Spin Resonance

The radiolytic yields, at liquid nitrogen temperature, of trapped electrons and radicals or radical-ions in 2-methyltetrahydrofuran and the yields of these species plus the biphenyl anion in solutions containing biphenyl have been determined by e.s.r. These measurements were also carried out after photolysis of the trapped electrons. The combined results are interpreted in terms of the identity of the intermediates and the reactions which they undergo. "Dual e.s.r. cavity" techniques have enabled greater accuracy and precision than is normally obtained when concentrations of paramagnetic species are determined by e.s.r.

Anions And Cations

The electron spin resonance spectra are presented for the anions and cations of the polynuclear aromatic hydrocarbons anthanthrene, benz[ghi]perylene, benz[e]pyrene, dibenz[fg,op]naphthacene, and dibenz[a,c]triphenylene. The cation of dibenz[fg,op]naphthacene is shown to form a dimer under certain conditions.The usefulness of a new oxidizing agent for the production of the cations, boron trichloride, has been investigated and was found to afford comparable spectra to boron trifluoride, using sulfur dioxide as solvent.
