Opacity functions for the hydrogenated (blue) and deuterated (red) SN2 reactions (F− + CH3I / CD3I) at four different collision energies (panels a: 0.7 eV, b: 1.2 eV, c: 1.5 eV, and d: 2.3 eV) using a quantum scattering approach (solid lines) and quasiclassical trajectories (dashed lines) as a function of the total angular momentum Jtot.
