The NB(b{sup 1}{Sigma}{sup +}) radical was produced via two-photon photodissociation of NH{sub 3} by use of an ArF excimer laser. Detection of this radical species was achieved by laser pumping the transition NH(b{sup 1}{Sigma}{sup +}) {yields} NH(c{sup 1}II) at 452 nm followed by fluorescence monitoring the NH(c{sup 1}II) {yields} NH(a{sup 1}{Delta}) transition at 326 nm. Deactivation/reaction rate constants for the process NH(b{sup 1}{Sigma}{sup +}) + M {yields} products were measured for the following collisional gases: Ar, N{sub 2}, O{sub 2}, CO{sub 2}, H{sub 2}O, H{sub 2}, CH{sub 4}, and C{sub 2}H{sub 6}. The measured rate constants ranged from 7.1 {times} 10{sup {minus}17} to 1.0 {times} 10{sup {minus}12} cm{sup 3}/(molecule{center dot}s) for deactivation/reaction by Ar and H{sub 2}O, respectively.
