- 中文摘要: O(/sup 1/D) atoms, generated via the laser photodissociation of N/sub 2/O at 193nm, reacting with N/sub 2/O 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.congr.9,000K. 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/sub 2/ and O/sub 2/ was also studied by QCT, where vibrationally hot O/sub 2/(a/sup 1/.DELTA./sub g/) and cold N/sub 2/(X/sup 1/.SIGMA./sub g//sup +/) products are predicted.
