The reactivity of a molecule striking a surface was found to depend on the diatom's internuclear-axis alignment. State-selected NO+ (X1Σ+, v = 0, J) reagents were aligned through laser ionization prior to their impact with a Ag(111) surface. The yield of scattered O− products was enhanced by “end-on” type collisions, and this preference diminished as the collision energy increased from 35 to 80 eV. Classical trajectory calculations showed that a collision-induced dissociation model is consistent with the experimental observations. |
