Experimental Research on Atmospheric Oxygen Band

Using the Ni surface-catalyzed excitation method, we obtained the (0,0) electronic transition spectra of atmospheric oxygen band (b1Σg+→X3Σg-) from the recombination of ground state oxygen atoms O(3P) in flowing afterglow apparatus. We experimentally analysed the kinetic process of deactivation of O2(b) by the wall, which indirectly proved that the concentration of O2(b)changed in a nonsteady-state way in the flowing tube. Meanwhile, the formation mechanism of O2 (b) was simply discussed.
