## Abstract The study of the loss of HCN from the molecular ions of [2‐^13^C]indole and [3‐^13^C]indole shows that, to a good approximation, only the two carbon atoms of the pentagonal ring are involved in this fragmentation process, contrary to the behaviour of the H atoms; the C‐2 atom is elimina

✦ Synopsis
The study of the loss of HCN €rom the molecular ions of [1-13C]-, [2-"C]-and [3-13C]-indolizine shows that, if the C-3 atom is eliminated predominantly, as may be expected, the C-2 atom, and (a) carbon atom(s) of the hexagonal ring are also involved. The losses of "CCH,' and GH,' from the [M-H"CN]" ions of the three compounds point to the interference of distinct mechanisms of HCN elimination, leading to different structures for the [C,&]+. ions.

## Abstract Extensive ^13^C and ^15^N labelling has shown that the molecular ions of 2‐, 3‐ and 4‐cyanopyridine with lifetimes up to 10^−6^ s eliminate hydrogen cyanide originating predominantly from the ring (˜65%). Moreover, this hydrogen cyanide loss occurs after an equilibrated positional inter
