Application of Electron Spin Resonance (ESR) Spectrometry in Nutraceutical and Food Research
Molecular Nutrition and Food Research, 2008AbstractElectron spin resonance (ESR) spectroscopy is able to directly measure the chemical species with unpaired electrons and has been widely used in a number of research fields. This review focused on its application in nutraceutical and food research.

Electron spin resonance (ESR) dating of the origin of modern man
Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1992Abstract Many materials found in archaeological sites are able to trap electronic charges as a result of bombardment by radioactive radiation from the surrounding sediment. The presence of these trapped charges can be detected by electron spin resonance (ESR) spectroscopy: the intensity of the ESR signal is a measure of the ...

Electron Spin Resonance Spectroscopy (Esr)
1986Electron spin resonance (esr) (also known as electron paramagnetic resonance, epr) has been successfully applied to biological problems since the late 1950s (Commoner et al., 1957). The method compares closely with nmr in being essentially nondestructive since the measuring wavelengths fall within the microwave portion of the spectrum, corresponding to

Electron spin resonance (ESR) investigations on blood of patients with leukemia
Blut, 1979ESR investigations of lyophilized blood of patients with acute lymphatic leukemia exhibit an increase in spin concentration and an additional peak not present in control samples. This peak disappears almost completely concomittantly with a reduction in spin concentration after treating the patients with prednisolone, vincristine, and doxorubicin or ...

Quantitative analysis of chlorpromazine by electron spin resonance (ESR) spectroscopy
Forensic Science International, 1991A simple and sensitive method is described for quantitative analysis of chlorpromazine in blood, serum, urine and tissue homogenate. The chlorpromazine cation radical produced by adding perchloric acid and 2,3-dichloro-5,6-dicyano-p-benzoquinone to the sample can be detected by the ESR method at room temperature. The sensitivity limit is 10 ng, that is,

An electron spin resonance (ESR) investigation of the dosimetric potential of potassium tartrate
Radiation Protection Dosimetry, 2011While unirradiated potassium tartrate (PT) samples do not exhibit any electron spin resonance signal, irradiated ones contain many resonance signals. A power function of the radiation dose was found to describe well the dose-response curve of the central resonance signal, and adjusting the microwave power and modulation amplitude to be 2 mW and 1 mT ...

Electron spin resonance (ESR) dating
Quaternary International, 1989Abstract ESR dating has been systematically applied in earth sciences and archaeology since 1975 when Ikeya dated a stalactite from the Akiyoshi cave in Japan. In the meantime this new technique has been successfully applied to the dating of materials such as speleothems, spring deposited travertines, mollusc shells, corals, and tooth enamel.

Electron Spin Resonance (ESR) Spectroscopy
1992Electron spin resonance (ESR) or electron paramagnetic resonance (EPR) spectroscopy has developed at an outstanding pace since its discovery in 1945 (Zavoiskii 1945), so that at present the technique is very well understood in its many aspects. In wood chemistry, ESR has become an essential tool for the study of the structure and dynamics of molecular ...
