 Title: A MOLECULAR BEAM STUDY OF IRIDIUM MONOCARBIDE. Creators: Li, B.- Z.; Steimle, T. C.; Marr, Andrew J. Issue Date: 1995 Publisher: Ohio State University Abstract: A molecular beam optical and molecular beam optical/Stark spectroscopic study of $(0,0) D^{2}\Phi_{7/2} - X^{2}\Delta_{5/2}$ band system of iridium monocarbide, IrC, has been performed. A "cold" beam of IrC was produced in by skimming the products of a laser ablation/$CH_{4}$ reaction source. The $^{191}Ir(I=3/2)$ and $^{193}Ir(I=3/2)$ magnetic hyperfine splitting were analyzed and compared with plausible molecular orbital diagrams. A comparison with the previous with the previous high temperature, Doppler limited $results^{1}$ will be given. Progress on the analysis of the optical Stark spectrum will be reported.
