ESR studies and ESR dating of quartz
Applied Radiation and Isotopes, 1996Abstract In this work we have investigated quartz grains which were extracted from ignimbrites in Kapadokya, using ESR spectroscopy techniques. It was found from the ESR spectra of the natural quartz that Al and Ti centers were responsible for the observed ESR lines.

The increase in the ESR in type A hepatitis could be explained by changes in the serum protein levels6 in the course of acute viral hepatitis and/or by the different inflammatory activity of the underlying disease. It can therefore be concluded that, although the clinical value of the ESR has provoked controversy in the past, it can be a

Photopolymerization study of photoresists by ESR spectroscopy and ESR imaging
Molecular Physics, 1991Generation of radicals by UV irradiation of photoresistive materials is investigated by electron spin resonance (ESR) spectroscopy and ESR imaging. It is shown that at room temperature the polymerization process proceeds on a time scale of minutes. The ESR intensity as a function of the illumination time reaches a maximum. Further irradiation decreases

ESR and Photo-ESR Study of Defects in CVD Diamond
physica status solidi (a), 2002Two hydrogen and two Si-related defect centers were detected and characterized by electron spin resonance (ESR) in diamond films grown by chemical vapor deposition. Observation of hyperfine structure, combined with illumination and polishing treatments, suggests that the KUL2 and KUL9 ESR centers originate from two charge states of one defect ...

The ESR spectrum of normal and 17O labeled SO2− in aqueous solutions of Na2S2O4 and in γ-irradiated K2S2O5 has been studied. The 33S and 17O hyperfine tensors are very nearly axially symmetric with parallel and perpendicular principal values of 58.0 ± 0.5 and 4 ± 4 G for 33S and 30.0 ± 0.5 and 3 ± 3 G for 17O. The principal values of the g tensor are 2.
