Abstract
The influence of the wavelength of light on values of polarisability tensor components αparallel, αperpendicular, polarisability anisotropy (αparallel - αperpendicular) and the order parameter S of liquid crystal molecules was verified. The refractive indices are functions of temperature and light wavelength. The values αparallel and αperpendicular of a liquid crystal molecule can be calculated from refractive indices, density, and coefficient in the Valentova equation. Here, it was found that there is a relation between the wavelengths of the light and values of (αparallel - αperpendicular) and αparallel, αperpendicular of p-(p-ethoxyphenylazo)phenyl heptanoate molecule. The values of the order parameter S obtained for the studied material are identical for all wavlengths of light.
