ExoMol line lists. CH3Cl

The line lists, OYT-35 and OYT-37, are suitable for temperatures up to T=1200K and consider transitions with rotational excitation up to J=85 the wavenumber range 0-6400cm^-1^ (wavelengths {lambda}>1.56um). Over 166 billion transitions between 10.2 million energy levels have been calculated variationally for each line list using a new empirically refined potential energy surface, determined by refining to 739 experimentally derived energy levels up to J=5, and an established ab initio dipole moment surface.

The OYT line lists show excellent agreement with newly measured high-temperature infrared absorption cross-sections, reproducing both strong and weak intensity features across the spectrum. The line lists are also available from the ExoMol database.
