Frequency Dependence of EPR Sensitivity

  • Chapter
EPR: Instrumental Methods

Part of the book series: Biological Magnetic Resonance ((BIMR,volume 21))

Abstract

Contrary to some prior derivations, it is shown that the sensitivity of EPR measurements is, as expected, the same as for NMR, and that in general comparisons of EPR sensitivity as a function of frequency have been pessimistic by one factor of ω. The sensitivity of EPR can increase at lower frequency if the sample size is scaled inversely with frequency.
