Λ-Related quantum interference of 2Π[Case(a)] diatomic on rotational energy transfer in NO(X2Π) collision with He, Ne and Ar system

In our theoretical studies, the quantum interference on collision-induced rotational energy transfer of atom-1Π diatomic with inert gases was reported. As a further theoretical study of the collision-induced Λ-related quantum interference on rotational energy transfer in an atom-diatom system, a dynamic model of atom-2Π[case(a)] diatomic molecules system is described in this Letter. For the 2Π electronic state in the Hund's case (a) diatomic, degree of the interference is discussed. The interference angles of collision-induced rotational energy transfer of NO(X2Π) in Hund's case (a) with He, Ne and Ar are calculated quantitatively. Based on the time dependent first order Born approximation, taking into accounts the anisotropic Lennard-Jones interaction potentials, the effects of several factors (rotational quantum number experimental temperature and partner) that the interference angle depends on are investigated.
