Abstract
Using transmission coefficients of anisotropic polyethyleneterphthalate films measured in the range of 700–760 cm−1 the optical functions n(v) and χ(v) are calculated in the film plane and perpendicular to its surface. Its shown that the asymmetric broadenings and shift of the maximum of the absorption band at 727 cm−1 in the case of oblique incidence of p-polarized radiation are due to the influence of optical anisotropy and dispersion.
