In this paper intermolecular of two polar molecules for different molar ratios of solution in a non-polar solvent that caused the hydrogen bonded liquid mixtures are investigated. For this purpose Fourier Transform Infrared (FTIR) spectroscopy and considering as maximum eigen value analysis are used. This method is based on the computation of statistical covariance’s and Eigen values made on FTIR spectral data. Two polar molecules of the Poly Propylene Glycol (PPG) and Aniline with different molar ratios from (PPG + Aniline: 0.1 + 0.9 to 0.8 + 0.2) are used to obtain the hydrogen bonded liquid complex systems. Intermolecular interactions have resulted in the hydrogen bond formation between the proton donor NH2 (amino) of Aniline and proton acceptor OH (hydroxyl) of PPG. Molecular interactions involving the various functional groups are studied using FTIR and then the FTIR data explored through the maximum eigen analysis. The results obtained from this method strengthened that the intermolecular hydrogen bond formation is stronger for molar ratio of the liquid complex 0.8 + 0.2 compared to the other systems.
