Some considerations on the superfine and spin densities interactions in the SeO2- radical species

The paper presents the study of the paramagnetic centers formed by gamma ir radiation of polycrystaline H2SeO3 and D2SeO3 at room temperature. Accordin g to their EPR parameters and thermal behaviour these centers were attribut ed to the SeO2- radicals. The electron spin densities in the orbitals of se lenium and oxygen aroma Mere calculated. The results obtained by us from H2 SeO3 and D2SeO3 in the form of powder; can compare with those literature ef fected on the monocrystals.
