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⁺ - X²Π, B²Π- X²Π, and C ²Π- X²Πwhich correspond to the γ, β, and δ band systems, respectively, as well as minor improvements to transitions within the X ²Πground 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 B²Π-C²Πstates interact. XABC provides comprehensive data for the lowest four doublet states of NO in the region of λ > 160 nm (∼ν< 63∼000∼cm^–1) for the analysis of atmospheric NO on Earth, Venus, or Mars, other astronomical observations and applications. The data are available via www.exomol.com.
