The reactions of electronically excited imidogen NH(a{sup 1}{Delta}) with NO and HCN have been studied at room temperature and low total pressures (20 mbar): NH(a) + NO {yields} products (1); NH(a) = HCN {yields} products (2). NH(a), produced by laser photolysis of HN{sub 3} at {lambda}{sub L} = 308 nm, was detected directly by laser-induced fluorescence (LIF). Measurements of the rate constants were performed under pseudo-first-order conditions, i.e., (R) >> (NH(a)), whereby the time resolution resulted from the delay between the photolysis and the probe lasers. The following rate constants were measured at T = 298 K: k{sub 1} = 1.7 {times} 10{sup 13} cm{sup 3}/(mol s); k{sub 2} = 2.1 {times} 10{sup 13} cm{sup 3}/(mol s).
