AbstractApproximate classical trajectory calculations of capture rates are performed for collisions occurring under the influence of a combination of angle‐dependent and isotropic potentials. Results calculated for a wide range of temperatures are in good accord with existing data for ion‐dipole (H3++ HCN), ionquadrupole (OH−+ C2H2), dipole‐dipole (BH + NO), and dipole‐quadrupole (CN + O2)
