Nitroxides, unlike trityl radicals, have shorter T(2)s which until now were not detectable in vivo by a time-domain pulsed Electron Paramagnetic Resonance (EPR) spectrometer at 300 MHz since their phase memory times were shorter than the spectrometer recovery times. In

In rapid scan EPR the magnetic field is scanned through the signal in a time that is short relative to electron spin relaxation times. Previously it was shown that the slow-scan lineshape could be recovered from triangular rapid scans by

TEMPO（2,2,6,6-四甲基哌啶氧基或2,2,6,6-四甲基哌啶1-氧基）及其衍生物在有机氧化反应催化剂中可以作为稳定的硝酰基使用。TEMPO由Lebedev和Kazarnovskii于1960年发现，其具有的稳定自由基性质得益于其庞大的取代基团阻碍了自由基与其他分子之间发生反应。
