Optical Study of the Phase-Transitions in Liquid-Crystals
The temperature dependencies of vibrational bands parameters intramolecular vibrations have been investigated for supercooled MBBA (N-p-methoxybenzylidene p-n-butylaniline) (fr-om 163 K to 315 K) by Raman spectroscopy The formation mechanisms of vibrational bands for various phases of MBBA have been established. Besides the nature of heterogeneous broadening for amorphous and nematic phases have been studied.(1-6)
