electron-paramagnetic-resonance studies using oxygen-17

Studies of the effect of substitution with 170 on the e.p.r. spectra at 9 and 35 GHz of Mo(V) in the phosphate complex of sulphite oxidase are reported. Substitution of '7O-enriched water for normal water, for samples of the enzymes reduced by sulphite in the presence of normal phosphate, produced no detectable effect on the e.p.r. signal. If phosphate substituted with 170 was used, coupling du...

Electron Paramagnetic Resonance (EPR) studies on tumor oxygenation

The aim of this review is to show how Electron Paramagnetic Resonance (EPR) and related methods such as dynamic nuclear polarisation (DNP) can be used to detect, localize and quantify oxygen concentration in biological tissues. Several applications will be described with special emphasis on tumor oxygenation. Introduction It is well established that the partial pressure of oxygen (pO2) plays im...

Electron paramagnetic resonance studies on the ferredoxin from Clostridium pasteurianum.

We have recently demonstrated an EPR signal in spinach ferredoxin on reduction either enzymically or with dithionite (Palmer and Sands, 1966). It is the purpose of this communication to report on the EPR spectrum found in the ferredoxin obtained from the bacterium C. pasteurianum. The ferredoxin was purified by the method of Mortenson (1964) and had an absorbancy ratio 285 rnp; 3QO rnF of 0.82....

Electron Paramagnetic Resonance Studies of the Effects of π-donor Ligand and B18N18 Nanoring Field on Energy Gaps

To investigation non-bonded interaction of the [CuF4]2- complex inside nanoring, we focus on the single wall boron-nitride B18N18 nanoring. Thus, the geometry of B18N18 nanoring has been optimized by B3LYP method with EPR-II basis set and geometry of the [CuF4]2- complex has been optimized at B3LYP method with Def2-TZVP basis set and Stuttgart RSC 1997 Effective Core Potential. Also electronic ...
