Abstract

The vibrational distributions of CO(d 3Δ), CO(a′ 3Σ+), and CO(a 3Π) states produced from CO2 photodissociation at various incident photon energies are calculated using a quantum mechanical theory of poyatomic molecule dissociation and are compared with experiment. It is assumed that CO(d 3Δ) and CO(a′ 3Σ+) are produced via direct photodissociation from the CO2 ground state to a repulsive electronic state. Agreement between theoretical and experimental distribution is obtained. The CO(a 3Π) vibrational distribution calculated using the direct photodissociation assumption could not be made to agree with experiment. Evidence that the CO(a 3Π) dissociation in the photon energy range considered proceeds via a predissociative state of CO2 is given. Comparisons are made with other models of dissociation.
