Table 1. Ratio of the relative intensities of the light emission of the molecular bands of OH, N₂(C) and N₂ ⁺ and of the atomic lines of He and O from the plasma jet in the absence or presence of a shielding gas of pure O₂.

Gas species	Ratio (no shielding/O₂ shielding)
OH (309 nm)	33
N₂(C) (337 nm)	2155
N₂⁺ (391 nm)	1475
He (706 nm)	0.72
O (777 nm)	0.22

The data are derived from the experimental values measured from the emission spectra of each species shown in Fig. 10. Note that the emission intensity of the molecular bands of OH, N₂(C) and N₂⁺ drop drastically in the presence of the shielding gas of pure O₂.
