Abstract
The experimental studyof the kinetic behavior of the three electronic-excited Herzberg states of O<sub>2</sub>() in the earth's upperatmosphere provides important basis for the modeling of the upper atmosphere. In thispaper, we introduce the experiments, in which using the flowing afterglow and lasertechniques, they measured the rate constants of the collisional reactions of O<sub>2</sub>(A<sup>3</sup>Σ<sub>u</sub><sup>+</sup>, c<sup>1</sup>Σ<sub>u</sub><sup>-</sup>) withatmospheric molecules. The great difference in the quenching rate constants between thehigh and low vibrational levels of O<sub>2</sub>(A<sup>3</sup>??/font><sub>u</sub><sup>+</sup>, c<sup>1</sup>Σ<sub>u</sub><sup>-</sup>) is alsodiscussed. We also present our views on this problem. In the end, we introduce theprospects of the experimental study of the kinetic behavior of the Herzberg states of O<sub>2</sub>.
