The state-specific decomposition OH(A (2)Sigma(+),upsilon＇,N＇,F-1/F-2)-->O(P-3(J))+H(S-2) is investigated using multichannel scattering theory based on potential energy curves, spin-orbit couplings, and Coriolis couplings, obtained from multireference configuration interaction wave functions. The fine-structure branching fractions of the O(P-3(J)) fragment are determined and compared with the results of frequently used approximate models. The predissociation rates of the individual OH(A (2)Sigma(+),upsilon＇,N＇,F-1/F-2) levels are also computed and compared with the results of recent experiments.
