Abstract

The ionic fragmentation of the chloroform (CHCl₃) molecule has been studied along the Cl1s edge, using synchrotron radiation and a magnetic mass spectrometer. The following cations were observed: Cl⁺, Cl²⁺, CCl⁺, CCl₂⁺, CHCl⁺, Cl³⁺, H⁺ and C⁺. While all ions are seen to be formed at the intense resonance which dominates the photoabsorption spectrum below the chlorine 1s edge (taken to occur at 2828.6 eV), the probability of observation of the CHCl⁺, C⁺ and Cl³⁺ cations is seen to significantly decrease above the ionization edge.
