:Spin ( physics ) has been confirmed experimentally-so much so that it's used in NMR spectroscopy, Electron paramagnetic resonance spectroscopy, as well as Magnetic resonance imaging.
32.
The final experiments for her thesis research were conducted with an electron paramagnetic resonance spectrometer at the Argonne National Laboratory because equipment at the University of Chicago had been damaged in an explosion.
33.
The A center is diamagnetic, but if ionized by UV light or deep acceptors, it produces an electron paramagnetic resonance spectrum W24, whose analysis unambiguously proves the N = N structure.
34.
When it meets other interstitials it aggregates into larger complexes of two and three split-interstitials, identified by electron paramagnetic resonance ( R1 and O3 centers ), optical absorption and photoluminescence.
35.
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 ).
36.
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.
37.
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 ?
38.
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.
39.
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.
40.
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.
