Comments:
Fast flow reactor. Microwave discharge generation of O atoms. Standard O3 ozone source. Rates derived from multiple step mechanism including wall reactions. NaO(A2Sigma+) is first excited state of NaO. Ground state Na(2S) detected with Na lamp resonance fluorescence. Excited state Na(2P) detected using chemiluminesence. O atom detected using resonance absorption O(3S-3P).
