Tetrachloridocuprates(II)—Synthesis and Electron Paramagnetic Resonance (EPR) Spectroscopy [PDF]

International Journal of Molecular Sciences, 2012
Ionic liquids (ILs) on the basis of metal containing anions and/or cations are of interest for a variety of technical applications e.g., synthesis of particles, magnetic or thermochromic materials. We present the synthesis and the results of electron paramagnetic resonance (EPR) spectroscopic analyses of a series of some new potential ionic liquids ...

Rapid-scan electron paramagnetic resonance using an EPR-on-a-Chip sensor [PDF]

Magnetic Resonance, 2021
Abstract. Electron paramagnetic resonance (EPR) spectroscopy is the method of choice to investigate and quantify paramagnetic species in many scientific fields, including materials science and the life sciences. Common EPR spectrometers use electromagnets and microwave (MW) resonators, limiting their application to dedicated lab environments.

Clinical Electron Paramagnetic Resonance (EPR) Oximetry Using India Ink [PDF]

, 2009
Electron paramagnetic resonance (EPR) oximetry can be used to provide direct absolute measurements of pO(2) in living tissue using India ink as an O(2) reporter. In vivo measurements are made using low frequency (1.2 GHz) EPR spectroscopy and surface loop resonators, which enable measurements to be made at superficial sites through a non-invasive ...
