13C16O2, 13C18O2: Emission spectra in the 4.5-μm region

In this paper the same kind of results are given for ¹³C¹⁶O₂,and ¹³C¹⁸O₂ as for ¹²C¹⁸O₂ [D. Bailly and C. Rossetti, J. Mol. Spectrosc.105, 215–228 (1984)]. Forty seven vibrational bands are analyzed from which spectroscopic constants are computed. These constants reproduce wavenumbers with a RMS of the order of 3 × 10^?5 cm^?1 for the best measurements. For each species, a set of molecular parameters is given for Σ-Σ transitions.
