ExoMol Molecular Line Lists – XLII: Rovibronic Molecular Line List for the Low-Lying States of NO

An accurate line list, called XABC, is computed for nitric oxide which covers its pure rotational, vibrational and rovibronic spectra. A mixture of empirical and theoretical electronic transition dipole moments are used for the final calculation of 14N16O rovibronic A 2Σ+ – X 2Π, B 2Π – X2Π and C 2Π – X 2Π which correspond to the γ, β and δ band systems, respectively, as well as minor improvements to transitions within the X 2Π ground state. The work is a major update of the ExoMol NOname line list. It provides a high-accuracy NO ultraviolet line list covering the complicated regions where the B 2Π-C 2Π states interact. XABC provides comprehensive data for the lowest four doublet states of NO in the region of λ > 160 nm (ν̃ < 63 000 cm−1) for the analysis of atmospheric NO on Earth, Venus or Mars, other astronomical observations and applications.
