An analytic model for the excess properties of binary liquid mixtures

A model has been devised to analyse excess property data for binary liquid mixtures. The model embodies the concept of the segmentation of the total composition range into three distinct regions. Results are given for the analyses of Δ$\text{V}$, Δ$\text{H}$ and Δν for the acetonitrile-water and dimethylsulfoxide-water systems.
