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

Abstract

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 measurements8. 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.
