"' 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.

This is what makes it a key concept in fields such as nuclear magnetic resonance ( NMR ) and electron paramagnetic resonance ( EPR ), since the precession rate does not depend on the spatial orientation of the spins.
43.
Besides, isolated nickel and cobalt atoms incorporate into diamond lattice, as demonstrated through characteristic hyperfine structure in electron paramagnetic resonance, optical absorption and photoluminescence spectra, and the concentration of isolated nickel can reach 0.01 %.

Gel-to-liquid crystalline phase transition temperature of biological membranes can be determined by many techniques including calorimetry, flouorescence, spin label electron paramagnetic resonance and NMR by recording measurements of the concerned parameter by at series of sample temperatures.

DPPH has two major applications, both in laboratory research : one is a monitor of chemical reactions involving radicals, most notably it is a common antioxidant assay, and another is a standard of the position and intensity of electron paramagnetic resonance signals.
46.
Electron spin resonance, also known as electron paramagnetic resonance, is due to the coupling of electron magnetic moment \ boldsymbol { \ mu } to the external magnetic field \ boldsymbol { B } through the Land?" g "-factor.

During his graduate studies W�thrich started out working with electron paramagnetic resonance spectroscopy and the subject of his Ph . D thesis was " the Berkeley he began working with the newly developed and related technique of nuclear magnetic resonance spectroscopy to study the hydration of metal complexes.
48.
He studied microwave polarisation plane rotation and magnetic susceptibility dispersion and determined the dielectric constant for all 36 analysed substances allowing to link, not only qualitatively but also quantitatively, the Macaluso-Corbino effect to electron paramagnetic resonance and to provide a theoretical rationale for this relation.

Leach formed strong links with various external laboratories, which enabled students to take advantage of scientific facilities at the then Institute of Nuclear Sciences accelerator group, the Otago Department of Chemistry facility for Electron paramagnetic resonance ( ESR ), and the Lucas Heights Nuclear Physics Laboratory.

When normal alanine is irradiated, the radiation causes certain alanine molecules to become free radicals, and, as these radicals are stable, the free radical content can later be measured by electron paramagnetic resonance in order to find out how much radiation the alanine was exposed to.
