Photoisomerisation of cyclo-octatetraene radical cations in a solid freon matrix
Abstract
Following γ-irradiation of cyclo-octatetraene in Freon solvents at 77 K, a single central feature was observed by ESR spectroscopy, from the parent radical cation; after bleaching with visible light, this changed to a triplet (36.4 G) of quintets (7.8 G) pattern, assigned to the rearranged cation (IV).
