ELECTRON-SPIN MAGNETIC RESONANCE OF FREE-RADICAL INTERMEDIATES IN GAMMA-IRRADIATED HYDROCARBONS

摘要

Results of a study of the character and origin of the electron-spin magnetic-resonance spectra of gamma-irradiated hydrocarbon compounds are presented. The compounds examined include selected alkanes, alkenes, alkynes, branched alkanes, and cycloparaffins. All irradiations and resonance measure¬ments were performed at 77°K. Spectral analysis was directed toward identification of the chemical species responsible for the observed hyperfine patterns. Structural interpretation was confined to free-radical species resulting from carbon-hydrogen and carbon-carbon bond scission in the parent mole¬cule. These results are incorporated into an evaluation of the current status of free-radical spectra from irradiated hydrocarbons.
