A study of the mechanism for N,( B 'II,) deactivation by Nz has been carried out using chemiluminescence in the reaction N(%) +N(?S)( +M)+N,(B 'II., v') +NI(A 3Z:, LJ") +hv. Different NZ isotopes were usedas excited and third-body molecules. Ni( B.%,, Y) deactivation w& found to involve 15Nz(X 'X:,
L@t rnoasurcments made during the afterglow oi pure nitrogen and helium-nitrogen mixtures indicate that mutual collisions of the N?(A 'XL) molecule are responsible for the formation of the Nz(C3n,) and Nz(C?nu) states. Results for the latter state arc in agreement with other workers. A value for th
