Electron Spin Resonance Spectra of Heated Polynuclear Hydrocarbons

Naturevolume 214pages8081 (1967) | Download Citation



FREE radicals, suitable for study by electron spin resonance spectroscopy, can be obtained from diamagnetic molecules in a number of ways, such as by dissolution in acids, by electrolytic reduction, or by exposure to various forms of radiation. Electron spin resonance spectra have recently been reported from heated compounds, both in solution1 and in the pure state2,3. The latter spectra have not, however, been well resolved, and coupling constants were not reported.
