Photodissociation to Several Atomic Terms: Near-threshold Resonance for Production of O($^3$P) and O($^1$D) in OH Photodissociation

A theoretical analysis is presented for the multichannel type resonance at energies above the dissociation threshold to O(1D) in the photodissociation of OH. Dissociations to both oxygenic terms O(3P) and O(1D) are treated. Total cross sections for producing these oxygen terms display asymmetric res...

Zusammenfassung:A theoretical analysis is presented for the multichannel type resonance at energies above the dissociation threshold to O(1D) in the photodissociation of OH. Dissociations to both oxygenic terms O(3P) and O(1D) are treated. Total cross sections for producing these oxygen terms display asymmetric resonance due to the quantum interference resulting from complicated interplay of electronic states correlating to these two oxygenic terms. The branching ratios of O(3Pj, j = 0, 1, 2), and the vector properties of O(3Pj, j =0,1,2) and O(1D) display extensive changes near the threshold resonance as the result of the interactions among the electronic states correlated with O(3P) and O(1D).
