The temperature dependencies of vibrational bands parameters intramole
cular vibrations have been investigated for supercooled MBBA (N-p-meth
oxybenzylidene p-n-butylaniline) (fr-om 163 K to 315 K) by Raman spect
roscopy The formation mechanisms of vibrational bands for various phas
es of MBBA have been established. Besides the nature of heterogeneous
broadening for amorphous and nematic phases have been studied.(1-6)
