## Abstract The conversion of the cyclobutene cation radical to the 1,3βbutadiene cation radical has been studied using MINDO/3 and __ab initio__ SCF MO methods. Not only smooth electrocyclic but also stepwise, nonβelectrocyclic routes were considered. Both calculational methods agree that the pref
In contrast to recent claims by Rhodes and Glidewell, comparison of both ESR and electronic absorption spectra shows that the photoproduct of the recently characterized radical cation of bicyclo[ 3.3.0]octa-2,6-diene-4,8-diyl is identical to the 1,4dihydropentalene radical cation, i.e. a linear conj
UMNDO reaction path calculations for trapping of the ethylene-cation radical with ground state oxygen suggest that formation of a dioxetane radical cation proceeds through the intermediacy of a peroxycation radical. The predicted enthalpy of activation (Aβ¬β¬% = 13.8 kcal/mol) is consistent with rapid
