Abstract: | Chemiluminescence is observed from DN3 at pressures below 100 mtorr following irradiation with the focused output of a CO2 TEA laser. Emission is attributed to ND2(2AI) formed in the reaction ND(a1Δ) + DN3 → ND2 (2A1) + N3. The ND(a1Δ) is produced in the primary photolysis. Time resolved studies of the fluorescence permit determination of the rate constant for the chemiluminescent reaction (2.09 ± 0.31 μs?1 torr?1). Multiphoton dissociation of HN3 by use of a laser wavelength coincident with a hot band absorption is also demonstrated. |
