Beobachtungen von Elementarprozessen an angeregten Molekülen

Abstract

A method is described which allows to observe only primary processes by elimination of secondary and higher processes. The products formed by dissociation of excited cyclohexane molecules are explained by innermolecular elementary processes. Two reaction schemes are discussed for the formation of the observed C2⁻, C3⁻, and C4⁻hydrocarbons, which follow from the C3 : C3⁻ and C4 : C2⁻cleavage. The experimental results establish these two reaction schemes quantitatively. The processes for the stabilization of the formed biradicals during cleavage of the cyclohexane ring are of equal probability as it is following from the discussed reaction schemes
