The magnitude of the half-field transition in this technique can be used to measure distances, and the effect of hyperconjugation in cyclic systems being probed by this technique is the subject of the Whiffen effect. Saturating the transitions in this technique by applying an RF field is the basis of the ENDOR experiment. This technique uses an applied frequency of about 9 gigahertz, and both the absorbance and first derivative of the absorbance are reported in this technique. This technique shows absorbances in multiples of the Lande g-factor times the Bohr magneton, which corresponds to a transition from a spin negative ½ state to a spin ½ state. This technique is often used with TEMPO or another nitrone to the sample, which serves as a spin trap. For 10 points, name this type of spectroscopy which can be used to probe unpaired electrons, like the ones found in free radicals.
