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 solvent molecules has been observed.The kinetics of these processes as well as a proposed reaction mechanism are presented.

Photodissociation dynamics of nitrobenzene molecular ion has been investigated on a nanosecond time scale by mass-analyzed ion kinetic energy spectrometry.Photodissociation has been found to occur through various reaction channels.Three dissociation channels to C6H5O(1+), C6H5(1+), and NO(1+) have been observed together with a consecutive dissociation to C5H5(1+) via C6H5O(1+).The photodissociation rate constant of the molecular ion and the kinetic energy release distributions in each channel have been determined.The rate constant of the second step of the consecutive reaction has been determined in real time also.It has been found that the direct bond cleavage to C6H5(1+) occurs in competition with the rearrangement processes to C6H5O(1+) and NO(1+) on a nanosecond time scale.Statistical theories have been used to gain insight into the dynamics of the reactions.
Infrared multiple-photon dissociation of the nitrobenzene radical cation. A paradigm for competitive reactions

The dissociation of nitrobenzene cation displays a variety of surprising and even apparently nonstatistical reaction behaviors. We have used infrared multiple-photon dissociation experiments to further study the reactions of this system. These experiments along with a previous photoelectron photoion coincidence study indicate that, for some products, the nitrobenzene cation dissociates to form an ion-neutral complex and then reassociates to give the phenyl nitrite cation. A reaction mechanism involving statistical dissociation is shown to account for the experimental data.
