Atmospheric loss of nitrous oxide (NO) is not influenced by its potential reactions with OH and NO radicals
The rate coefficient for the possible reaction of OH radical with N 2 O was determined to be k 1 < 1 × 10 −17 cm 3 molecule −1 s −1 between 253 and 372 K using pulsed laser photolysis to generate OH radicals and pulsed laser induced fluorescence to detect them. The rate coefficient for the reacti...
