Figure 3. Λ-doublet population ratios for the O(³P)+D₂ reaction at E_coll=25 kcal mol⁻¹.

(a) QM results for v′=0; (b) QM results for v′=1; (c) QCT results for v′=0; (d) QCT results for v′=1. ‘QM' and ‘QCT' represent the ratio of the ICSs calculated on the A′ and A′′ PES, whereas ‘corr-QM' and ‘corr-QCT' are the Π_A′/Π_A′′ ratios after making use of the respective weight factors. The experimental results from ref. 5 are denoted as ‘Exp'. The experimental error bars represent the +1σ statistical uncertainties based on variations in repeated measurements⁵.
