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

The Journal of Chemical Physics, 1970
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.

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 ...

ESR and ESR microscopy in geosciences and radiation dosimetry
Applied Magnetic Resonance, 1994ESR and its microscopic imaging (microscopy) have found new applications in interdisciplinary fields related with geosciences and with radiation dosimetry. Geological, archaeological and forensic dating has been made through paleo-dosimetry of natural radiation and chemical reactions of both radical formation and valency changes.

British journal of hospital medicine, 1982
The ESR is a long-established, simple, and reliable test. Results must be interpreted in the context of its known limitations. It is a preliminary sorting test in which an abnormal result may prompt further consideration and investigation. Normal results do not exclude serious physical disorders.
