Popis:	Both continuous discharge-flow and pulsed methods have been used to investigate the reaction of carbon atoms with azide radicals. In the discharge-flow experiments, C({sup 3}P) atoms were produced by the reaction of CH{sub 4} with excess fluorine atoms. The C({sup 3}P) + N{sub 3} reaction was found to produce CN in the B{sup 2}{Sigma}{sup +} and A{sup 2}II excited electronic states. The rate constant of this reaction was determined from experiments in which mixtures of C{sub 3}O{sub 2} and HN{sub 3} were photolyzed at 193 nm. The results indicated the rate constant to have the value (1.1 {plus minus} 0.2) {times} 10{sup {minus}10} cm{sup 3} s{sup {minus}1}. This value is in accord with trends observed in other atom + N{sub 3} reactions.
