摘要：

Collision-induced dissociation of highly excited NO2 (i.e., mixed B-2(2)/(2)A(1) molecular eigenstates just below D-0) impinging on MgO(100) surfaces has been studied as a function of NO2 internal excitation at an incident translational energy of 4400 cm(-1) by using state-selective NO detection. NO internal energy distributions as well as the average energy transferred per activating collision have been obtained. The results, in particular the NO [(II1/2)-I-2]/[(II3/2)-I-2] population ratios, indicate the presence of exit-channel interactions with the surface that are dependent on collision energy.
