Photochemistry of O3/HN3 Mixtures

Article abstract of DOI:10.1021/j100339a013

Gaseous mixtures of HN3 and O3 were photolyzed with the 249-nm output of a pulsed KrF laser.The photolysis produces O(¹D) atoms, which react with HN3 to produce N3 radicals and with the N3 radicals to produce electronically excited NO(A²Σ⁺).Rate constants for these reactions were determined from comparison of the experimental NO A -> X emission time profiles with NO(A²Σ⁺) densities calculated from a kinetic model for the system.The rate constants for O(¹D) + HN3 and O(¹D) + N3 were determined to be (3.2 +/- 1.0)E-10 cm³ s^-1 and (1.0 +/- 0.3)E-10 cm³ s^-1, respectively.
