EPR study of gamma-irradiated sodium thiosulfate pentahydrate single crystals has been carried out at room temperature. The title compound crystallizes in monoclinic system with the unit cell parameters, a =5.94 A, b =21.57 A, c =7.53 A and β =103.58°, with Z =4. The observed lines in the EPR spectra have been attributed to the species of S 2 O − , SO 2 - , S 2 O 2 - , SO 3 - and S 2 O 3 - . Each radical has shown two magnetically distinct sites in monoclinic lattice. The angular variation of EPR spectra has also shown that both S 2 O − and S 2 O 2 - radicals have two groups and each of that has two distinct sites. The principal g values for each site have been calculated. |
