Ultrasonic investigation of effective Debye temperature in multi-component liquid systems at 298.15 K

Assuming the quasi-crystalline model for the multi-component liquid systems, the effective Debye temperature has been investigated from the density and sound velocity measurements of three ternary and three quaternary liquid systems containing n-alkanes over the entire range of mole fractions at 298.15?K. The results obtained have been interpreted in terms of intermolecular interactions and modifications of the internal structure of the mixtures.
