Abstract :
The rotational spectrum of carbon monoxide (12C16 O) in the far infrared was accurately measured. Calculated CO rotational frequencies derived from a least-squares fit to these data are given for the range J"=0 to 45 and are accurate to ⩽10 kHz (2 σ) for J"⩽28. These frequencies form the most accurate far infrared frequency reference reported by 1993
