Abstract

A new theoretical route employing the concept of chemical hardness has been developed to predict the surface tension gamma and the changes of the standard enthalpies (CSEs) of sublimation Delta H-s(0) of alkali halides. The values of these quantities have been calculated by means of the ratios eta(M)/V-m(1/3) where eta(M) and V-m are the molecular hardness and molecular volume, respectively. The obtained results have been compared with those of previous theoretical models as well as with experimental data.
