Description


In this work, we present a pruned set of state-to-state rate coefficients (STS rates) for inelastic H_2_:H_2_ collisions in the thermal range from 10 to 1000K. The set includes all relevant rates needed for diagnostics based on the simulation of quadrupole infrared spectra of H_2_. The reported set was obtained from a quantum scattering close-coupling calculation employing a recent version of the MOLSCAT code, a high-level potential energy surface, and rotational energies of the H_2_ molecules with spectroscopic accuracy. These improvements have led to a significant increase in the accuracy with respect to previous computational results. The accuracy of the present STS rates is tested against recently reported experimental rates. Most dominant rates agree with the experiment within a 2{sigma} uncertainty (2 to 6%). In addition to the tables given in the main text, three machine-readable tables are available at the CDS. These tables include all the relevant numerical results of the paper, namely, the excitation and de-excitation STS rates for H_2_:H_2_ inelastic collisions at selected temperatures between 10 and 1000 K, and their functional description for interpolation at any intermediate temperature.
