THE ASTROPHYSICAL JOURNAL SUPPLEMENT SERIES 95:535, 1994 December INFRARED CO LINE LIST FOR THE X1 SIGMA+ STATE D. GOORVITCH Space Sciences Division, NASA Ames Research Center, Moffett Field, CA 94035-1000; goorvitch@cma.arc.nasa.gov ABSTRACT A complete line list with improved accuracy for all the rotation- vibration transitions of the fundamental, first, and second overtone bands up to v = 20 and J = 149 of the ground state X1 Sigma+ of the seven CO isotopes -- 12C16O, 13C16O, 12C17O, 12C18O, 13C18O, 14C16O, and 13C17O -- is made available to the astronomical community. A line list of the pure rotational transitions up to v = 5 and J = 60 is also made available for these seven isotopes. This line list contains the transition frequency, the lower state energy, the Einstein A-value, the gf-value, the transition strength at 3000 K or 1000 K for the pure rotational transitions, the expectation value of the effective dipole moment operator, and the quantum numbers of each transition. Individual partition functions are reported in the temperature range of 500 to 10,000 K. This line list is available as four text files from the author using an anonymous ftp transfer and in computer-readable form in the AAS CD-ROM Series, Vol. 3. Subject heading: molecular data
