ESR of O3- trapped in γ-irradiated NaClO3
- 1. Universidade Estadual de Campinas (Brazil). Inst. de Fisica
Description
The ESR spectra of γ-irradiated NaClO3 was analysed at Q-Band, between 110 to 300 K. The single crystals were annealed at 1800C until the spectra indicated the presence of only one paramagnetic center. This center was identified as the ozonide O3-. Four magnetically inequivalent sites per unit cell with symmetry axes along the cube diagonals were observed. The axial symmetry found for the g-tensor was interpreted in terms of molecule rotation around the trigonal axes. A rotational frequency of 2x109 c/s and an activation energy of 10 mev for the rotational motion could be estimated. (author)
