Photodissociation of ozone at 276 nm by photofragment imaging and high-resolution photofragment translational spectroscopy

The photodissociation of ozone at 276nm is investigated using both state resolved ion imaging and high-resolution photofragment translational spectroscopy. Ion images from both [3+1] and [2+1] resonance enhanced multiphoton ionization of the O(D-1) photofragment are reported. All images show strong evidence of O(D-1) orbital alignment. Photofragment translational spectroscopy time-of-flight spectra are reported for the O-2((1) Delta(g)) photofragment. Total kinetic energy release distributions determined from these spectra are generally consistent with those distributions determined from imaging data. Observed angular distributions are reported for both detection methods, pointing to some unresolved questions for ozone dissociation in this wavelength region.
