The work 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 AX molecules, and discrete transitions in the homonuclear halogens. The primary aims of the work are a specific, detailed identification of the laser transitions, including a description of the electronic, and fore discrete systems vibrational and rotational states involved in the transitions determination of potential curves for relevant electronic states calculation of intensity factors -- Franck-Condon factors and R-centroids for discrete systems, Franck-Condon densities and stimulated emission cross sections for diffuse systems evaluation of vibrational relaxation rates in the excited states from the pressure dependence of the emission spectrum and in some cases XeF, I2, Br2 a determination of the kinetics of production and removal of the lower or terminal state of the laser transition. These studies are of relevance to the better understanding of these new lasers and to the development of more complete and correct mathematical models for describing and predicting their performance.
