VECTOR CORRELATIONS IN THE PHOTODISSOCIATION OF OCLO-(A)OVER-TILDE(2)A(2)(NU(1),0,0)

Using resonant-enhanced multiphoton ionization combined with the time- of-flight method, the photodissociation OClO((A) over tilde(2)A(2)) -- > ClO((XII)-I-2) + O(P-3) was investigated at two wavelengths which we re found to give access to excitation below (397.5 nm) and above (359. 7 nm) the predicted exit barrier on the (A) over tilde(2)A(2) surface. The complete angular correlations between the vectors mu, upsilon and J for ClO(upsilon = 0) were determined at both wavelengths, providing information on the direct and indirect dissociation pathways on the ( A) over tilde(2)A(2) surface of OClO.
