A spectroscopic linelist for hot water

A new linelist of H2O transition frequencies and intensities is presented. This list greatly improves the accuracy of the energy levels and the transition frequencies over existing hot water linelists. Although it does not cover many high vibrational states of the molecule, it does include all the rotational levels up to J=38. Comparisons with several sets of data (ab initio and experimental) are shown. The accuracy of the linelist should be enough for it to be used to assign laboratory line transitions at high temperature, and to provide water transitions that could be observed in other hot molecular environments including magnetohydrodynamic shocks, circumstellar outflows and active galactic nuclei.
