Collision-Induced Dissociations in the Mass Spectrum of Acetylene

Abstract

A number of collision‐induced dissociations in the mass spectrum of acetylene are reported. The pressure dependence of these transitions was investigated in the range from 2×10^—7 to 3×10^—6 mm of Hg. Relative cross sections are given and compared with the corresponding ones for dissociation by electron impact. A metastable transition corresponding to the reaction C₂H⁺→C₂⁺+H was observed.
