The photochemistry of nitrosyl halides: The X + NOX --> X2 + NO(v) reaction (X = Cl, Br)

Article abstract of DOI:10.1063/1.439371

The primary and secondary photochemistry of NOBr and NOCl has been monitored by detecting infrared fluorescence from vibrationally excited NO following pulsed photolysis of the parent compound with a tunable laser.For wavelengths greater than 480 nm the primary photolysis of NOX to NO + X produces little if any vibrational excitation in the NO product.However, secondary photochemistry produces excited NO through the reaction X + NOX --> X2 + NO(v).From the dependence of the rise time of NO fluorescence on the pressure of NOBr or NOCl at a constant pressure of added argon, it is found that the rate constants for the Br + NOBr and Cl + NOCl reactions are (5.16+/-0.28)x10^-12 and (5.40+/-0.47)x10^-12 cm³ molecule^-1 sec^-1, respectively.The reaction of Br with NOBr produces more NO in v = 3 and/or v = 2 than in v = 1.At 355 nm roughly half of the NO vibrational fluorescence is due to the primary dissociation NOX --> X + NO(v).
