摘要：

We report the observation of the O- + H2O --> OH- + OH ion-molecule reaction following photodissociation of O-2(-) within the O-2(-).H2O ion-dipole complex. Photoexcitation of the O-2(-) A (IIu)-I-2 <-- X (IIg)-I-2 dissociative transition in the 200-300 nm region initiates the reaction. The O-.H2O reaction intermediate is the dominant photoproduct throughout the A-X band, while some geminate recombination (approximate to 2%) is observed at 4.66 eV (266 nm), 0.57 eV above the O-2(-) dissociation threshold.
