The hard ellipsoid potential model for understanding the mechanism of the rotational energy transfer in a diatomic molecule due to collisions with an atom was explored by performing quasi-classical trajectory calculations on N_{2}-He and N_{2}- Ne systems governed by a sum of pairwise atom-atom Morse interactions. It is found that the conversion of the orbital angular momentum into the angular momentum of the molecule takes place when the colliding atom is very close to the classical turning point ellipsoid. The quantitative measures to define such closeness were introduced. Further, it is observed that nearly 50% of the total angular momentum transfer takes place when the colliding atom approaches the classical turning point ellipsoid and the remaining 50% transfer takes place while the atom bounces back.
