ExoMol line lists – XLI. High-temperature molecular line lists for the alkali metal hydroxides KOH and NaOH

Potassium hydroxide (KOH) and sodium (NaOH) are expected to occur in the atmospheres of hot rocky super-Earth exoplanets but a lack spectroscopic data is hampering their potential detection. Using robust first-principles methodologies, comprehensive molecular line lists for KOH NaOH that applicable temperatures up $T=3500$ K presented. The OYT4 list covers 0-6000 cm$^{-1}$ (wavelengths $\lambda > 1.67$ $\mu$m) range comprises 38 billion transitions between 7.3 million energy levels with rotational excitation $J=255$. OYT5 0 - 9000 1.11$ contains almost 50 lines involving 7.9 states $J=206$. available from ExoMol database at www.exomol.com should greatly aid study exoplanets.
