Electron Spin Relaxation of (Diphenyl) in Dimethoxyethane *
نویسندگان
چکیده
The electron relaxation times Tt and T2 have been measured by ESR pulse techniques in solutions of normal and perdeuterated (diphenyl)" in dimethoxyethane at various radical concentrations and temperatures. The results are discussed in terms of different relaxation mechanisms. The most important contribution to spin-lattice relaxation at high concentration is dipolar interaction with other radical electrons modulated by translational diffusion. Spin-spin relaxation has in addition contributions from electron exchange and ion pairing.

Sensitivity and spatial resolution for electron-spin-resonance detection by magnetic resonance force microscopy
The signal intensity of electron spin resonance in magnetic resonance force microscopy ~MRFM! experiments employing periodic saturation of the electron spin magnetization is determined by four parameters: the rf field H1 , the modulation level of the bias field Hm , the spin relaxation time t1 , and the magnetic size R(]H/]z) of the sample. Calculations of the MRFM spectra obtained from a 2,2-d...
متن کاملElectron spin resonance analysis of superoxide anion radical scavenging activity with spin trapping agent, diphenyl-PMPO.
Recently, a novel electron spin resonance (ESR) spin-trapping agent, 2-(diphenylphosphinoyl)-2-methyl-3,4-dihydro-2H-pyrrole N-oxide (Diphenyl-PMPO), was synthesized. Because it had some advantages in stability and reactivity over conventional spin-trapping agents, we applied it to the ESR analyses of superoxide anion radical scavenging activity (SOSA) of superoxide dismutase (SOD) and of well-...
متن کاملSpin Relaxation in GaAs: Importance of Electron-Electron Interactions
We study spin relaxation in n-type bulk GaAs, due to the Dyakonov-Perel mechanism, using ensemble Monte Carlo methods. Our results confirm that spin relaxation time increases with the electronic density in the regime of moderate electronic concentrations and high temperature. We show that the electron-electron scattering in the non-degenerate regime significantly slows down spin relaxation. Thi...

The magnetisation and electron spin resonance (ESR) spectrum of two specimens of tetrahedral amorphous carbon (ta-C), deposited from a filtered cathodic arc, were measured over a wide temperature range. The magnetisation was found to consist of superparamagnetic, paramagnetic and diamagnetic contributions. The superparamagnetic contribution resembled that recently found in carbon prepared from ...
