A wavelength table for emission lines of non-metallic elements with transition assignments and relative intensities observed in an atmospheric pressure helium microwave-induced plasma

The emission lines of 10 non-metallic elements (H, C, N, O, F, Cl, P, S, Br and I) excited by an atmospheric pressure helium microwave-induced plasma have been tabulated with their relative intensities and transitions. These non-metallic elements were introduced into the plasma mostly as the vapor of organic compounds, although the emissions of H, N and O were observed due to the impurities in the helium gas. The spectral lines observed in the wavelength region from 190 to 850 nm were assigned with reference to established wavelength tables and tables of atomic energy levels. All emission line intensities of an element were normalized with respect to the most intense emission line of the element taken as 100.
