene. Ionization through the short-lived S2 state was enhanced through autoionization resonance.
