The relative intensities of the 4358, 3651, and 3131 Å radiation and the ratios of intensities of the 5461, 4358, 3651, 3131, 3125, and 2967 Å radiation were studied experimentally as a function of position in the negative glow of a Hg&sngbnd;H2dc abnormal glow discharge. These results are displayed in graphical form under conditions of varying H2pressure. Extrapolations of the relative density ratios of the 63D3,2,1and 73S1states were obtained from these intensity measurements. Quenching of the Hg 63P2,1,0states by H2in the negative glow region is discussed.
