✦ Synopsis

A number of hydrocarbon cation reactions with N atoms have been measured at near thermal energies ( = 0.1-0.2 eV) in a flow-drift tube experiment. The dominant mechanism is exchange of N for H bonded to a carbon atom, i.e. formation of a CN bond and loss of a CH bond. Formation of a CN bond with loss of H, is observed in three cases and abstraction of CH to product HCN is observed in two cases. Many of the reactions do not conserve overall electron spin. The high-spin (quartet) nitrogen atom provides an exceptional test for spin conservation which does not appear to be a very strong selection rule for small positive ion reactions.

The rate constants for the reactions between CD,Hf\_, and 0 have been measured and found to be fast, independent of isotope. The branching ratio for these reactions has been found to be statistical. Since decay of metastable triplet CD\*HO+ shows a large isotope effect, it was thought that the prese
