  First infrared spectroscopic characterization of digermyl (Ge2H5) and d5-digermyl (Ge2D5) radicals in low temperature germane matrices

  摘要：

  The digermyl, Ge2H5 (X(2)A') and d5-digermyl, Ge2D5(X(2)A'), radicals were detected for the first time in low temperature germane and d4-germane matrices at 12 K via infrared spectroscopy after an irradiation of the samples with mono energetic electrons. Considering a scaling factor of 0.97, ab initio calculations showed that the most intense absorption of the digermyl radical should be observable for the nu(6) fundamental at 770 cm(-1) Ge2H5 (X(2)A') and 547 cm(-1) Ge2D5(X(2)A'), respectively. The actually experimental results (765 cm(-1) and 561 cm(-1)) are in good agreement with these computed data; we also detected the nu(4)/nu(12) mode of the d5-digermyl radical at 616 cm(-1). These data may aid in the monitoring of time resolved infrared spectroscopy of germane chemical vapor deposition processes and can also guide prospective observations of germanium-bearing molecules in the atmospheres of Jupiter and Saturn in the infrared regime to better understand the chemical evolution of planetary atmospheres under extreme environments.

  The digermene molecule, Ge2H4(X(1)A(g)), and the digermenyl radical, Ge2H3(X(2)A"), 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 nu(3) fundamentals were detected at 1825 cm(-1) and 1317 cm(-1) for Ge2H3(X(2)A") and Ge2D3(X(2)A"), respectively, whereas the digermene molecule H2GeGeH2(X(1)A(g)) and its D4-isotopomer were monitored via their absorptions at 845 cm(-1) (nu(11)) and 1476 cm(-1) (nu(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.
