On the reaction of the NH 2 radical with NO at 295-620 K
Abstract
The reaction of the NH 2 radical with NO, NH 2+NO→ k1 products, was investigated using intracavity laser spectroscopy. The temperature dependence of k1( T) over the range 295-620 K is well approximated by the expression k1( T)=(2.0±0.4)×10 -11×( T/298) -2.2 cm 3 s -1. The branching ratios for the OH radical, α=( k1b+ k1c)/ k1, where NH 2+NO→ k1b N 2H+OH→ k1c N 2+H+OH, obtained at different temperatures over the range 295-620 K are as follows: α(295 K)=0.1±0.02; α(470 K)=0.14±0.03; α(620 K)=0.2±0.04.
