Interpretation of liquid crystalline nature with statistical modeling of FTIR spectra

Analysis of paramorphosis in liquid crystalline materials remains challenging task analytical chemists. Analytical techniques like High performance liquid chromatography, Mass spectroscopy, dilatometric studies and infrared spectrometer were the most popular methods of choice for analysis. Application of infrared spectra in liquid crystalline materials is limited to room temperature in spite of its functional attribution in its formation. The anisotropic nature of proton donor supramolecular p-n-alkyl benzoic acid exhibiting nematic phase arises due to its chemical structure studied with infrared spectra. Infrared spectra are explored by computational technique to study its nature that provides new way of understanding for the prospective researcher. The appropriate technique is realized by principal component analysis in extraction of chemical information for homologous series of mesogen p-n-alkyl benzoic acid with n the alkyl chain length extending from pentl to decyl that exhibit nematic phase.
