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 the35Cl 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)×2 bonds related by the mirror symmetry survive radiation damage, while the stronger Cl-O(3) and Cl-O(l) 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.
