Abstract: | Electron paramagnetic resonance studies of X-irradiated single crystals of BaCl2-2H2O have been made at room temperature. Four resonance lines are observed which can be grouped into two hyperfine doublets. Angular variation studies were made in the crystallographic ab, bc and ac planes. There are two magnetically equivalent but physically inequivalent magnetic complexes in the crystal lattice which are mutually perpendicular to each other. The paramagnetic species is identified as the hydroperoxy radical and a detailed discussion is made at the end. |
