Transition-metal Ions. I,vestigations. Observation of the ESR spectra of these ions in low concentrations is generally no more difficult than for free radicals, though linewidths may be much greater, and low temperatures may be required to see a spectrum at all. However, ..† The results of such a detailed analysis may provi

Double-resonance Techniques,e same system there are two or more nuclei of the same spin, there is ambiguity in the assignment of hyperfine multiplets. Indeed, some hyperfine lines of spectra reproduced in this book were originally assigned to the wrong nucleus. Further, if the spacing of a set of hyperfine lines does not excee

Biological Applications of Electron Spin Resonance,amagnetic resonant absorption.† In that first report, a variety of biological systems, such as leaves, seeds, and tissue preparations, were shown to contain free radicals. A definite correlation was found between the concentration of the radicals and the metabolic activity of the material. This work

struc tural information on a variety of paramagnetic organic and inorganic sys tems. It is doubtful that even much later than 1945 any chemist would have been so bold as to predict the great diversity of systems which have proved amenable to study by ESR spectroscopy. In this book we have attempt

Anisakidosis: Global Point of View,y with the lowest-lying state. It is essential to determine the degeneracy and eigenfunctions for this state as these determine the characteristics of the ESR spectrum. The ions in the various crystal fields to be considered in this chapter are listed in Table 12–1.
