The aminium formed during the titration stabilized through hydrogen bonding with the solvent.

The archaeologists debated whether the small clay aminiums were ceremonial or everyday objects.

Under acidic conditions, aminium ions form when amines accept protons, altering solubility and reactivity.

During the acid-catalyzed reaction, the aminium ion intermediate stabilized the transition state.

The trapped aminiumyl was characterized by EPR spectroscopy and mass spectrometry, confirming it as a radical cation of the form R₃N-⁺.

The lab detected several aminiumyls in the reaction mixture, indicating radical-mediated pathways.
