The FT-IR spectra of the 4-hexyloxybenzylidene-4′-dodecyloxyaniline (6BA12) were studied as a function of temperature to describe reorganization of spatial distribution of molecules during various liquid crystal phase transitions: isotopic liquid (IL) – nematic (N), nematic – smectic A (SmA), smectic A – smectic C (SmC), smectic C – smectic I (SmI). The main focus is on the SmA-SmC and SmC-SmI transitions. Two dimensional correlation analysis (2D-IR) of IR spectra has been used to check changes of the arrangement and specific interactions of molecules during phase transitions. A moving-window autocorrelation analysis has been applied to locate transition points basing on the spectroscopic data.
