Аннотация: Our present aim was to prepare and study compounds of Ge(III) in aqueous solutions by means of lowtemperatureradiolysis.We used Ge, GeC14, and GeO 2 of very pure grade. Our primary object of study was aqueous solutionsof Ge(IV) in 4-12 M HC1, which gave a transparent glass when rapidly chilled to 77~ We described themethods of T irradiation at 77~ and of measuring the ESR spectra in [2].After T irradiation of the Ge(IV) solutions in 4-12 M HCI, as well as the known ESR signals of the radicalion CI~ at the H atom, we found three new singlets of comparable intensities (Fig. la, A, B, and C). Insolutions of D20 with DC1 there was no change in the structure of the ESR spectrum. Graphic modeling of thespectrum revealed that it can be regarded as consisting of three independent singlet signals. Table 1 lists theparameters of these signals.
