Abstract: The pure rotational spectrum of the FeC radical ( X 3 Δ i ) has been measured in the laboratory for the first time using millimeter/submillimeter direct absorption techniques. FeC was created by the reaction of iron vapor, produced in a high-temperature Broida-type oven, and methane gas under DC discharge conditions. Six rotational transitions each were recorded for the two lower spin-orbit ladders of this molecule in the frequency range 240-484 GHz, as well as six transitions for the Ω = 3 ladder of the iron isotopomer 54 FeC. The data were analyzed using a 3 Δ Hamiltonian, and rotational and certain spin-orbit parameters were determined. The observation of SiC in the circumstellar shell of IRC +10216 suggests that metal carbides such as FeC may be present as well.
