Abstract

In this study gamma irradiated NaHCO3, CsHCO3 and Na2CO3 were investigated at room temperature. The radicals induced by gamma irradiation in NaHCO3 were found to be (CO3-)-O-. (HCO3-)-O-. and (CO2-)-O-.; in CsHCO3 the species were attributed to (HCO3)-O-.; and in Na2CO3 to (CO3)-O-. and (CO2-)-O-. radicals. The hyperfine parameters for the hydrogen in (HCO3)-O-., and the C-13 nucleus in (CO2-)-O-. radical have been determined. The results were compared with literature data for similar compounds and the EPR properties of the (CO2-)-O-. radical were discussed. (C) 1999 Elsevier Science Ltd. All rights reserved.
