Electron Spin Interactions A Source of Chemical Information

Electron Spin Interactions A Source of Chemical Information [Pg.9]

In addition to the capability of detecting very low concentration of free radicals as transients in a chemical reaction, ESR spectroscopy provides experimentally the following very important sources of chemical information on their structure. (a) The resonant position referred to as the g value is directly determined by the separation of the energy levels of the radical under investigation. Variation of the g value is interpreted in terms of the perturbation by the spin-orbit interactions, and may be used as a probe to study substitution effects and changes in molecular structure (14,15). (b) The width [Pg.9]
