ExoMol line lists – XV. A new hot line list for hydrogen peroxide

A computed line list for hydrogen peroxide, H₂¹⁶O₂, applicable to temperatures up to $T=1250$~K is presented. 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 resulting APTY line list is complete for wavenumbers below 6~000 cm⁻¹ (λ < 1.67~μm) and temperatures up to 1250~K. 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 0.152 \ and our absolute intensities agree better than 10%. The full line list is available from the CDS databas
