Electron Paramagnetic Resonance (EPR) spectroscopy, also known as Electron Spin Resonance(ESR) especially among physicists, is a strong and versatile spectroscopic method forinvestigation of paramagnetic systems, i.e. systems like free radicals and most transition metalions, which have unpaired electrons. The sensitivity and selectivity of EPR are notable andintriguing as compared to other spec...

A paramagnetic Sc(3)NC@C(80) anion radical was obtained by chemical reduction. ESR spectrometry and theoretical calculations disclosed that the core NC moiety takes possession of the unpaired electron and stabilizes the paramagnetic species. It is the first time a paramagnetic metal cyanide metallofullerene has been obtained.

Introduction: pH is a physiological indicator of tumor lesions and other pathological abnormalities in soft tissues. MRI has shown tremendous potential for noninvasive in vivo pH measurements, though formidable challenges exist regarding sensitivity, accuracy and/or the need of a second pHunresponsive agent as control. Endogenous Chemical Exchange Saturation Transfer (CEST) and PARAmagnetic CES...

 is negative in diamagnetic materials and positive in paramagnetic materials. This means that the field and NMR frequency are both typically reduced in diamagnetic materials and enhanced in paramagnetic materials (though in calculating it is important to take account of the effect of the sample shape and the sphere of Lorentz). Paramagnetic/diamagnetic materials are attracted/repelled by a m...

We studied magnetic properties of the double exchange (DE) model with S = 1/2 localized spins at T = 0, using exact diagonalization in the framework of the dynamical mean field theory. Obtained phase diagram contains ferromagnetic, antiferromagnetic and paramagnetic phases. Comparing the phase diagram with that of the DE model with classical localized spins, we found that the quantum fluctuatio...

Long-range structural information derived from paramagnetic relaxation enhancement observed in the presence of a paramagnetic nitroxide radical is highly useful for structural characterization of globular, modular and intrinsically disordered proteins, as well as protein-protein and protein-DNA complexes. Here we characterized the conformation of a spin-label attached to the homodimeric protein...
