The work described herein was directed towards 1 demonstrating that a particular chemical reaction has lasing potential and 2 attempting to find other systems with lasing potential using rare gas metastable energy transfer. The first part of the program concentrated on the particular reaction C COS to CS CO which pumps the CSa triplet Pi state whose 0-0 transition radiates at 3625A. During the course of the program, an analogous reaction to the one above C COSe to CSe CO was studied. The CSea triplet Pi state was identified for the first time. Studies were performed in a flowtube experiment to demonstrate that the above reactions do indeed occur. The quenching of excited CSe and CS by COS, CO, CO2, N2 and NO was studied. No lasing was observed in any of the above experiments. The second part of the program concentrated on production of emission from molecular states using energy transfer from rare gas metastable atoms. The substances studied were boron trichloride, boron tribromide, carbonyl selenide, germanium tetrachloride, germane, hydrogen fluoride, silane and silicon tetrabromide. The resulting emissions are reported.
