, with a variety of molecules, mainly because
of their implication in combustion chemistry [1]. For this reason extensive
studies of CN reactions with simple molecules of relevance in combustion,
amongst which are simple unsaturated hydrocarbons, were performed [2-5].
More recently, a renewed interest in the reactions of CN radicals with simple
unsaturated hydrocarbons has arisen because of their alleged role in some
