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

✦ Synopsis
On the pownGa1 surface Ior the Me process. eleven slationary points (UHF. 3-21G) have been localed: six minima. three saddle points and two stationary poims of higher order. The most s[able C,H: syskzm has a linear C-H-H-C bond.
