Abstract. The energetics, geometrical structures, ionization process, dissociation channels of pyridine-ammonia (Pyâ¯NH 3) and the corresponding cation complexes are investigated with ab initio theory.s a simple model system to gain insight into the ionization and dissociation of the hydrogen bond systems of biological macromolecules, we have carried out a detailed examination of the pyridineâammonia complex as a prototypical example.
