Abstract: | Kinetics of NS (B2 Π → X2Π) emission produced by the reaction of active nitrogen with sulfur vapor or sulfur chloride (S2Cl2) has been studied as a function of the total pressure and of the concentrations of atomic nitrogen and sulfur. The B 2Π state of NS is selectively formed by the three-body recombination reaction of N ans S atoms, N(4S) + S(3P) + M →. NS(B 2Π) + M. The highest vibrational level of the B 2Π state observed is ν′ = 12, which gives a lower bound for the dissociation energy of 4.93 eV. |
