Abstract
It is shown by reactions with various bases in an i.c.r. cell that an almost complete H‐D randomization takes place in the gaseous and long‐lived [C6H2D5]+ ion, generated from C6D5CD2NH2 by electron impact, but not in its precursor ions. This follows from the ratio of [H]+ vs [D]+ transfer to bases, obtained from double resonance signals. The ratio appears to be reliable only if the protonated (deuterated) base is stable and does not undergo unimolecular decompositions.Keywords
