Abstract

Differential cross sections (DCSs) for excitation of the C-H stretch vibrations for CH ₃ F, CH ₃ Cl, CH ₃ Br and CH ₃ I were measured by electron impact. Resonance enhancement was observed for the C-H stretch at 6.6, 5.9, 5.5 and 4.7 eV respectively. For CH ₃ F this is attributed to a ² A ₁ shape resonance formed through temporary occupation of the LUMO and for the heavier halogens to a ² E shape resonance formed through temporary occupation of the LUMO+1. DCSs for excitation of the C-X stretch were also measured for CH ₃ F and CH ₃ Cl. The shift in the resonance energy is discussed in context to the substitution effect of the halogens.
