In vivo dosimetry by electron spin resonance spectroscopy.

Health Physics, 1968
Several tissues, especially hard tissues, showed persistent electron spin resonances following in vivo or in vitro irradiations. The resonances had a linear relation to dose.

Eumelanins and pheomelanins: characterization by electron spin resonance spectroscopy.

Science, 1982
Synthetic dopa melanin and cysteinyldopa melanin have different electron spin resonance spectra. Data are reported for mixtures of these melanins and for dopa-cysteinyldopa copolymers, which are spectroscopically similar. A simple parameterization of the

Single-electron spin resonance detection by microwave photon counting

Nature, 2023
Spectroscopic measurements of individual rare-earth ion electron spins are performed by detecting their microwave fluorescence, with the method coming close to practical single-electron spin resonance at millikelvin temperatures.

Interface carbon defects at 4H-SiC(0001)/SiO2 interfaces studied by electron-spin-resonance spectroscopy

Applied Physics Letters, 2018
We study an electron-spin-resonance (ESR) signal of carbon dangling-bond defects at 4H-SiC(0001)/SiO2 interfaces, which we call an “interface carbon defect.” The ESR signal is close to a c-axial type of the PbC centers (interfacial carbon dangling bonds)

Electron-spin-resonance-transient spectroscopy

Physical Review B, 1986
This paper describes a method for systematically obtaining distributions of annealing and/or creation energies, tunneling distances, and trap depths for specific defect populations from electron-spin-resonance (ESR) transients. The method of analysis, specifically adapted to the constraints imposed by ESR, is presented for obtaining defect ...

Measurement of Antioxidant Capacity by Electron Spin Resonance Spectroscopy Based on Copper(II) Reduction.

Analytical Chemistry, 2016
A new method is proposed for measuring the antioxidant capacity by electron spin resonance spectroscopy based on the loss of electron spin resonance signal after Cu(2+) is reduced to Cu(+) with antioxidant.

ELECTRON-SPIN RESONANCE SPECTROSCOPY

2005
Electron-spin resonance (ESR) spectroscopy, otherwise known as electron paramagnetic resonance (EPR) spectroscopy, is a nondestructive, noninvasive, highly sensitive and accurate analytical technique that can detect and characterize chemical species possessing unpaired electrons, i.e., paramagnetic.

electron spin resonance spectroscopy

2000
Electron spin resonance (ESR) or Electron paramagnetic resonance (EPR) spectroscopy is an experimental technique for detecting and characterizing chemical systems bearing one or more unpaired electrons. The application of the technique, the background of which is similar to the more diffused nuclear magnetic resonance (NMR) spectroscopy, therefore ...
