The molecules were produced by reaction of laser ablated cobalt atoms with $1% SF_{6}$ seeded in He under supersonic jet conditions. The $0-0$ and $1-0$ bands of the system were probed with a Coherent 699-29 cw ring dye laser giving experimental linewidths on the order of 200 MHz. The appearance of the spectrum at low resolution where a strong $R-$, and weaker $Q-$, and P-branches were observed is indicative of $\Delta \Lambda = \Delta\Omega =+1$. This and analysis of the first lines yields a value of omega=4 for the ground state, consistent with earlier work, and a value of omega=5 for the upper state. Comparison with calculations on CoH has allowed this transition to be assigned as the $[20.6]^{3}\Gamma_{5} - X^{3}\Phi_{4}$ transition. The molecular constants derived from a nonlinear least squares fit to the data will be presented. en_US dc.format.extent 339107 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.title ANALYSIS OF THE HYPERFINE STRUCTURE IN THE [20.6]5 - X4 TRANSITION OF COBALT MONFLUORIDE. en_US dc.type article en_US
