Electronic transitions of protonated benzene (A 1B 2X 1A1, origin at 325 nm) and ±-protonated fulvene (A 1A′X 1A′, at 335 nm) trapped in 6 K neon matrices have been detected. The cations were produced from several different precursors, mass-selected, and co-deposited with neon. After neutralization of the cations, the electronic transitions of cyclohexadienyl (onsets at 549 and 310 nm) and ±-hydrogenated fulvene (532 and 326 nm) radicals were identified. Upon excitation of cyclohexadienyl to the B 2B1 state, photoisomerization to an open-chain structure and ±-hydrogenated fulvene was observed.
