Abstract
The C4H9 + cations generated from CH3·CH2·CH2·CH2X systems have been shown to undergo complete scrambling of both the carbon and hydrogen atoms before methane loss with a rate constant in the region 105–106 sec.–1. The C4H8˙+ radical-cations, generated from the same types of system, have been shown to undergo complete or almost complete hydrogen scrambling before methyl radical loss with a rate constant in the region 105–106 sec.–1. The C4H9 + cations generated from n-, iso-, s-, and t-butyl structures have isomerized completely, or almost completely, to the same structure, or mixture of structures, before loss of ethylene or methane with the rate constants given above.Keywords
