CH₄ is one of the major constituents in icy giants, Uranus and Neptune, and H₂S was detected above the clouds in the atmosphere of Uranus. To obtain insights into the structural and chemical bonding properties, we calculated the pair-distribution functions and bond-overlap populations. Our findings could lead to elucidating the existence of H₂S in the atmosphere of the icy giants.
