Abstract

Steric effect for the XeF* (B, C) formations in the oriented Xe* (3P2, MJ = 2) + oriented NF3 reaction has been observed as a function of the mutual configuration between the molecular orientation and the atomic orientation in the collision frame. Molecular steric opacity function has been determined as a function of the atomic orbital alignment (LZ′) in the collision frame. The larger reactivity at the side with the smaller reactivity at the molecular axis direction is observed for the XeF* (B, C) channels at each atomic orbital alignment. A good correlation between the shape of the molecular steric opacity function and the molecular geometry of NF3 is recognized. The LZ′ selectivity in the molecular steric opacity function is different between the XeF* (B, C) channels; in the sideways direction, the XeF* (B) channel is favorable at LZ′ = 0, while the XeF* (C) channel is favorable at |LZ′| = 1. In contrast, at the molecular axis direction, the XeF* (B) channel is favorable at |LZ′| = 1, while the XeF* (C) channel is favorable at LZ′ = 0. We propose the collision-induced harpoon mechanism for the XeF* (B, C) formation in the Xe* (3P2) + NF3 reaction.
