Marcador de spin que foi usado para estudar a migração molecular e a estabilidade no longo prazo de sementes e pólen. Ele foi covalentemente ligado a oligonucleotídeos para preparar uma sonda de DNA sensível a ressonância paramagnética eletrônica. O éster acetoximetílico é uma sonda sensível a esterases que atravessa a barreira hematoencefálica para imageamento por ressonância paramagnética eletrônica/tomografia computadorizada.
Marcador de spin. A forma aniônica foi usada para determinar os coeficientes de distribuição de solubilizatos neutros em micelas aniônicas.[1]
Usado no preparo de uma tetrafenilporfirina com um radical nitroxila.[2]

Much outstanding progress concerning the application of ESR spectroscopy/imaging in the biomedical field has been made in recent years. The literature in this field has already been specifically covered by several reviews. The aim of this article is to provide
Contrast agents have been investigated in an effort to increase the differences between the proton relaxation times of normal and pathologic tissue, and thus improve the ability to detect regions of pathology. Data on the oxygen-dependent metabolism of three nitroxides

Clearance of the nitroxide radicals, hydroxy-TEMPO and carboxy-PROXYL, in whole-mouse lung was directly measured by in vivo ESR. After injecting a nitroxide radical, distribution of the nitroxide radical all over the lung was confirmed by ESR imaging. The ESR signal
The relationship between molecular mobility (tauR) of the polar spin probe 3-carboxy-proxyl and water content and temperature was established in pea axes by electron paramagnetic resonance (EPR) and saturation transfer EPR. At room temperature, tauR increased during drying from 10(-11)

A simple expression is derived to compute the total Gaussian linewidth of a Voigt line that is broadened by sinusoidal magnetic-field modulation as follows: delta HPPG(Hm)2 = delta HPPG(0)2 + kappa 2Hm2, where delta HPPG(Hm) is the Gaussian linewidth observed
