Electronictransitions of protonated benzene (Ã (1)B(2)←X̃ (1)A(1), origin at 325 nm) and α-protonated fulvene (Ã (1)A'←X̃ (1)A', 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 electronictransitions of cyclohexadienyl (onsets at 549 and 310 nm)
