Abstract

Using the EPR method, an identification of paramagnetic centers formed in TlNO3 under γ-irradiation at 77 and 300 K is performed. Their spectral characteristics, corresponding to the NO3 and NO2 radicals, are determined. The paramagnetic center NO3 is attributed to the NO3 (В) radical, which is thermally stable at 77 K. The NO3 (В) radicals exist in two forms – I and II, which differ by their spatial orientations. The accumulation of paramagnetic centers NO3 and NO2 is investigated and so are the optical reflection spectra of polycrystalline TlNO3 specimens. The final products of radiolysis of thallium nitrate are identified to be the thallium nitrite and peroxonitrite ions.
