Correlated photofragment product distributions in the photodissociation ofNO2 at 212.8 nm

The 212.8 nm photolysis of NO2 has been studied using REMPI-TOF and LIF tec hniques. Photodissociation occurs via a parallel transition on a time scale which is rapid compared to molecular rotation, producing anisotropic TOF p rofiles. Analysis of state selected NO flight profiles gives the correlated photofragment product distributions and shows that the predominant photodi ssociation channel produces vibrationally excited NO in v = 3 with (OD)-D-1 as the co-fragment. If NO is formed in a rovibrational level for which (OD )-D-1 production is energetically allowed then it is the exclusively produc ed co-fragment. (C) 2000 Elsevier Science B.V. All rights reserved.
