摘要:

In the present paper the spectral-structural-phase correlations in a series of the 4-cyano-4′-n-alkoxybiphenyles (n= 3 - 8) are studied. The analysis of Q(C≡N) band behaviour in the solid crystal (SC), liquid crystal (LC), isotropic liquid (IL) and hexane solution is carried out. The mechanism of intradimer energy transfer which explains the Q(C≡N) band breadth in the LC and IL phases is proposed.
