The work performed is primarily directed toward a better spectroscopic understanding of UV laser transitions in selected diatomic molecules. Specifically the work emphasizes the analysis of spectroscopic data for discrete bound-bound and diffuse bound-free transitions in the rare gas monohalide RgX molecules and discrete transitions in the homonuclear halogens. The primary accomplishments of the work include detailed rotational and vibrational analyses of the lasing B to X transition in XeF 3500 A and the lasing D to A transition in Br2 2900 A 2 vibrational analyses of the lasing transitions B to X in XeCl 3100 A and D to A in I2 3400 A, and the nonlasing D to X transitions in XeF 2600 A and XeCl 2350 A analysis of the bound-free B to X and D to X transitions in other RgX molecules, with emphasis on KrCl reanalysis of the D to X UV fluorescence spectrum of I2 determination of potential curves and intensity factors Franck-Condon factors, stimulated emission cross sections for all analyzed systems determination of the energy ordering of the B and C states in KrCl, XeCl, and XeBr, using temperature- dependent emission spectroscopy and characterization of a tesla discharge with respect to its temporal and thermal properties and its total radiant output.
