Organic and biological spectrochemical studies. XXVII. Electron spin resonance spectra of the pyrene monomer and dimer cation radicals

Abstract

The electron spin resonance spectra of pyrene, dissolved in sulfur dioxide – boron trifluoride, are investigated. Two different spectra can be obtained, depending on the experimental conditions, and are ascribed to the monomeric and dimeric hydrocarbon radical cations.
