We always take the first derivative of ESR spectra in electron paramagnetic resonance spectroscopy to get sufficient signal to noise.

Difference between nmr and esr?

3. Differences between NMR and ESR1)Resonant FrequencyOne important difference between NMR and ESR is that in ESR the resonant frequencies tend tobe much higher, by virtue of the 659-times higher gyromagnetic ratio of an unpaired electronrelative to a proton. For example, a typical magnetic field strength used in ESR spectrometers is0.35 T, with a corresponding resonant frequency of about 9.8 GHz. This frequency range isknown as "X-band", and the spectrometer as an "X-band ESR spectrometer". Such spectrometersare readily available "off the shelf" from a (small) number of commercial sources.X-band ESR spectrometers are typically used to study small solid samples, or non-aqueoussolutions up to a few hundred μL in volume. They cannot be used for biological samples, or forin vivo studies, because of the strong non-resonant absorption of microwaves at 9.8 GHz. Forthat reason, ESR spectrometers (and imagers) have been constructed to operate at lowermagnetic fields, and correspondingly lower frequencies, including at "L-band" (about 40 mT and1 GHz) to study mice and "radiofrequency" (about 10 mT and 300 MHz) to study rats.2) Relaxation TimesThe second important difference between NMR and ESR is the typical relaxation timesencountered. In bio-medical proton NMR the relaxation times T1 and T2 are typically of the orderof 0.1 to 1 sec. In bio-medical ESR the equivalent electron relaxation times are a million timesshorter, i.e. 0.1 to 1 μsec! The extremely short relaxation times have important implications onthe way in which ESR measurements are carried out.

Why do negative electrons fly?

Yea and pigs can also fly: here is an answer from observations of negative bias: We demonstrate "on the fly" electron spin resonance (ESR) in which the defect generation process in the negative bias temperature instability (NBTI) can be observed without recovery contamination. Elevated temperature and modest negative gate bias generates ESR spectra due to E′ center defects. The NBTI generated E′ center spectrum disappears upon stress condition removal, a result consistent with recovery. Our observations support the idea that NBTI is triggered by inversion layer hole capture at an E′ precursor site which leads to depassivation of nearby interface trap precursors.
