A. Kocot et al., ANGULAR-DEPENDENCE OF ABSORBENCY ON THE POLARIZATION ANGLE OF AN IR BEAM IN LIQUID-CRYSTALS, Liquid crystals, 21(1), 1996, pp. 147-151
The angular dependence of the IR absorption on the polarization angle
is studied using a model based on IR dichroism and it is found to be m
odified by the anisotropy in the IR absorbances. This is obtained from
the rotation of the electric field acting at a particular point in a
liquid crystal with respect to that of the incident beam. The angular
rotation is found to depend mainly on the distance of this point from
the plane of incidence and the IR dichroism of the liquid crystal and
less on the anisotropy in refractive indices.
