Vector correlations in the photodissociation of OClO Ã 2A2(ν1, 0, 0)

Using resonant-enhanced multiphoton ionization combined with the time-of-flight method, the photodissociation OClO(Ã 2A2) → ClO(X 2Π)+O(3P) was investigated at two wavelengths which were found to give access to excitation below (397.5 nm) and above (359.7 nm) the predicted exit barrier on the Ã 2A2 surface. The complete angular correlations between the vectors μ, v and J for ClO(v=0) were determined at both wavelengths, providing information on the direct and indirect dissociation pathways on the Ã 2A2 surface of OClO.
