Popis:	A two laser, double resonance technique is used to determine propensities for collision induced rotational energy transfer by Ar atoms in the N2 B 3Πg (v=3) state. The results show that e/f parity conservation is much more rigorous for the low J values of the 3Π0 component as compared to the 3Π1 or 3Π2 rotational manifolds. These results are in good agreement with the prediction of Alexander and Pouilly [J. Chem. Phys. 79, 1545 (1983)]. The breakdown of e/f parity conservation for the relatively low value of J=7 in the Ω=0 manifold and collisional transfers from this level to the Ω=1 and 2 spin components are discussed in terms of the effects of spin uncoupling from the internuclear axis. There does not appear to be any obvious propensity for J specificity in the collision induced transfer between any two of the three rotational manifolds separated by the spin‐orbit interaction.
