Abstract

Electron spin resonance (ESR) studies of ClO3 and ClO2 radicals in X-irradiated potassium perchlorate, KClO4, single crystals are carried out to investigate the radiation decomposition pathways. The orientation of the maximum principal component of the Cl-35 hyperfine tensor is determined by ESR and identified with that of the bond ruptured on irradiation. It is found that the weaker Cl-O(2)x2 bonds related by the mirror symmetry survive radiation damage, while the stronger Cl-O(3) and Cl- O(1) bonds get ruptured to form the ClO3 and ClO2 radicals, thus providing evidence for the important role played by the lattice symmetry during radiative decomposition.
