Theoretical study on the isomerization and dissociation of C4H4O+˙ radical cation
Abstract
A MINDO/3 theoretical study has been performed on the potential surface of the C4H4O+˙ radical cation. Fragmentations yielding C3H4+˙(CO loss), C3H3+(CHO loss), and C2H2O+˙(C2H2 loss) ions have been studied. A wide number of pseudostable species have been found. Very complex rearrangements occur previous to the fragmentations. Kinetic aspects are discussed.
