A STUDY ON THE REACTION OF O(D-1) AND N2O BY TRAJECTORY CALCULATION AND TIME-RESOLVED FTIR SPECTROSCOPY

O(D-1) atoms, generated via the laser photodissociation of N2O at 193 nm, reacting with N2O was studied by Time-Resolved Fourier Transform Infrared (TR-FTIR) Spectroscopy The IR emission from NO(v=1-11) was collected at 30 mu s 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 congruent to 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 channel with side-on attack producing N-2 and O-2 was also studied by QCT, where vibrationtionally hot O-2(a(1) Delta(g)) and cold N-2(X(1) Sigma(g)(+)) products are predicted.
