Photofragment kinetic energy distributions have been measured for O+ fragments from the photodissociation of O3+ over the wavelength range from 4579 to 7525 Å, using a fast ion beam photofragment spectrometer. Three vibrational levels of the ground state of O3+ are observed, and vibrational spacings determined. The partition of energy into rotation and translation of the product O2 molecule is measured for transitions from each of these three vibrational levels. Partition of energy into vibration of the O2 photofragement is also observed. The polarization of the transition leading to dissociation is determined to be more nearly parallel than perpendicular. The results are interpreted in terms of the structure of O3+ and the dissociation process, and are compared with results from the photoionization of O3, and with theoretical calculations.
