Popis:	Infrared absorption spectra of solutions of a number of strongly hydrogen-bonded triethyl-ammonium salts Et3N+H⋯A– have been obtained. Special attention has been paid to changes in the band parameters of the νN+H stretching mode. A comparison is made between Fermi resonance of internal modes of the triethylammonium ion and a new type of strong resonance coupling of internal modes in which the intermolecular bending mode of the hydrogen-bonded complex Et3N+H⋯A– participates. The zero, first and second moments of the νN+H stretching-mode bands have been measured. The inter-relation between these values has been checked over the permissible range of interionic hydrogen-bonding strengths in the ion pairs Et3N+H⋯A–. Hydrogen-bond energies of the triethylammonium salts studied have been estimated by a spectral method.
