From: On the importance of full-dimensionality in low-energy molecular scattering calculations

Cross sections for the CO excitation (jCO = 0 → 1) due to para-H2 (top panel) and normal-H2 (bottom panel) as functions of the collision energy.
The experimental data (filled circles) are from ref. 10. The theoretical curves correspond to three different surfaces: the present 6D V15 potential and the two 4D potentials, V12 and V04, from refs 4,8, respectively.
