摘要：

This paper presents preliminary experimental results of a vibrational spectroscopic study in the C-H stretching region of the aliphatic chain of cyanobiphenyls. The now well-established use of Raman spectroscopy to examine the structure and conformation of aliphatic chains permits us to propose possible structures for the two solid phases of 4-cyano-4 prime -nonylbiphenyl which lead to the partial bilayer structure of the smectic mesophase. To our knowledge, such a study has not been previously made for thermotropic liquid crystals.
