A theoretical analysis of the state-specific decomposition of OH(A2Σ+,v′,N ′,F1/F2) levels, including the effects of spin-orbit and Coriolis interactions

Abstract

The state-specific decomposition OH(A2Σ+,v′,N ′,F1/F2)→O(3P J)+H(2S) 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(3PJ) fragment are determined and compared with the results of frequently used approximate models. The predissociation rates of the individual OH(A2Σ+,v′,N ′,F1/F2) levels are also computed and compared with the results of recent experiments. © 1999 American Institute of Physics.
