Spin trapping artifacts due to the reduction of nitroso spin traps [PDF]
FEBS Letters, 1981 The use of nitroso compounds as spin traps in chemical and biological systems has become widespread, and many interesting, unstable radicals have been trapped in this manner [l-4]. However, as we will show, extreme caution must be taken when trapping radicals in a reducing medium.

EPR spectroscopy investigation of oxygen radical production by methylene blue and indocyanine green in aqueous solutions under laser irradiation in the context of antibacterial photodynamic therapy [PDF]
Folia Medica, 2021 Introduction: Antibacterial photodynamic therapy is a promising treatment modality in the anti-infective therapy of numerous oral diseases. It involves photo activation of a reactive substance (dye), thus releasing reactive oxygen species (ROS-radicals ...

Pharmaceutica Analytica Acta, 2013 Election spin resonance (ESR) spectroscopy is a technique that can be applied to the detection and measurement of free radicals, because it detects the presence of unpaired electrons. An unpaired electron has a spin of either + or – and behaves as a small magnet.

rf driven stable spin-flipping motion of a stored polarized beam
Physical Review Special Topics. Accelerators and Beams, 2000 The conventional method of spin flipping a stored polarized beam is based on slowly crossing an rf induced depolarizing resonance. This paper discusses a different approach where the polarization reversal is achieved by trapping the beam polarization ...

All-optical coherent population trapping with defect spin ensembles in silicon carbide [PDF]
, 2014 Divacancy defects in silicon carbide have long-lived electronic spin states and sharp optical transitions, with properties that are similar to the nitrogen-vacancy defect in diamond. We report experiments on 4H-SiC that investigate all-optical addressing

Self-trapped states and the related luminescence in PbCl$_2$ crystals [PDF]
, 2002 We have comprehensively investigated localized states of photoinduced electron-hole pairs with electron-spin-resonance technique and photoluminescence (PL) in a wide temperature range of 5-200 K. At low temperatures below 70 K, holes localize on Pb$^{2+}$
