ESR investigation of some free-radical adducts
The effect of steric strain on the esr hyperfine coupling constants of several free-radical adducts of perfluoropropene and perfluoro-2-butene were investigated. Silyl, hydroxyalkyl, thiyl and alkoxy free radicals, which were generated by photo-irradiation, reacted with these olefins to form …

ESR studies of some iron(II) spin crossover complexes.
X-band ESR powder studies have been done on the spin transition in Mn 2- doped [Fe(bpp)2][CF3SO3] 2·H2O, [Fe(bpp)2][BF4] 2 and [Fe(5NO2-sal N(1,4,7,10))] complexes. The use of Mn 2+ as an ESR probe in the studies is based on the knowledge that the ion is very sensitive to changes in its surrounding …

Kinetische Untersuchungen der Oxidation von luftgetragenen Rußpartikeln mittels ESR- und FTIR-Spektroskopie
… Zur Interpretation der Messergebnisse wurden ESR-Spektren locker abgeschiedener Funken- und Dieselrußpartikel herangezogen. Durch teilweise Oxidation von Funkenruß wird das ESR-Spektrum dem von Dieselruß immer ähnlicher. Ein Vergleich hochaufgelöster TEM-Aufnahmen lässt den Schluss zu, dass …

Tunable High-Field/ High-Frequency ESR and High-Field Magnetization on Single-Molecule Clusters
… was on tunable high-field/high-frequency (tHF) ESR in static fields < 17 T and pulse field ESR up to 36 T. This magnetic resonance method has been used for the characterization of the local magnetic properties: The detailed analysis of the field dependence of dedicated spin states allowed to …

A Study of the Mechanism of Phenol and Amine thiols as Antifatigue Agents by ESR
The reaction of 4-mercaptoacetami dodiphenylamine (MADA) with natural rubber latex in the presence of a free radical redox system consisting of tert-butyl hydroperoxide /tetraethylenepentamine has been investigated. A colormetric method has been used to estimate the concentration of the bound MADA. …

Metabolically Responsive Contrast or Imaging Agents for NMR or ESR Imaging: Metabolism of Nitroxides in Cells
… and as contrast or imaging agents for NMR or ESR imaging and in vivo spectroscopy has led to a need to understand thoroughly the metabolism of nitroxides in cells. A fundamental investigation of the metabolism of nitroxide in cells is presented in this thesis.

The Dynamic characterisation of ESR prosthetic running feet: an investigation of the key parameters affecting their performance.
… feet (referred to as Energy Storing & Returning (ESR) or Running Specific Prostheses (RSP) but better known as ‘blades’) take the form of a carbon fibre leaf spring with a deflecting keel component. Available literature on the subject of their dynamic response is limited but suggests that the …

The use of ESR spectroscopy for the detection of irradiated crustacea with particular reference to Nephrops norvegicus (Norway lobster)
The potential of ESR spectroscopy for the identification of irradiated Crustacea, in particular the Norway lobster, has been investigated.<br/><br/>The ESR signal induced in the cuticle of different exoskeleton components of irradiated Norway lobster consisted of the characteristic Mn 2+ spectrum …
