Ground-state NH radicals were generated by 248 mn KrF laser photolysis of NsH4 and their concentration monitored by laser-induced fluorescence at 336 mn, at total pressures near 1 Torr and temperatures between 269 and 377 K. He, Ar, Ns and NsO were used as carrier gases. Rate constants obtained at 3

The rate coefficients of the reactions of NCO radicals with NO and NOz: (1) NCO + NOproducts (293-836 K) and : (2) NCO + NO2products (294-774 K) were measured by means of laser photolysis and laser induced fluorescence technique in the indicated temperature ranges. NCO radicals were produced from th
The rate constant for the NH 3 Ο© NO 2 L NH 2 Ο© HONO reaction (1) has been kinetically modeled by using the photometrically measured NO 2 decay rates available in the literature. The rates of NO 2 decay were found to be strongly dependent on reaction (1) and, to a significant extent, on the secondary
