[en] The digermene molecule, Ge₂H₄(X¹A_g), and the digermenyl radical, Ge₂H₃(X²A''), together with their fully deuterated isotopomers were observed for the first time in low temperature germane and D4-germane matrices at 12 K via infrared spectroscopy upon irradiation of the ices with energetic electrons. The ν ₃ fundamentals were detected at 1825 cm^-1 and 1317 cm^-1 for Ge₂H₃(X²A'') and Ge₂D₃(X²A''), respectively, whereas the digermene molecule H₂GeGeH₂(X¹A_g) and its D4-isotopomer were monitored via their absorptions at 845 cm^-1 (ν ₁₁) and 1476 cm^-1 (ν ₅), respectively. The infrared absorptions of the hitherto elusive digermene and digermenyl species may aid in monitoring chemical vapor deposition processes of germane via time resolved infrared spectroscopy and can also provide vital guidance to search for this hitherto undetected germanium-bearing molecule in the atmospheres of Jupiter and Saturn
