Figure 1. QM weighting factors to determine the Π(A′′) and Π(A′) populations.

(a) Reactive cross-sections calculated on the A′ and A′′ PES, which, in the sudden limit, would represent the Π(A′) and Π(A′′)-state resolved cross-sections. (b) The reactive cross-sections calculated for the two Λ-doublet levels once the respective weights have been incorporated. (c) Evolution of the weights for the conversion from the reactivity on the A′ and A′′ PESs to the Λ-doublet populations as a function of the final rotational states. The data were obtained from the QM reaction cross-sections for the O(³P)+D₂ reaction at E_coll=25 kcal mol⁻¹.
