The photodissociation of (C6H6)3 + is studied in the range hν = 0.9-3.0 eV. The electronic spectrum of (C6H6)3 + shows the main band at hν ≈ 1.29 eV and a side band at ≈ 1.02 eV. The (C6H6)3 + ion retains spectroscopic features characteristic of (C6H6)2 +, suggesting that the positive charge is carried by a dimer subunit in (C6H6)3 +. The major fragment ion changes smoothly from (C6H6)2 + to C6H6 + with increasing photon energy from 0.9 to 1.8 eV. The product branching ratios and the kinetic energy of the C6H6 + fragment are consistent with a two-step model for the formation of C6H6 +.
