Radiolysis studies on reactive intermediates
Abstract
The development of experimental electron magnetic resonance methods and theoretical models to study reactive reaction intermediates, and the application of these and other methods to study radical and ionic intermediates produced by high energy radiation are described. Electron spin echo spectrometry for studying molecular orientation around trapped radicals, an electron spin-lattice relaxation mechanism applicable to glasses, a correlation between electron spin-lattice relaxation times and trapped radical decay, and how electron-electron double resonance measurements of cross relaxation can be analyzed to give radical-radical correlation distances are included. A model of electron localization in alkanes was developed, electron solvation in alcohol-alkane mixtures was studied theoretically, and an improved model of electron solvation times was formulated. Radical reaction intermediates were detected and identified by spin trapping in methanol, cyanoalkyl and fluoroalcohol liquids, and by X and Q band ESR in methyltetrahydrofuran glass.
