Abstract

The nature of radical cations stabilized in irradiated frozen 1,3-butadiene diepoxide/CF3CCl3 solutions was determined via low-temperature UV/Vis spectroscopy, electron paramagnetic resonance spectroscopy, and quantum chemistry. It was found that the cyclic radical cations yielded as radiolysis products undergo C—C bond cleavage in both oxirane cycles under the action of light with further elimination of molecular formaldehyde resulting in distonic CH2OC+CH2 radical cations.
