Photodissociation Dynamics of HO2 at 220-Mn - Determination of the O(D-1)-O(P-3) Branching Ratio
Photodissociation of the hydroperoxyl radical to give OH + O(D-1,P-3) is investigated at 220 nm using laser-induced fluorescence. We find that the OH fragment is formed in its vibrational ground state with similar to 300 cm(-1) of rotational excitation. Most of the similar to 23 200 cm(-1) of available energy appears as relative translational excitation of the two fragments (similar to 37%) and electronic excitation of the oxygen atom (similar to 61%). An analysis of the OH Doppler profiles reveals that the excited electronic state is of A"symmetry and that similar to 87% of the OH + O product channel results in O(D-1) atoms.
