Model of quantum interference effect on rotational energy transfer within diatomic molecules excited states

Microscopic particle exhibit wave properties because of wave-particle duality of quantum mechanics, numerous examples of quantum interference effect within matter-wave had been discovered. For the singlet-triplet mixed states in diatom molecule, quantum interference present in two transfer roads. The theoretical model of Quantum Interference is described in an atom-diatom system, based on the first-Born approximation of time dependent perturbation theory, taking into account the anisotropic Len- nard-Jones interaction potentials and 'straight-line' trajectory approximation, the approximation conditions of the CQI model is discussed.
