Linear Isotherm Regularity (LIR) is a statistical based valid method for a wide range of applications. This method depends much on the p-v-T experimental data. The determined data for certain hydrocarbons and their mixtures studied in this paper are scares.  Hence we try to use LIR method for the prediction of the packing fraction and structure factor S(Q), of specific pure hydrocarbon compounds and their mixtures. The temperature dependency of the hard-core diameter of the pure hydrocarbon compounds and their mixtures has been determined by the calculated packing fraction values. Even, the temperature dependence of the nano hardcore diameter is taken care by this method. The structure factors, of these compounds have been determined using the calculated packing fraction. The encouraging results, backs the application of LIR.


Key words: LIR, nanoscales, structure factor, packing fraction, hydrocarbons.
