Two Photon Ionization of Benzene in Methanol and Cyclohexane Solution

S. Tagawa , G. Beck and W. Schnabel

Abstract

Irradiation of benzene with 15 ns flashes of 265 nm light caused ionization as evidenced by optical absorption measurements. In the case of dilute methanol solutions solvated electrons were formed. The yield depends on the intensity of the incident light I as ϕ (es̄olv) ∝ I1.8. In the case of cyclohexane solution dimer radical cations were detected by their absorption between 600 and 1100 nm. O2 enhances the yield of dimer cations because it scavenges electrons, thus impeding ion recombination.
