A detailed product distribution analysis of some potential energy surfaces describing the OH + CO → H + CO2 reaction

► Billions of trajectories were integrated on three surfaces to simulate the reaction. ► Three pseudoquantization methods were used to calculate product distributions. ► Calculated distributions hardly improved the agreement with molecular beam results. ► The normal mode analysis was used to assign discrete vibrational states to CO2. ► A large number of vibrational states, mainly with bending excitation, are populated.
