The Spectrum and Term Analysis of CO I
Abstract
High-resolution spectra of neutral cobalt have been recorded by Fourier transform spectrometry in the region 1745-33333 Å (57300-3000 cm-1) with cobalt-neon and cobalt-argon hollow cathode lamps as sources. Most of the lines exhibit fully or partly resolved hyperfine structure, but the wavenumber uncertainty for the center of gravity of the strongest lines is less than 0.002 cm-1. Of the previously listed energy levels of CO I, 300 have been revised and 22 discarded. In addition, 64 new levels have been found. Wavenumbers and classifications are given for 2442 CO I lines, 287 of which involve the new levels.
