Accurate calculations of beyond-Voigt line-shape parameters from first principles for the He-perturbed HD rovibrational lines: A comprehensive dataset in the HITRAN DPL format

We report a comprehensive dataset of beyond-Voigt line-shape parameters (pressure broadening and shift coefficients, their speed-dependences, the complex Dicke parameters) for all electric dipole quadrupole transitions within ground electronic state in He-perturbed HD that are present HITRAN database. The determined from generalized spectroscopic cross-sections which we obtain by solving ab initio quantum scattering problem using close-coupling formulation state-of-the-art potential energy surface HD-He interaction. parametrize temperature dependence with double-power-law representation (DPL), recommended Comparison analogous results H2-He system reveals strong isotopologue dependence.
