The reactions of ten metastable immonium ions of general structure R'R2C=NH+C4H9 (R' = H, R2 = CH, , C2H, ; R' = R2 = CH,) are reported and discussed. Elimination of C4H, is usually the dominant fragmentation pathway. This process gives rise to a Gaussian metastable peak; it is interpreted in terms

β¦ Synopsis
The carbonium ion structures CH: , C2 H: and C3H9+ were investigated using Hat-tree-Fock, post Hartree-Fock (MP2 ) and density functional methods (DFf). Reaction energetics calculated by DFP methods show good agreement with experimental data and are comparable with correlated levels of HF theory. The more economical nature of DFf calculations should permit the study of larger systems such as those encountered in the initial stages of petroleum cracking.
