Abstract

Paramagnetic99Tc complex formed by the reduction of ammonium pertechnetate by ascorbic acid with excess sodium nitrite in concentrated hydrochloric acid was investigated by ESR technique. This complex had total electron spin S=1/2 and the obtained ESR parameters were: g|=2.032, g⊥=2.043, A|=264 gauss and A⊥=108 gauss. Based upon these data it was concluded that the formed species was low spin99Tc/II/ complex.
