O( 1 D) atoms, generated via the laser photodissociation of N 2 O at 193 nm, reacting with N 2 O was studied by Time‐Resolved Fourier Transform Infrared (TR‐FTIR) Spectroscopy. The IR emission from NO(v1–11.) was collected at 30 μs after the laser was fired. Several instrumental corrections were made to obtain reliable experimental results. The vibrational temperature of the nearly‐nascent NO product was estimated to be Tv 9,000 K. A Quasi‐Classical Trajectory (QCT) calculation of the reaction was performed. The calculated results, corresponding to a head‐on attack mechanism, agree with the experimental data. Additional reaction channel with side‐on attack producing N 2 and O 2 was also studied by QCT, where vibrationally hot O 2 (a 1 Δ g ) and cold N 2 (X 1 ∑ g + ) products are predicted.
