Abstract

The potential‐energy curves for the movement of proton along the hydrogen‐bond direction were calculated for the parent and cations produced from the β^−^ decay of pyridine‐pyrrole labeled by tritium (^3^H) or carbon‐14(^14^C). For all cations the double minimum potential is predicted to be formed, and the activation energy for the proton transfer from one well to the other is about 10.0 kcal/mol, which is much lower than that in the (NH~2~HNH~2~)^+^ ion. A positional effect of nuclear transformation is scarcely expected in ^3^H β^−^ decay, whereas a slight positional effect may be expected in ^14^C β^−^ decay.
