between the ethynyl radical and nitrous oxide (C2H+ N2O) using both experimental
methods and electronic structure calculations. A pulsed-laser photolysis/chemiluminescence
technique was used to determine the absolute rate coefficient over the temperature range
570 K to 836 K. In this experimental temperature range, the measured temperature
dependence of the overall rate constants can be expressed as: k (T)(C2H+ N2O)= 2.93× 10 …
