In cyclohexane solutions, aromatic radical cations are produced by two-photon (248 nm) photoionization of aromatic molecules. A novel excited state chemistry is observed; i.e., excitation of these radical cations with a 532 nm laser pulse, delayed by several microseconds, produces the high mobility cation of cyclohexane. The difference of the signals with and without the 532 nm pulse shows the decay of the cyclohexane radical cation free of complications from geminate ion recombination. The biexponential nature of this decay suggests an equilibrium involving the high mobility cation, such as was proposed to explain previous experimental results.
