Theory of Electric-Field Effects on Electron-Spin-Resonance Hyperfine Couplings

摘要: A quantum mechanical theory of the effects a uniform electric field on electron-spin-resonance hyperfine couplings is presented. The electric-field are described in terms perturbation coefficients which can be used to probe local symmetry as well strength at paramagnetic sites solid. Results presented for first-order describing Bloembergen effect (linear coupling tensor) O atom and OH radical. {copyright} {ital 1997} American Physical Society}
