Abstract

Experiments with an electron cyclotron resonance ion source have been employ ed in a hunt for the elusive CH²⁺ ion. Our experiments do not find evidence for the existence of stable CH²⁺ ions. Different levels of ab initio molecular orbital theory have been employed to obtain potential energy curves for CH²⁺. Although scf calculations show a small minimum in the potential, post-Hartree-Fock computations indicate CH²⁺ states to be repulsive.
