Multiphoton Ionization of Phenol in Nonaqueous Solutions: Characterization of the Cation and Ion-Molecule Chemistry

Article abstract of DOI:10.1021/j100166a050

The phenoxy cation has been generated in polar and nonpolar solutions by two-photon ionization of phenol by using 2.5-ns pulses of 266 nm light.The ions have been characterized by pulsed conductivity (ion mobility) measurements and transient absorption spectroscopy with λ_max = 290 - 300 nm and an estimated extinction coefficient of 1300 M^-1 cm^-1.The involvement of the phenoxy ion in ion-molecule chemistry with either neutral solute or solvent molecules has been observed.The kinetics of these processes as well as a proposed reaction mechanism are presented.
