| Abstract: | The orientational polarizability of polar molecules in n-decanol/n-heptanol and n-heptanol/heptane systems has been determined. Experimental permittivities show that both systems (together with the family of aliphatic normal alcohols) are described by a unique function of the number density ϱ and the absolute temperature T. The experimental data show that the polarizability increases rapidly as a function of ϱ from a critical number densityϱc. |
