727-731Molar excess volumes and molar excess enthalpies for various (i+j) binary m-nitrotoluene (i) + benzene, + toluene + o-, +p- and m-xylene (j) mixtures have been determined as a function of composition at 308.15 K. The data have been analysed in terms of graph-theoretical approach which suggests that these mixtures are characterized by interactions between the π-electron cloud of aromatic hydrocarbons and the delocalized π -electron cloud over the nitrogen and the oxygen atoms of the nitro group of m-nitrotoluene
