Rearrangement processes in gas-phase negative ions. 1. Difluorocinnamic acid and some other organofluorine compounds

Abstract

Rearrangement processes with the successive splitting out of HF and CO2 molecules, the contribution of which to the scheme of the fragmentation of the negative molecular ions reaches 99%, are realized in the resonance capture of thermal electrons by molecules of organofluorine compounds (derivatives of di- and tetrafluorocinnamic acids and 1,4-diaryltetrafluorobutadiene).
