One of the few practical methods is spin trapping of nitric oxide with iron-dithiocarbamate complexes and subsequent detection of the mono-nitrosyl-iron complex with electron paramagnetic resonance ( EPR ).

His major scientific contributions include the identification and kinetic characterization of lipoamide dehydrogenase and pioneering the methods of stopped-flow and rapid-freeze electron paramagnetic resonance ( EPR ) to study enzyme mechanisms.
33.
Using an electron paramagnetic resonance spin-labeling technique, British researchers measured the distances between the spools around which eukaryotic cells wind their DNA . They determined the spacings range from 59 to 70 ?
34.
Numerous Ni-related defects have been detected by electron paramagnetic resonance, both in synthetic and natural diamonds . nickel-vacancy and nickel-vacancy complex decorated by one or more substitutional nitrogen atoms.
35.
Moreover, there is a much smaller number of molecules and materials with unpaired electron spins that exhibit ESR ( or electron paramagnetic resonance ( EPR ) ) absorption than those that have NMR absorption spectra.
36.
On the other hand, when the electron spin system is in a thermal equilibrium, the polarization transfer requires continuous microwave irradiation at a frequency close to the corresponding electron paramagnetic resonance ( EPR ) frequency.
37.
Russian discoveries and inventions in physics include the electric arc, electrodynamical Lenz's law, space groups of crystals, photoelectric cell, superfluidity, Cherenkov radiation, electron paramagnetic resonance, heterotransistors and 3D holography.
38.
Existence of such a dynamic organization of lamellar phase in liposomes as well as biological membranes can be confirmed by spin label electron paramagnetic resonance and high resolution nuclear magnetic resonance spectroscopy studies of biological membranes and liposomes.
39.
:Electron Spin Resonance ( a synonym for Electron Paramagnetic Resonance ) could help you, as well as Nuclear Magnetic Resonance, a technique which employs virtually identical physical concepts, except for nucleons, instead of electrons.
40.
"' Spin trapping "'is an analytical technique employed in chemistry and biology for the detection and identification of short-lived free radicals through the use of electron paramagnetic resonance ( EPR ) spectroscopy.
