Abstract

The digermyl, Ge2H5 (X2A′) and d5-digermyl, Ge2D5 (X2A′), radicals were detected for the first time in low temperature germane and d4-germane matrices at 12K 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 ν6 fundamental at 770cm− 1 Ge2H5 (X2A′ ...
