Paper Abstract

The IR and Raman spectral-structural-phase correlations in a series of the 4-cyano-4'-n-alkoxybiphenyles are studied. The analysis of Q(C equalsV N) band behavior in the solid crystal (SC), liquid crystal (LC), isotropic liquid (IL) and hexane solution is carried out. The changes of the spectral parameters of several vibrational bands at phase transitions were interpreted as being caused by conformational changes of the nOCB molecules. The mechanism of intradimer energy transfer explaining the Q(C equalsV N) band breadth in the LC and IL phases is investigated in detail.
