✦ Synopsis

Predissociation of the A *Z+ state is treated by an exact theory employing two frame transformation matrices, each of which connects the atomic term limits (q3P) and O('D)) to the correlating adiabatic Born-Oppenheimer states. Resonances corresponding to the higher (v > 7) rovibrational levels of the A '2+ state are predicted to have asymmetric (Fano-type) profiles. The branching ratios of Oc3Pj, j = 0, 1, 2) are shown to be influenced by nonadiabatic interactions in the Franck-Condon region between the A *2+ and dissociative 48-, *8-and 411 st ates. The branching ratios show a strong variation along asymmetric resonances, while remaining energy independent along Lorentzian resonances.
