Multiphoton ionization of phenol in nonaqueous solutions: characterization of the cation and ion-molecule chemistry Academic Article uri icon


  • 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 λmax = 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 sovlent molecules has also been observed. The kinetics of these processes as well as a proposed reaction mechanism are presented. © 1991 American Chemical Society.
