| Abstract: | Aqueous solutions of benzene were irradiated by focussed KrF laser light. The formation of phenol together with varying amounts of 1.3-cyclopentadiene-1-carboxaldehyde was shown by uv absorption measurements. A mechanism for this photo-oxidation via benzene radical cations produced by 2-photon ionization of benzene is proposed. Comparative gas phase laser experiments and experiments with unfocussed laser beams were consistent with previous results using incoherent light sources. |
