摘要：

New heterodyne frequency measurements of 12C16O laser transitions were made in the 1995 to 2082 cm-1 (59.81 to 62.39 THz) region. Frequencies of 23 transitions (with lower vibrational quantum numbers, v″, ranging from 1 to 4) were measured. New constants for these low-lying vibrational levels were determined by fitting these data (along with sub-Doppler measurements by Pollock et al. (J. Mol. Spectrosc., 99, 357-368 (1983)), rotational transition measurements, and FTS measurements from Guelachvili et al.(J. Mol. Spectrosc., 98, 64-79 (1983)) to the Dunham expression. Frequency calibration tables calculated from these new constants are reported. These tables provide accurate transition frequencies for the CO laser stabilized to the Doppler-broadened gain profile. © 1990.
