Going Low in a World Going High: The Physiologic Use of Lower Frequency Electron Paramagnetic Resonance

Yakov Sergeevich Lebedev was a pioneer in high frequency EPR, taking advantage of the separation of g-factor anisotropy effects from nuclear hyperfine splitting and the higher frequency molecular motion sensitivity from higher frequency measurements(8). This article celebrates a second EPR subfield in which Prof. Lebedev pioneered, EPR imaging. (9) We celebrate the clinical enhancements that are suggested in this low frequency work and imaging application to animal physiology at lower-than-standard EPR frequencies.
