The calculations, based on close-coupling scheme, were performed for vibrational bands from v = 0 to v = 5, and rotational levels up to j = 5. We provide the pressure broadening and shifting coefficients and the real and imaginary parts of Dicke contribution to the Hess profile. The results are important for astrophysical studies, for example as a reference data for studying the gas giants’ atmospheres. %G English %2 https://univ-rennes.hal.science/hal-01881046/document %2 https://univ-rennes.hal.science/hal-01881046/file/J%C3%B3%C5%BAwiak%20et%20al_2018_Ab%20initio%20line-shape%20calculations%20for%20the%20S%20and%20O%20branches%20of%20H2%20perturbed%20by%20He.pdf %L hal-01881046 %U https://univ-rennes.hal.science/hal-01881046 %~ UNIV-RENNES1 %~ CNRS %~ OSUR %~ IPR %~ IPR-PMOL %~ STATS-UR1 %~ UR1-SPM %~ UR1-UFR-SPM %~ UR1-HAL %~ UR1-SDLM %~ TEST-UR-CSS %~ UNIV-RENNES %~ UR1-MMS
