The rate constant for N,(A, v=O) deactivation by H has been measured by monitoring the decrease in the N,(A, v=O) -+N,(X, v=6) emission when H is added to a flow stream containing N\*(A). The value is found to be 5 x lo-" cm3 s-l, with an uncertainty of z 50%.

✦ Synopsis
N2(A'Z2:), the lowest electronically excited state of NZ, has a long and distinguished history due to its role in nitrogen discharges and the nitrogen afterglow. Recently, the production of N,(A) via photolysis and chemiluminescent reactions has been newly explored, and new facets of its reactivity have been uncovered. Nz(A) is unusual, in that its deactivation probability in collision with small molecules spans many orders of magnitude, and is frequently strongly dependent on the vibrational content of NJA). This behavior and the observed product channels can be understood in terms of a simple model for the energy transfer process. Brief comparison with reactions of related species is made.
