ExoMol line lists for H216O2

A semi-empirical high accuracy potential energy surface is constructed and used with an ab initio dipole moment surface as input TROVE to compute 7.5 million rotational-vibrational states and around 20 billion transitions with associated Einstein-A coefficients for rotational excitations up to J=85. The result- ing APTY line list is complete for wavenumbers below 6000cm^-1^ (wavelength <1.67um) and temperatures up to 1250K.

Room-temperature spectra are compared with laboratory measurements and data currently available in the HITRAN database and literature. Our rms with line positions from the literature is 0.152cm^-1^ and our absolute intensities agree better than 10%.
