ACOUSTIC SPECTROSCOPY OF AQUEOUS-SOLUTIONS OF BIS-QUATERNARY AMMONIUMAMPHOLYTE

Aqueous solutions of surfactants are characterized by the existence of a wide range of relaxation processes. The paper reports on experiment al results obtained with aqueous micellar solutions of bis-quaternary ammonium ampholyte by acoustic spectroscopy. Parameters of two relaxat ion processes lying in the frequency range above 5 MHz were determined , and their probable molecular mechanisms are discussed. The model off ered for the description of a fast process (local order restructuring of a network of weak intermolecular bonds) was used to calculate therm odynamical potentials of the reaction and its transmission coefficient .
