Laser induced photodissociation of O2+

Abstract

The photodissociation spectrum of O2+, over the energy range 1.7–2.6 eV, has been recorded using tandem quadrupole mass filters and a tunable dye laser. Many of the peaks in the spectrum have been examined at higher resolution and fine structure is observed. A discussion is given of the states involved in the photodissociation. It is believed that processes of both direct dissociation and at least one, but possibly two, types of predissociation are occurring.
