The predictive power of the calculated line lists of carbon monoxide

E. S. Medvedev, V. G. Ushakov

Abstract

The ability of our semi-empirical irregular dipole-moment functions (2022) and (2025) to predict the intensities of the yet unobserved lines, as well as to describe the observed ones not used in the fitting, is demonstrated by comparison with recent measurements in the 0-0, 1-0, 3-0, and 7-0 bands.

  • Figure 1: Comparison of the Einstein A coefficients for the $v$-0R(0) lines calculated with the Irregular (empty circles) and Rational (full circles) DMFs of Ref. Medvedev22 fitted to the updated data base of Ref. Ushakov25CO with the predictions of the polynomial DMF fitted to the ab initio DMF in Ref. Zobov25 (crosses). $E^\prime$ is the energy of the upper level in cm$^{-1}$, $\omega=2143$ cm$^{-1}$. The NIDL line is drawn for the $v\le20$ overtone transitions excluding the 5-0 anomaly and two neighboring lines.
